DATA COMMUNICATION PERFORMANCE TESTING OF ACTS

Marjorie L. Weibell

The results of a series of data communication tests, which define the digital end-toend performance of the Advanced Communication Technology Satellite (ACTS),

are presented. The experiment consisted of a test set characterization to determine

the effect of the test set on the results, a preliminary characterization to define the

failure/nonperformance outcome thresholds, and a full characterization. The

experiments' design, execution, and analysis comply with the American National

Standards X3.102 and X3.141. The tests showed that ACTS has a very clean data

channel (only one lost byte was recorded during all the tests), the X.25 packet mode

did not perform as well as expected, and the parameter estimates did not vary

substantially over time or destination location.

1. BACKGROUND

Spurred by emerging technologies such as personal communications services (PCS), asynchronous

transfer mode (ATM), and the government's vision of a high-speed network accessible by all citizens

(evident in the National Information Infrastructure), speculation of future communications has

become headline news in even the most nontechnical magazines, newspapers, and journals. In the

new communications environment, everyone wants to be connected to everyone (or everything) else

at anytime. They ideally would like to transmit voice, video, and data at various data rates using

the same physical equipment and protocols. One envisioned application, supervisory control and

data acquisition (SCADA), operates by polling the status of geographically disperse systems such

as oil pipelines at rates up to once per second. At the other end of the spectrum, remote

supercomputers perform parallel processing at data rates up to 1 Gbps. In between these extremes

are desktop conferencing (from 64 kbps to 384 kbps), video conferencing, and video on demand.

Most applications can be implemented using either wireless systems or wire/fiber systems. This is,

in part, a result of the new emerging satellite and ground segment technologies, in which "more and

Information Administration, U.S. Department of Commerce, Boulder, CO 80303.
more satellite equipment will meet terrestrial standards, leading to convergence of ground- and skybased technologies into one seamless system." [1] The choice of a transmission medium is often

based on parameters such as the cost or time ofimplementation. Given these parameters, satellites

may be the preferred choice in the following situations: (1) for areas that do not offer terrestrial

service at the data rates a user requires (e.g., in Colorado, there are many areas that still only offer

service from analog switches); (2) for connecting remote networks using specialized protocols (e.g.,

Integrated Services Digital Networks (ISDN) and ATM) and/or operating at high-speeds (e.g.,

OC-12); (3) for emergency situations when the terrestrial network has been destroyed; (4) for

geographically disperse SCADA-type applications; (5) for worldwide wireless consumer

applications (e.g., PCS and paging); and (6) as a backup switch for load leveling of a terrestrial

network.

The tests described in this paper were performed on an advanced communication satellite system that

showcases several new space- and ground-based technologies. Specifically, the tests were performed

on NASA's Advanced Communication Technology Satellite (ACTS) which was launched in

September 1993. The system is experimental with enough fuel for four years of operation.

Throughout its operational life, more than 80 organizations [2] will test ACTS technical capabilities

and demonstrate new applications that ACTS can support. Examples of new technical capabilities

and applications include transmission data rates up to 622 Mbps (OC-12), remote medical and

educational services, and T1 (1.544 Mbps) video transmissions to aircraft.

NASA initially developed ACTS to reduce industry's risk in incorporating advanced technologies

in future satellite systems. Several commercial systems in the design stage plan on using ACTSdeveloped technologies. These systems include Motorala's Iridium, Hughes' Spaceway, and Norris'

Norstar. These systems are incorporating technologies developed on ACTS such as on-board

switching, spot beams, and Ka-band operation.

1.1 ACTS System Description

ACTS uses several newly developed technologies such as on-board baseband switching, scanning

and hopping spot beams, high data rate communications between users (OC-12), and Ka-band

operation (30/20 GHz). In addition, ACTS applies technologies available 30 years ago, like Demand

Assigned Multiple Access (DAMA), that opens the two-way video, data, and voice markets and

makes the system act more like a terrestrial switched circuit than a leased line like conventional

VSAT (very small aperture terminal) networks [1]. These technologies provide network flexibility,

2
on-demand digital services, and as much as three times the communications capacity for the same

weight as today's operational satellites. All in all, the use ofthese technologies results in a more cost

effective system when compared to today's satellites [3].

An ISDN interface, developed specifically for ACTS, translates the ISDN protocols into ACTS

orderwires.2 In a future satellite system that uses ISDN, the orderwires could be designed from the

very beginning to accommodate the ISDN call setup messages so no translations would be necessary.

Besides ISDN, frame relay and ATM interfaces are being developed to evaluate the satellite

transmission medium for these systems. The Institute for Telecommunication Sciences (ITS) is also

involved with a study of low data rate ATM (1.544 Mbps) over ACTS in a related project.

The ground segment, or Earth Station (ES), used in this experiment is called a TI-VSAT. The

TI-VSAT can communicate at a data rate of 1.792 Mbps (one 1'1 + four 64-kbps channels) with an

antenna size of 1.2 m in diameter. The 1'1-VSAT has an outdoor unit and an indoor unit. Figure 1

shows the outdoor unit which consists of the antenna (a parabolic dish), the radio frequency (RF)

feed, an intermediate power amplifier, and an intermediate frequency (IF) interface unit that mixes

the signal down to IF. The IF signals are transmitted over 100 feet of heliax cable to the indoor unit.

Figure 2 shows the indoor unit which consists of a controlling computer, a two-shelf, small central

office (CO), a frequency standard (rubidium oscillator), a modem, a DC power supply, and a manmachine interface. Due to the switching that occurs on-board the satellite, the electronics of the

1'1-VSAT are simplified compared to other ES systems and thus are more cost effective. Although

an experimental program and manufactured in small quantities, the TI-VSAT's cost was only

$260,000. In mass production, the cost would be expected to decrease significantly and has been

developed to be comparable on a cost-per-unit-of-data-bandwidth basis to existing Ku-band

terminals [5]. In addition, due to the TI-VSAT's small size, it can easily be installed by two people

(as was the unit pictured in Figure 1). This also affects the total cost because no equipment (e.g.,

a crane) is needed for installation.

2 Orderwires are dedicated two-way control channels through which the Earth Stations maintain

communications (for acquisition, synchronization, circuit request, and circuit assignment) with the ACTS master

control station (MCS). More detailed information can be found in [4].

1.2 Purpose of ACTS Experiment

For systems such as ACTS, users require different and additional information than was necessary

with repeater satellite systems.3 For example, with the use of DAMA, users will now have the

ability to request satellite circuit capacity dynamically. This is called an access request and may be

done in a similar way to an access request in the terrestrial network (e.g., lifting a voice handset and

dialing a phone number). Depending on the system loading or the existing weather conditions,

access may occur within a specified amount of time, or it may be denied or ignored. For a user that

requires short access times or a reliable access session, this may be intolerable. However, other users

may not have such usage restrictions. Therefore, in this example, a user would need to know the

access time and access probabilities in order to make an informed decision.

With this need in mind, the objective of this ACTS experiment was to define the data

communication performance provided to a pair of users who use an advanced communication

satellite as the transmission medium. Results from this experiment provide users with the

information they need to determine the suitability of a system such as ACTS for meeting their needs.

1.3 ACTS Unbiased Measurement System

Measurements were made using a workstation-based system that transfers, collects, and processes

data to produce estimated values of the American National Standard (ANS) X3.102 performance

parameters [6], listed in Table 1. The measurement software conforms to the standard ANS

X3.141 [7], which defines proper methods to estimate the ANS X3.102 parameters. The

measurement system treats the data communication system, ACTS and associated equipment, as a

black box. The measurements are made between two predefined users (the test software is the user)

shown in Figure 3. As shown in the figure, the user interface resides in the workstations and is

between the test software and a stream head to the X.25 application programming interface (API)

or the operating system (UNIX4

) for the ISDN and modem tests. In order to more accurately

determine the contribution of the ACTS system to the performance parameters and deduct the

contribution due to the test sets, the test software was run on the test sets in a back-to-back mode

3 For a repeater-type satellite, the system's signal-to-noise ratio provides an idea of how reliably the data

will be received, and the bandwidth provides an idea of how fast data will be transmitted.

(i.e., no satellite is used). By subtracting the back-to-back results from the results using ACTS, the

effective user interface can be shifted from the test software/stream head/operating system to the

ISDN mini-PBX/Earth Station (ES) interface for the ISDN and X.25 tests or to the TI-VSAT's

private branch exchange (PBX) for the modem tests.

The test software implements the three generic data communication session functions defined in

ANS X3.102: Access, User Information Transfer, and Disengagement. One workstation places a

call to a second, remote workstation over the data communication system and establishes a

connection in the Access phase. In the User Information Transfer (UIT) phase, a user file consisting

of pseudorandom data is transferred from one workstation to the other. At the conclusion of the file

transfer, one workstation requests disengagement. The two workstations disengage and return to an

idle state, thus finishing the Disengagement phase and ending the data communication session.

The data recorded during the data communication session (the extracted data) is reduced off-line.

The extracted data consists of state codes, which define the party responsible for generating a given

reference event, and times of occurrence. The off-line data reduction and analysis are performed by

consolidating the data files of the remote workstations onto one system and running a script which

implements the reduction/analysis phase of ANS X3.141. The data reduction/analysis phase results

in estimates of the ANS X3.102 performance parameters shown in Table 1.5 The parameters are

estimated at a 95% confidence level.

As implemented in the ITS version of the ANS X3.141 test software, analysis of the three data

communication functions is split into two testing periods. The Access and Disengagement functions

are analyzed during one testing period and the UIT function is analyzed in a separate testing period.

For the Access/Disengagement tests, one block of data is transferred for each Access/Disengagement

trial. For the UIT tests, a number of blocks are transferred one after another (i.e., without a delay

between the blocks) in a single Access/Disengagement attempt. The number of blocks transferred

is the number of UIT trials for the test.

The number of necessary trials are determined by the precision required. Due to the number of

parameters to be estimated, a single parameter was selected for each of the Access/Disengagement

tests and the UIT tests to be measured with the specified confidence level and precision. For the

Access/Disengagement and UIT tests, the parameters chosen were the Access Time and the Bit Error

X3.141.

Probability, respectively. The goal was to measure the Bit Error Probability with a relative precision

of 50%. Additionally, the goal was to measure the Access Time with an absolute precision of

0.5 seconds for the modem service tests and 0.1 seconds for the remainder of the services. The

modem service requires a different precision than other service tests because of testing time. The

modem Access/Disengagement tests take approximately 10 times longer to run than the other

service's tests. Therefore, to keep the testing time reasonable, the precision required was reduced.

The number of trials necessary to meet the given confidence level and precision were as follows:

modem tests: Access/Disengagement tests: 20 trials

UIT tests: 50 trials with 4000 bytes/block

X.25 service tests: Access/Disengagement tests: 100 trials

UIT tests: 50 trials with 4000 bytes/block

ISDN service tests6

: Access/Disengagement tests: 40 trials

Each test was repeated five times. Since the parameters' standard deviations were similar, the data

from the multiple tests was pooled. Pooling the test data results in a larger sample which should

provide more precise parameter estimates [8].

6 For the ISDN service tests, no UIT tests were run. The hardware used could not accommodate a full

64-kbps data rate. Section 2 describes how the User Infonnation Bit Transfer Rate is calculated for the ISDN

service from the X.25 service results.

2. TEST SET CHARACTERIZATION TESTS

To subtract out the contributions of the test set from the results of the ACTS characterization tests,

X3.141 tests must be run over the test sets with the smallest possible intervening network. The

"intervening network" consists of a single switch under laboratory conditions. Figure 4 shows the

configuration for the ISDN case. The other cases have a similar configuration.

Test set characterization tests were performed for each of the following services:

- modem at 9.6 kbps over a plain analog telephone line (modem service)

- X.25 over a 64-kbps circuit-switched channel (X.25 via circuit service)

- ISDN over a 64-kbps circuit-switched channel (ISDN service)

The only service that was not tested in this configuration but was tested over the satellite system was

the X.25 over a packet-switched channel (called X.25 via packet service). This is because, from the

test set's point of view, there is only a circuit-switched channel for this case (i.e., in both cases there

is a circuit-switched channel between the test set and the ISDN signal processor). For the X.25 via

packet service, the packet-switched channel exists between the packet handler in the local ISDN

Signal Processor (SP) attached to the local ES and the packet handler in the remote ISDN SP. This

is discussed in more detail in Section 3.

The results of the test set characterization are shown in Table 2. Each test was run five times and

the results from the five tests were analyzed together to obtain more accurate results. The results

from the individual tests appear in Appendix A. Table 2a shows the results for the modem service,

Table 2b shows the results for the X.25 via circuit service, and Table 2c shows the results for the

ISDN service. Since the tests were run under laboratory conditions, with a single switch acting as

the network, the channel was extremely clean and no Access/Disengagement or UIT failures

occurred. Therefore, only the delay, rate, and ancillary parameters are shown in Table 2.

Modem Service Results

As shown in Table 2a, the modem service resulted in a User Information Bit Transfer Rate of

7676 bps. The modem's timing is asynchronous; it requires one start bit and one stop bit for each

eight user data bits, as shown in Figure 5. This is an overhead rate of 20%. Thus, in the ideal case,

the use of start and stop bits would result in a throughput reduction of 1920 bps for a 9600-bps

modem. This results in an ideal User Information Bit Transfer Rate of 7680 bps which was within

4 bps of the measured value. Due to the clear channel between the test sets, (i.e., the test sets have

an essentially error free channel between them) no bit or block errors occurred.

The Access Time took approximately 33.5 seconds. This Access Time was approximately split into

10 seconds for the call to be dialed and connected, 13 seconds for the handshaking, 6 seconds to

receive the login prompt, and 4.5 seconds for the login/password/program initiation. Figure 6 shows

the timeline graphically. For disengagement, the source initiates the procedure and takes 8.0

seconds. The 8.0 seconds is split approximately between a few seconds waiting for the destination

to disconnect and 5 seconds to receive a "NO CONNECT" after exiting. The destination takes

approximately 2.2 seconds to disengage.

X.25 via Circuit Service Results

As shown in Table 2b, X.25 via circuit service resulted in a User Information Bit Transfer Rate of

approximately 63 kbps. There are three OSI layers that contribute to the overhead that results in a

User Information Bit Transfer Rate less than 64 kbps. The X.25 Packet Layer resides at layer 3,

the LAP-B protocol resides at layer 2, and the Sunlink X.25 WAN connection resides at layer 1.

The relationship between the three layers is shown in Figure 7.

- The Sunlink X.25 physical layer, layer 1, runs on top of a clear ISDN 64-kbps channel (i.e.,

no overhead is added). Therefore, there is no drop in data rate due to this layer.

- The layer 2 protocol, LAP-B, adds seven bytes of overhead to every information field.

The information field size was 1028 bytes (the packet size of the X.25 Packet Layer).

Therefore, the LAP-B frame size was 1035 bytes. The drop in data rate due to LAP-B

is 0.676% or 433 bps.

- X.25 adds four overhead bytes to every user data field. The user data field size used was

1024 bytes. Therefore, the packet size was 1028 bytes. The resulting drop in data rate due

to X.25 was 0.389% or 247 bps.

Adding all the overhead contributions results in a total data rate drop of 680 bps. Therefore, the

theoretical User Information Bit Transfer Rate would be 63320 bps. The highest User Information

Bit Transfer Rate throughput measured in the five tests was 63101 bps, which is close to the ideal

value. The lowest rate measured in the five tests was 62964 bps. The UNIX operating system,

which must also perform some housekeeping functions while running the tests, causes the variance

in the User Information Bit Transfer rates. The issuing of these housekeeping functions during a test

could conceivably reduce the rate by a few hundred bits per second.

The measured Access Time was 0.27 seconds with 41 % of this time attributed to the user.

Therefore, approximately 0.16 seconds of the Access Time was due solely to the system. The

majority of this time was due to the issuance of system calls to make the X.25 connection. Similar

Disengagement Times were also measured.

In the previous case, X.25 via circuit service, the channel is established prior to establishing the X.25

connections. Therefore, the Access Time is solely the time required to issue and respond to the X.25

CONNECT REQUEST message. For the ISDN service, the Access Time includes the time to setup

the satellite channel. In addition, the ISDN service uses a serial port that needs a login process to

connect to a remote machine. The workstations used in the test set delay the issuance of the login

to prevent unauthorized access (this is part of the operating system and cannot be changed). The

login prompt is delayed approximately 6 seconds. The time for the call to be completed (i.e., for the

workstations to be connected) took approximately 2 seconds and the login/password/program

initiation took approximately 6-7 seconds. All these times together resulted in a measured Access

Time of 15.1 seconds (as shown in Table 2c). The disengagement times measured were each

approximately a couple of seconds.

Due to the hardware used, there was no way to run the ISDN UIT tests at a full 64 kbps. This is due

to the lack of 64-kbps serial ports that can be written to directly. It was determined that the data rate

obtained on a straight ISDN channel could be calculated from the X.25 results since

(l) the X.25 tests were run on clean channels (i.e., no errors and thus no retransmissions

for the X.25 via circuit service), and

(2) the only difference between the straight ISDN and the X.25 piggybacked on top of

the ISDN service is that X.25 adds some overhead packets.

As calculated previously, the X.25 Packet Layer and LAP-B added 680 bps of overhead. Therefore,

the estimated User Information Bit Transfer Rate for an ISDN service was approximately 63.7 kbps.

3. PRELIMINARY CHARACTERIZATION TESTS

The ACTS characterization tests were split into two testing periods. The first testing period, the

Preliminary Experiment Period (PEP), determines an estimate of the performance parameters. The

parameter values must be estimated prior to the second testing period, the Full Experiment Period

(FEP), in order to set the thresholds for poor or nondelivered service. The thresholds are defined

proportional to a "specified value" of a performance parameter. For example, access denial occurs

when the duration of an individual access attempt exceeds three times the specified value of the

parameter Access Time. The specified value of the Access Time, used in the FEP, equals the sample

mean of the Access Time measured in the PEP.

The tests run in the PEP are similar to the tests run in the FEP with the exception that the preliminary

experiment is done for nonstressed link conditions and in a loop-back configuration. The nonstressed

conditions include clear weather and low traffic. Therefore, referring to the Access Time example

again, in times of extreme stress (heavy rain and/or heavy traffic), the system may take an

unacceptable amount of time to form a communication session between two points. This trial results

in an access denial outcome.

The preliminary characterization tests were run in May, July, October, and November of 1994. The

energy per bit per spectral noise density (Eb/No) of the ES and the bit error rate (BER) on other

channels than the one under test were measured to obtain a good understanding of how the link was

operating at the time of the tests.

3.1 Tests Performed

Four types of services were tested. The first was an ISDN connection over a circuit-switched channel

(ISDN service). The configuration of the equipment is shown in Figure 3. The data communication

equipment for the ISDN tests is shown at the bottom of the figure. This test began with setting up the

ISDN call and ended at the conclusion of the ISDN call.

The second service tested was X.25 over a packet-switched channel (X.25 via packet service). The

packet-switched channel is between the ISDN SP on the local and remote ends as shown in Figure 8.7

7 The data is sent from the originating Earth Station (ES) to the NASA Ground Station's (NGS) packet

router. The packet router puts the data on one outgoing broadcast channel to all the X.25-ready ESs. Each X.25-

ready ES determines if any of the data is addressed to itself. Therefore, the X.25 packet network uses a double hop

to get data from one ES to another ES.

Figure 8. X.25 packet-switched channel over ACTS.
Between the workstation and the ISDN SP, the channel is circuit switched. In addition, due to the

design of the ISDN SP, the X.25 is required to piggyback on top of the ISDN. Therefore, as seen

in Figure 8, the workstation outputs the X.25 fonnatted data into an ISDN tenninal adapter (TA).

The data is then routed through an ISDN mini-PBX to the ES/ISDN SP.

To implement an efficient X.25 packet network, the SP immediately acknowledges the packets. In

the case of an errored packet, only the errored packet is retransmitted by the packet handler in the

ISDN SP (i.e., selective repeat automatic repeat request (ARQ». Due to this design of immediate

acknowledgment and retransmission only of errored packets, the window and packet sizes used for

this service are small. The X.25 via packet service used a window size of 2 and a packet size of 128

bytes.

The way this test was originally conceived, the physical X.25 connection would be setup and tom

down for each Access/Disengagement test. However, the packet router was designed so that when

the "last" X.25 call is closed, the whole X.25 channel is closed. This includes an ISDN call that is

made to the local ISDN SP. Attempting to open the X.25 channel again results in failure. The only

way to fonn another X.25 connection is to restart the X.25 packet handler and packet router (which

means powering down the ES to restart the local ISDN SP and having the NASA Ground Station

(NGS) restart the packet router). Therefore, in order to run the test as intended by fonning and

ending several connections in a row, the experiment was changed so that the logical connection,

rather than the physical connection, is setup and tom down. So, to prepare for an X.25

packet-switched test, an ISDN call is made to the local SP and then a packet call is made between

the local and remote ISDN SPs. This call remains active during all the X.25 packet-switched tests.

Once these preparatory calls have been made, the data extraction software places an X.25 call from

the packet handler of the local SP through the packet router at the NGS to the packet handler of the

remote unit's SP. For this service, the Access Time is the time required to establish the X.25

connection through the NGS's packet router.

The third service tested was X.25 over a circuit-switched channel (X.25 via circuit service). Figure 9

shows the configuration of this test. The configuration is identical to the X.25 via packet service

except the ISDN call is made between the local tenninal adapter and the remote tenninal adapter

instead of between the local tenninal adapter and the local ISDN SP. In addition, the window and

packet sizes for the X.25 via circuit service were different from those for the X.25 via packet service.

The packet size was 1024 bytes and the window size was 127.

Figure 9. Equipment configuration for the X.25 via circuit service over ACTS.
Prior to the start of the test, an ISDN channel was established between the local and remote SPs.

Then the test was started with X.25 "CONNECT REQUEST." Since the satellite circuit was already

established in this case, the Access Time consisted solely of the amount of time to make the X.25

connection over the already existing satellite circuit. This connection does not take any additional

satellite resources, so the set up time was basically the satellite transmission delay to and from the

remote location (or about 0.5 seconds). The main interest in this test was to see the effects of the

channel's BER on the UIT data rate. Since X.25 retransmits errored packets and since the X.25

portion of the ISDN SP that immediately acknowledges the packets and only retransmits errored

packets was not used, all the data in the channel after an errored packet is received must be

retransmitted. This may severely impact the user-perceived data rate. This will show up in the full

characterization test when the system is operated in "degraded" situations (e.g., rain).

The fourth service tested was a modem call over a circuit-switched channel (modem service). The

modem was operated at 9.6 kbps. This test does not fully stress the satellite's 64-kbps channels as

does the X.25 service tests. However, it does provide some valuable information since this type of

configuration may be used. The test equipment configuration is shown in Figure 3 with the data

communication equipment shown at the bottom of the figure. For this test, the modem's error

correction was disabled in order to determine the channel's characteristics (rather than the error

correction protocol performance of a given modem).

3.2 Test Results

Table 3 shows the results of the PEP. The tests were run in a loopback mode, from the ITS ES to

ACTS and back to the ITS ES. Due to the clear weather conditions, no Access/Disengagement or

UIT errors were observed. Therefore, the failure probability parameters are not presented in Table 3.

Each test was run five times and the results of the five tests were analyzed together to obtain a more

representative result. The results from the individual tests can be seen in Appendix B.

Modem Service Results

Table 3a shows the results from the modem service test over ACTS. The Access Time increased

16.6 seconds over the test set characterization Access Time. This amount was expected since the

observed time to establish a voice call, using ACTS, is approximately 14 seconds. It also

approximately takes an additional 2.5 seconds for the login process' prompts and responses to go

over the satellite. Since the modem line is connected to the same type of card used for a voice call

(line circuit card in the T1-VSAT's PBX), a similar amount of time for call setup (i.e., 14 seconds)

was expected for the modem service test.

Surprisingly, the Source Disengagement Time decreased by 1.4 seconds from the test set

characterization Source Disengagement Time. The reason for the decrease is not known. The

Destination Disengagement Time increased by 0.28 seconds over the test set characterization value;

this is due to the one-way satellite delay from the destination test set to the originating test set (about

an eighth of a second delay from destination test set to satellite + an additional eighth of a second

delay from the satellite to the originating test set).

The Block Transfer Time increased by 0.19 seconds when going over ACTS. The User Information

Bit Transfer Rate was essentially the same as for the test set characterization. As before, the start

and stop overhead bits caused the reduction in bit rate from the modem data rate of 9.6 kbps.

X.25 via Circuit Service Results

Table 3b shows the results of the PEP for the X.25 via circuit service tests. The Access Time

increased by 0.58 seconds over the test set characterization value. For this service, data is sent

immediately after the X.25 connection is made (i.e., there is no login session). Since the start of data

transfer signals the end of the Access function, Access requires two hops to the satellite and back,

as shown in Figure 10.8 Therefore, the theoretical Access Time increase would be approximately

a half of a second (an eighth of a second from the originating user to the satellite + an eighth of a

second from the satellite to the destination + a quarter of a second back to the originating user). The

observed increase in Access Time is close to the expected increase.

The Source Disengagement Time also increased by 0.58 seconds. The reason for the increase is the

same as for the increase in the Access Time. The Destination Disengagement Time increased by

8 Figure 10 also illustrates that the ISDN channel is already established prior to the X.25 connection. This

was described previously in Section 3.1.

0.87 seconds over the test set characterization value. In addition, the User Fraction (UF) of

Destination Disengagement Time increased by more than 50 percentage points compared to the test

set characterization value. The reason for such a substantial increase is unknown. However, it is

interesting to note that the system portion of the Destination Disengagement Time stayed

approximately the same for the test set characterization and the PEP (0.22 seconds and 0.24 seconds,

respectively). It would seem that the system portion should have increased by approximately a

quarter of a second like for the modem service.

The User Information Bit Transfer Rate stayed approximately the same as the Rate for the test set

characterization (within the precision value). This was expected since the packet and window sizes

were large enough so that the channel was always full of data (i.e., the test set systems did not have

to wait for an acknowledgement). In addition, the Block Transfer Time increased by 0.11 seconds

over the test set characterization value. Some increase was expected since Block Transfer Time is

defined as the average value of the elapsed time between the start of block transfer (on the

originating end) and the end of block transfer (on the receiving end) and it takes a finite amount of

time for the data to be sent to and from the satellite. However, an increase of approximately a

quarter of a second was expected.

24
X.25 via Packet Service Results

Table 3c shows the PEP results for the X.25 via packet sendee tests. Since the connection between

the workstation and the ISDN SP is a circuit-switched channel, the results obtained in this PEP test

were compared to the X.25 via circuit service test set characterization results. The Access Time

increased by 1.2 seconds, the Source Disengagement Time increased by 104 seconds and the

Destination Disengagement Time increased by 2.0 seconds. These increases are the amount of time

it takes to set up or tear down the satellite X.25 packet-switched call through the packet router at the

NGS.

The User Information Bit Transfer Rate fell to lOA kbps. This performance reduction is due to a

hardware limitation in the ISDN SP. Contributing factors include the processing power and buffer

size in the ISDN SP and the latency in the NGS packet router.9 However, it is anticipated that the

performance will improve when the tests are run between two separate locations (i.e., two different

SPs handle the call versus only one SP handling the call). The performance is expected to increase

because in the loopback case (where only one SP is used), both packet ports in the ISDN SP are used

and the "data between the two [ISDN] SP cards are routed through the MAC [Macintosh computer]

host CPU.,,9 The limitation is on the outside vendor plugin card which cannot become a bus master.

For more information on the design and operation of the ISDN SP see [9].

ISDN Service Results

Table 3d shows the results of the PEP for the ISDN service. For this service, the Access Time

increased 8.4 seconds. Approximately 2.5 seconds of this increase was due to the transmission time

of a login session over the satellite. The remaining increase was due to the ISDN call setup time.

The Source Disengagement Time increased by 1.3 seconds and the Destination Disengagement Time

increased by 0.29 seconds. The reason the Source Disengagement Time increased by 1.3 seconds

is not known. The Destination Disengagement Time increase is approximately the one-way

transmission from the originating site to the receiving site, via the satellite.

3.3 Specified Values Used in the FEP

The parameter values presented in Table 3 are used to define the specified values for use in the FEP

tests. The specified values used are equal to the measured mean parameter values and are used to

determine the failure thresholds.

According to the ANS X3.102 standard, an access timeout occurs whenever the duration of an

individual access attempt exceeds three times the specified value of the Access Time. Similar

definitions, where the timeout threshold is three times the specified value, are used to define Block

Transfer, Source Disengagement, and Destination Disengagement timeouts.

A set of thresholds determines the value of the Transfer Denial Probability. The Transfer Denial

Probability depends on the measured values of the Bit Error Probability, Bit Loss Probability, Extra

Bit Probability and User Information Bit Transfer Rate. The standard defines the threshold for each

bit transfer failure probability as the square root of the specified value; the threshold for the User

Information Bit Transfer Rate is defined as one-third of the specified value. A Transfer denial

outcome is said to have been observed if the performance of a transfer availability trial is worse than

the threshold for any of the four parameters and the degradation is attributed to system

nonperformance. The ANS X3.1 02 standard [6] describes how to determine if the user or the system

should be attributed with nonperformance.

The data reduction software looks for the specified values in the files spi.acd, for the

Access/Disengagement tests and spi.xfr, for the User Information Transfer tests. Table 4 shows the

content of each line in spi.acd and Table 5 shows the equivalent information in spi.xfr. The first line

contains the words SPECIFICATIONS INPUT. The second line contains an identifier that specifies

the type of test the spi file is used to evaluate. This identifier can be blank or contain any set of

words. The identifier is not used by the program. It is for the benefit of the user. The third line

contains an assessment option code. The first number is for Access, the second number is for User

Information Transfer, and the third number is for Disengagement. The option code is 1 if the option

is to be evaluated and 0 if the option is not to be evaluated. Since the measurement software expects

the Access and Disengagement parameters to be evaluated in one run and the User Information

Transfer parameters to be evaluated in a separate run, the codes used should be

for Access/Disengagement tests and

1 o

o 1 o

for User Information Transfer tests. The remaining lines are explained sufficiently in the tables.

Figures 11 through 14 show the spi files used in the FEP tests; they contain the specified

performance parameter values. The User Information Transfer tests require specified performance

parameter values for the failure probability parameters. However, as stated earlier, no bit errors

occurred in the PEP. Therefore, the Bit Error Probability was specified at the designed performance

level of the T1-VSAT (i.e., BER 1O-~ and the Bit Loss and Extra Bit Probabilities were specified

to be two orders of magnitudes better than the Bit Error Probability. The remaining specified values

carne from the measured mean parameter values.

4. FULL CHARACTERIZATION TESTS

The FEP tests were performed from the ITS site in Boulder, CO to the NASA Lewis Research

Center in Cleveland, OH over a two-month period from late December to late February, 1995. The

results were analyzed using the evaluation thresholds determined by the PEP tests.

Originally, the FEP tests were to be conducted over a six-month period, split between two different

destination locations. However, because the mean PEP and FEP parameter estimates were so

similar, they were considered to come from the same population, and thus the FEP tests were cut

short.

4.1 FEP Results

Tables 6a through 9a show the results of the FEP. The tests were run under the prevailing weather

and traffic conditions. For all of the FEP tests, the ITS ES's Eb/No varied by only 3.0 dB. This

value is within the ES design specification and therefore did not result in the generation of bit errors.

For the NASA ES, the Eb/No varied by 6.4 dB over all the tests. However, two different antenna

sizes were used on the NASA ES - a 2.4-m antenna for a majority of the tests and a l.2-m antenna

for the remaining tests. When the signal level was evaluated with respect to the antenna size, the

Eb/No varied by only 4.1 dB when the 2.4-m antenna was used and by only 1.5 dB when the 1.2-m

antenna was used. The 4. I-dB signal level variation is not within the design specification of 3.0 dB

(without invoking the Forward Error Correction); however, due to the use of the 2.4-m antenna, no

bit errors were generated. Therefore, even though the tests were not solely run under clear weather

conditions, the ES performance did not change substantially for any of the tests. There were no

Access/Disengagement errors during the FEP and only one UIT error occurred (for the modem

service tests).

Each test was run a number of times and the results from the tests were analyzed together to obtain

a more representative result. The results from the individual tests are included in Appendix C.

Modem Service Results

Table 6a shows the time and rate parameter estimates for the modem service tests. Comparing this

table to Table 3a shows a striking similarity in the estimates of the performance parameters. To

prove the similarity of the estimated parameters, the data was analyzed to determine if the FEP and

the PEP data could be pooled. The results of the pooling are shown in Table 6b, as are the rest of

the performance parameter estimates.

Table 6b specifies different levels of pooling - pooling all of the trial estimates (trials), pooling the

test means (tests), and pooling the level means (levels).l0 The first type of pooling examines the null

hypothesis that all test means are equal. The parameter test mean for test numberj, a. is calculated J.

by

10 Tests are made up of a number of trials. For example, for the AccesslDisengagement modem tests, each

test was made up of 20 trials.

can be accepted, there is a significant difference among the parameter estimates obtained from the

different destination locations. The means of each level of the selected variable condition

(destination location in this case) are pooled. This pooling provides the least precision of the three.

For the modem tests, all the parameters can be considered to come from the same population with

the exception of the Destination Disengagement (and user fraction) Time. The mean Destination

Disengagement Time for the two set oftests were only 0.002 seconds apart. They are not considered

to come from the same population however, due to the very small precision window obtained for the

tests (0.001 s for the PEP and 0.004 s for the FEP). However, due to the small numerical difference

between the parameter estimates, it was determined that additional testing would not provide any

more information.

In one of the last modem tests performed, 8 consecutive bits were lost (test number 5711). This was

the only time the received data differed from the transmitted data.

significant digits (i.e., the PEP User Information Bit Transfer Rate's 95th lower confidence limit,

the mean and the 95th upper confidence limit all equal 0.1039E+5). If more digits were listed, the

absolute precision would be between 0 and 5 bps. The precision for the FEP test is also 5 bps.

the PEP tests was 0.003 seconds and the precision for the FEP tests was 0.017 seconds. The mean

for the two test series were just 0.05 seconds apart. Due to the small numerical difference between

the parameter estimates, it was determined that additional testing would not provide any more

information.

The Access Time was also unable to be pooled. For this parameter, it was not due to a small

precision window. For the ISDN service, the Access Times can be grouped into three sets as shown

in Table 10. The first set is for the PEP tests. The mean Access Times for the PEP tests range from

23.367 seconds to 23.712 seconds. The mean ofthe five test means was 23.48 seconds. The second

set is for the PEP tests when the packet router is turned OFF. The mean Access Times for the FEP,

with the packet router OFF, ranged from 26.866 seconds to 27.346 seconds. The mean of the four

test means was 27.03 seconds. The third set is for the FEP tests when the packet router is turned

ON. The mean Access Times for the PEP, with the packet router ON, ranged from 24.511 seconds

to 24.776 seconds. The mean of the five test means was 24.62 seconds.

42
The packet router is nonnally only used in X.25 communications. However, for ISDN

communications, the D-channel uses the packet router, when available (i.e., when it is turned ON),

for call setup. When the packet router is not available, call setup is perfonned using the ACTS

orderwires. Original estimates were that the packet router would reduce the call setup time by 1.5

to 3 seconds. Comparing the Access Time mean for the FEP with the packet router OFF, 27.03

seconds, and the mean for the PEP with the packet router ON, 24.62 seconds, results in a call setup

improvement of 2.41 seconds. The observed improvement agrees with what was anticipated.

As stated previously, Table 9b shows that the Access Time measured in the PEP and FEP (with the

packet router OFF) tests came from two separate populations. The packet router remained OFF

during the PEP tests though. I I However, comparing the Access Times of the PEP tests to the FEP

with the packet router OFF shows a difference of 3.5 seconds. After the conclusion of the tests, it

was discovered that the ISDN tenninal adapter was set to answer on the second ring for the FEP.

The tennina1 adapter was set to answer after the first ring for the PEP tests. The change occurred

during the shipment/setup of the equipment in Cleveland. Therefore, for ISDN service with the

packet router OFF, the mean Access Time and precision that should be used is 23.48 ± 0.10 seconds

as shown in Table 3d.

4.2 Discussion of Results and Tests

The major result from the PEP and PEP tests was that even though the tests were perfonned between

different cities, at different times of the year (PEP tests mainly perfonned in the spring/summer and

FEP tests mainly perfonned in the fall/winter), and under the prevailing traffic conditions (which

were dependent on the number of other experimenters using the satellite), much of the data could

still be pooled. This implies that the data came from the same population. Therefore, even though

the tests were only perfonned between two city sets, the results can be considered valid for other

locations operating under similar conditions.

A surprising result was that the X.25 via packet service throughput perfonnance did not improve as

expected in Section 3.2 when the tests were run between two separate locations. Designers of the

ISDN SP thought the perfonnance would improve when the remote packet handler was implemented

in a different computer from the local packet handler. This was not observed in these tests. The PEP

11 The packet router was not functional until mid-November, 1994 and the ISDN service PEP tests were

performed in mid- to late-October of that year.

43
tests, performed in a loopback mode in Boulder, and the FEP tests, performed between Boulder and

Cleveland, resulted in the same throughput value of 10.4 kbps.

In addition, the throughput was much less than the originally expected 64 kbps. The ISDN SP

designers mentioned that they measured the throughput at approximately 20 kbps (still less than the

originally anticipated 64 kbps) with a block size of 128 bytes. Several tests were run at ITS to

understand this difference in measured throughput. Our tests found that when the total data block

transferred was smaller than 4096 bytes, the measured throughput was approximately 20 kbps.

However, when the data block size exceeds 4096 bytes, as in our tests, the measured throughput

dropped to approximately 10 kbps. This finding suggests the existence of a 4096-byte buffer

somewhere in the system. This is currently being investigated to determine the location of this

buffer.

A final observation was that the BER performance of the system was extremely good. All the tests

except for one resulted in clean data transfer; eight consecutive bits were lost in one test. These

results are consistent with BER measurements NASA has taken for the ITS ES. NASA runs BER

tests for each TI-VSAT in the network when the satellite is operating in baseband processor mode

(the necessary mode for TI-VSAT operation). For the ITS ES, the BER tests have demonstrated

longterm error-free operation.

4.3 Problems and Recommendations for Test Set Improvement

One of the main problems experienced during the testing period was that tests would sometimes fail

halfway through a test due to the computer system and not be able to recover. This occurred most

often during an Access/Disengagement test; the serial port would lock up and could only be

corrected by rebooting the system. It would not have been correct to count all the remaining tests

as Access Denials or Access Outages since the problem had nothing to do with the network or user;

it had to do with the test set itself.

Another problem experienced was the limit on the amount of data that could be transferred for each

test. Data had to be limited for two reasons. First, an increase in the amount of data taken increases

the amount of time needed to reduce/analyze the data. Due to the algorithms used to detect lost,

errored, or extra bits, a relatively small increase in the transmitted data size results in a larger

increase in data reduction time. Second, the data had to be stored. The collection of 1.6 Mb of data

for each of 60 tests (five tests per service for 4 services for the test set characterization, the PEP tests,

44
and the PEP tests) adds up to 96 Mb of stored data. Ifthe amount of data per test is increased much

beyond this level, the amount of data to control becomes unruly.

Since the amount of data to be transferred was on the order of megabits, and not tens or hundreds

of megabits, it was impossible to measure the ACTS Bit Error/Loss/Extra Probability with the

desired accuracy. NASA took BER measurements consistently on two channels for each ES. They

restarted the BER measurement every 10 minutes and recorded the measured BER at the end of the

10 minutes. In 10 minutes, 76.8 Mb get transferred in two channels. Therefore, assuming a half of

an errored bit (so the error is not seen) during the 10 minute test, the measured BER would be

6.5 x 10-9

• A typical example of a 24-hour plot for ES #9 (the ITS site), on both the uplink and

downlink, is shown in Figure 15 . As this plot shows, no errors were received during the testing

period. 12 Therefore, the actual BER of the ACTS system under normal conditions is very low and

performing tests using 1.6 Mb of data, even for 50 trials, does not suffice to determine the system's

performance.

A solution to both of these problems would be to operate the tests in real time and to calculate the

results cumulatively rather than just at the end of the test. With such a system, the tests could be

kept running the whole time the system under test is active so that an access denial (which may be

days or weeks between occurrences) or bit error outcomes (which may be hours or days between

occurrences) could be "caught."

One last problem identified was that the software was originally designed to only work with serial

ports. In order to use the X3.l4l testing system with the X.25 protocol, the software had to be

changed to accommodate the X.25 API. This required extensive changes and should not have been

required - especially if the goal is for any user, even one that does not know the test software

intimately, to be able to use the system to test their data communication network. Ideally, the system

should be flexible enough to accommodate an unlimited number of software (e.g., APIs) and

hardware interfaces. If such a system were built, the interfaces that are available today would not

limit the system at some future time when different interfaces are then available. In summary, at

some point, an effort needs to be undertaken to start from scratch and make the system interfaceindependent.

12 During the period from 1400 to 2330 hours, NASA was not taking BER measurements for this TlVSAT. The symbols at 2010 and 2250 hours show that the Tl-VSAT requested to be shut down and then

reacquired at those times.

APPENDIX A

This appendix contains the test set characterization result summaries. Each test was run five times

and the combined results are analyzed in Section 2.

Table Al shows the test number and a description of the test. 13 The following pages are arranged

as follows: modem service tests first, X.25 via circuit service tests next, and the ISDN service tests

last. The test summaries contain information to identify the test, an assessment summary, the

measured performance parameter values (mean values over all the trials), and reduction

specifications (i.e., the specified values used). In addition, for the User Information Transfer tests,

a correlation summary and specifications are included.

The specified values used to determine the test set characterization parameter values were set low

enough so that all data would be used to determine the mean values. This was especially important

for the Preliminary Characterization·Tests so that the measured mean values included all the

measurements (and are not biased by omitting some of the poorer test results). This mean value was

used in the Full Characterization Tests to define the specified values.

13 In the table, AID stands for Access/Disengagement and CKT stands for circuit.

APPENDIXB

This appendix contains the preliminary characterization test result summaries. Each test was run

five times and the combined results are analyzed in Section 3.

Table B1 shows the test number and a description of the test. 14 The following pages are arranged

as follows: modem service tests first, X.25 via circuit service tests second, X.25 via packet service

tests third, and the ISDN service tests last. The test summaries contain information to identify the

test, an assessment summary, the measured performance parameter values (mean values over all

the trials), and reduction specifications (i.e., the specified values used). In addition, for the User

Information Transfer tests, a correlation summary and specifications are included.

The specified values used to determine the preliminary characterization parameter values were set

low enough so that all data would be used to determine the mean values. The specified values used

are the same as used for the test set characterization. The specified values were set so that no data

would be excluded in determining the measured mean value of the performance parameters. These

measured mean values were used as the specified values in the full characterization tests.

14 In the table, AID stands for AccesslDisengagement, CKT stands for circuit, and PKT stands for packet.

The symbol "--" in the "Measured BER" column means that during these tests, BER measurements were not

recorded.

14. SUPPLEMENTARY NOTES

15. ABSTRACT (A 200-word or less factual summary of most significant information. If document includes a significant bibliography or literature

survey, menlion it here.)

The results of a series of data communication tests, which define the digital

end-to-end performance of the Advanced Communication Technology Satellite (ACTS),

are presented. The experiment consisted of a test set characterization to

determine the effect of the test set on the results, a preliminary characterization to define the failure/non-performance outcome thresholds, and a full

characterization. The experiments' design, execution, and analysis comply with

the American National Standards X3.102 and X3.141. The tests showed that ACTS

has a very clean data channel (only one lost byte was recorded during all the

tests), the X.25 packet mode did not perform as well as expected, and the

parameter estimates did not vary substantially over time or destination location.
