1. General Descriptions of DApps-2544
DApps-2544 is a user-friendly and automatic test suite based on industry-standard RFC
2544. It generates and analyzes packets to evaluate the Throughput performances, Latency,
Packet Loss, and Back-to-Back of Ethernet switches or routers via this device. The
real-time test results display and customized report provides an effective way when examining the DUT.

2. NuDOG-301C Description
2.1. NuDOG-301C Overview
NuDOG-301C is a handheld device with two Gigabit ports for
Ethernet testing. The main functions of NuDOG-301C include
multi-streams generation, TAP/Loopback test, and NIC
emulation.
Connecting NuDOG-301C to its mini-USB port makes it
possible for system configurations and managements.
NuDOG-301C is an ideal device for in-field testing.
NuDOG-301C can work along with a series of utility softwarethat qualify industrial standards such as RFC 2544 and RFC 2889. With these utilities, NuDOG-301C isable to conduct throughput test, latency test, error filtering test, forwarding test, and so on. Utility software
can provide a user-friendly interface for different test configurations when setting test parameters andcriteria. More optional software is available for extended test requirements.
With its unique Universal Stream Counter (USC), NuDOG-301C offers real-time statistics of network
events during packet monitoring and capturing.
With these advantageous features, NuDOG-301C is your best partner for LAB researching and in-fieldtroubleshooting.

the reliability of the tests
 Adding errors in transmitted traffic to simulate and test abnormal situations
 Real-time statistics for each port, including transmitted/received frame for VLAN, IPv4, IPv4 fragment,
IPv4 extension, ICMP, ARP, total bytes/packets, CRC, IPCS error and over-and-under size frames
 Utility software with user-friendly interface that supports various parameter configurations and meetsvarious test requirements
 512Mbits wirespeed packet capture buffer per port

2.3. NuDOG-301C Applications in Different Modes
Stream Generation Mode

In Streams Generation mode, NuDOG-301C generates bi-directional network streams for test
requirements as the illustration above.
Both NuDOG-301C's Port A and Port B can generate and receive test streams. The test streams are sent
and returned to the same NuDOG-301C for DUT (device under test) analysis.

6TAP/Loopback Mode

TAP Mode

Loopback Mode
In TAP mode, NuDOG-301C can monitor any data that flows through it. Network TAP is a method ofmonitoring network’s situation dynamically without interference. NuDOG-301C can tap bi-directional or
uni-directional traffic from different sides (port A and port B) and also provides abundant packet counters.
In Loopback mode, NuDOG-301C resends the incoming streams back to the source.
NIC ModeIn this mode, NuDOG-301C simulates network interface card (NIC).

6.1. Hardware Installation
Before starting DApps-2544, your PC and NuDOG-301C/NuDOG-801/802/NuDOG-101T shall beconnected properly. The figure down below illustrates connecting PC and NuDOG-301C. You canconnect NuDOG-801/802 and NuDOG-101T with PC in the same manner, but DO NOT connect
NuDOG-301C or NuDOG-801/802 with PC before the device is powered on.

6.2. Starting DApps-2544
Before starting DApps-2544, the DUT, your PC, and NuDOG-301C/801/802/101T shall be connected asshown in “6.1. Hardware Installation”.
You can start running DApps-2544 by:26



Click Start  Programs  NuStreams
 DApps-2544.



Double-click DApps-2544 icon locatedon your PC’s desktop.

If your PC is not connected with NuDOG-101T/801/802/301C, you can still run DApps-2544 under Demomode. Almost all DApps-2544’s functions are available under Demo Mode. However, please note that
Demo Mode is for system demo purposes only, and does not serve any testing purposes at all.

27

6.3. DApps-2544 Test Modes & Hardware Installation Examples

After starting DApps-2544 as mentioned in the above section, a “Connect to NuDOG” window will pop up.
DApps-2544 supports 3 different test modes: NuDOG Only Mode, End-to-end Mode, and Round-trip
Mode. Please see the section down below for more information and hardware installation examples
regarding to these test modes.
NuDOG Only Mode

Under "NuDOG Only" mode, DUT is connected to NuDOG-301C, which generates packets and sends
them to the DUT for testing.

28

End-to-end Mode

Under "End-to-end" mode, DUT is connected between NuDOG-301C and LB-300. Test packets are sent
between NuDOG-301C and LB-300 in a one-way direction, while the DUT serves as the middle point.
Round-trip Mode

Under "Round-trip" mode, DUT is connected between NuDOG-301C and LB-300. Test packets are sent
between NuDOG-301C and LB-300 in a loop-back manner, while the DUT serves as the middle point.

8. Appendix – Other Utility Softwares for NuDOG series
There are several other optional utility softwares for NuDOG-301C/NuDOG-801/802/NuDOG-101T fordifferent kinds of test requirements. The following section contains brief descriptions of these utility
softwares.
DApps-TAP: Network TAP/Loopback Utility
For NuDOG-301C/NuDOG-801/802/NuDOG-101T, all data streams between two network ports can be
duplicated and sent to PC via mini USB port for monitoring and analyzing. The user can specify conditions
to filter the packets wanted with DApps-TAP application software. It reduces USB port’s network traffic andalso cuts down PC resource consumption while dealing with large quantity of packets.
DApps-SG: Control Suite for Multiple Streams Generator
DApps-SG provides a powerful and sophisticated virtual front control panel to manage this device. Two test
ports can be configured independently with parameters to define multiple streams and capture capabilities.
Traffic for various network protocols can be customized, transmitted, and received on each port.
Comprehensive statistics give users an in-depth analysis of the DUT performance.
DApps-NIC: Network Interface Card Simulation Suite
NuDOG-301C/NuDOG-801/802/NuDOG-101T has a mini-USB port for PC connection. In addition to
network TAP, system control and system upgrade functions.
NuDOG-301C/NuDOG-801/802/NuDOG-101T can also be used as a network interface card. With control
software and NuDOG-301/NuDOG-801/802/NuDOG-101T’s hardware conversion, network data streams
can flow between NuDOG-301C/NuDOG-801/802/NuDOG-101T’s USB and network port.
DApps-2889: Test Suit Based on RFC 2889
DApps-2889 is a user-friendly and automatic test suite based on industry-standard RFC 2889 (partial) to
test the DUT. RFC 2889 provides methodology for benchmarking for local area network (LAN) switching
devices, forwarding performance, congestion control, latency, address handling and filtering. It extends themethodology already defined for benchmarking network interconnecting devices in RFC 2889.
