1. General Description of DApps-TAP
For NuDOG-101T, NuDOG-801 and NuDOG-301C, all data streams between two network ports can be
duplicated and sent to PC via mini USB port for monitoring and analyzing. Users can specify conditions tofilter the packets wanted by DApps-TAP application software. It reduces USB port’s network traffic and also
cuts down PC resource consumption while dealing with large quantity of packets.
DApps-TAP is designed for Xtramus Technologies NuDOG series handheld Ethernet testing devices listed
in the table down below:

2. NuDOG-301C Descriptions
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, RFC 2889, and QoS. With these utilities,
NuDOG-301C is able to conduct throughput test, latency test, error filtering test, forwarding test, and soon. Utility software can provide a user-friendly interface for different test configurations when setting test
parameters and criteria. 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.

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.

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).

If you choose the TAP mode on
Loopback interface, the NuDOG-301C,
NuDOG-801 and NuDOG-101T
operates like a hardware device thatprovides a method to access andmonitor the data streams flowing across
two network ports without intruding therunning network.

If you choose the Layer 1 Loopback
Mode on Loopback interface, the
NuDOG-301C, NuDOG-801 and
NuDOG-101T filters out broadcast,multicast and null DA (destination
address) packets of incoming data
streams, and then resends them back tothe same connected port.

If you choose the Layer 2 Loopback
Mode on Loopback interface, the
NuDOG-301C, NuDOG-801 and
NuDOG-101T filters out broadcast,multicast and null DA (destination
address) packets of incoming data
streams, and then resends them back tothe same connected port with swapped
DA / SA (destination / source MAC
address) and recalculated CRC.

If you choose the Single-End Mode on
Loopback interface, the selected ports
are idle that all transmitting and/or
receiving data streams via these ports
are disabled.

8. Appendix – Other Utility Softwares for NuDOG-301C/801/101T
There are several other optional utility softwares for NuDOG-301C/801/101T for different kinds of test
requirements. The following section contains brief descriptions of these utility softwares.
DApps-2544: Test Suite Based on RFC-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-Backof Ethernet switches or routers via this device. The real-time test results display and customized reportprovides an effective way when examining the DUT.
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-301/NuDOG-801/NuDOG-101T has a mini-USB port for PC connection. In addition to network
TAP, system control and system upgrade functions. NuDOG-301/NuDOG-801/NuDOG-101T can also be
used as a network interface card. With control software and NuDOG-301/NuDOG-801/NuDOG-101T’s
hardware conversion, network data streams can flow between NuDOG-301C/NuDOG-801/NuDOG-101T’s
USB and network port.
DApps-2889: Test Suite 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 2544.
DApps-MPT: Automatic batch tests for Ethernet device
DApps-MPT is an accurate and efficient software suite for mass-production scale test or batch network test.
Various packet generation and reception testing items could be configured to pre-defined testing modes.
The utility of DApps-MPT can load testing models easily. All simple and visualized results and detailed
testing logs are available to access upon demand. DApps-MPT is a powerful and convenient tool to applyon this device.
