1. DApps-QoS Overview
Network QoS (quality of service) is a way to classify the transmission priority of packets while
the volume of to-be-transmitted packets is beyond the Ethernet switch or router’s throughput
capability. Packets with higher priorities are processed and transmitted first. For Ethernet
frame, each packets can be tagged with a VLAN ID and CoS (class of service), and Layer 3 IP/UDP
packets are marked according to the type of service they need. For Ethernet switch or router that supports
QoS, packets higher CoS priority should be transmitted first if network traffic is congested. DApps-QoS can
limit acceptable network traffic at receiving port, analyze the traffic distribution of packets with different
priority received from router or switch, and test the performance of Layer 3 Router, Switch with QoS
function.
DApps-QoS is designed for Xtramus Technologies NuDOG series handheld Ethernet testing devices listed
in the table down below:
Devices Supporting DApps-QoS
NuDOG-301C
NuDOG-801
NuDOG-101T
Also, please make sure that your PC meets the requirements listed in the table down below before
installing DApps-2889-RM.

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 software
that qualify industrial standards such as RFC 2889, RFC 2544, and QoS. With these utilities,
NuDOG-301C is able 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 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-field
troubleshooting.

2.2. Features & Advantages of NuDOG-301C
Hardware based wirespeed streams generation, analysis, network TAP and NIC
High precision performance for measuring throughput, latency, packet loss and disordered sequence
Wirespeed traffic capturing with programmable filter and trigger criteria
Supports Universal Stream Counter (USC) with 128 streams
RFC 2544 test suite
RFC 2889 test suite
Layer 1 and Layer 2 loopback test
High precision 1 ppm temperature-compensated oscillator provides accurate clock speed to ensure
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 meets
various 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.

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 of
monitoring 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 Mode
In this mode, NuDOG-301C simulates network interface card (NIC).
