1. NuApps-QoS-RM 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. NuApps-QoS-RM 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.
NuApps-QoS-RM is designed for Xtramus Technologies XM-RM series module cards listed in the table
down below:

4.9.1. Pairing/Assigning Test Ports
Before making any test configurations on the Test Configuration screen, you have to make the proper
port pairing/assigning first. NuApps-QoS-RM has 2 different test modes available: One-One and Many-
Many.
To access these 2 test modes, please click the scroll-down menu located on the upper-right part of
NuApps-QoS-RM’s window as shown in the figure down below.
Also, set the direction of source port to destination port by clicking the scroll-down menu located
down part of the scroll where you chose the One-One and Many-Many mode.
If you want to reset all settings you’ve done for NuApps-QoS-RM’s test mode back to the default value,
please press the Reset button located next to the scroll-down menu.
Please see the sections down below for more information regarding to pair/assign ports in different test
modes.

One-One
In One to One test mode, packets will be sent from one source port (A) to one destination port (B) as
shown in the figure above.
Port Pairing/Assigning for One-One Mode
1. Choose a port that will serve as the source
port from the Source Ports field.
2. Choose a port that will serve as the
destination port from the Destination Ports
field.
3. Click the > button to add the port pair you
set in step1-2.
Note: If you click the >> button, the system will
automatically match all the available ports into
pair.
