Xtramus NuApps-QoS-RM V1.1 - Manual (Page 5)

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
