In the traditional IP network, all packets are treated equally without distinction. Each network
device uses first in first out strategy for packet processing. The best-effort network sends packets to
the destination, but it cannot guarantee transmission reliability and delay.
QoS can control network traffic, avoid and manage network congestion, and reduce packet
dropping rate. Some applications bring convenience to users, but they also take up a lot of network
bandwidth. To ensure all LAN users can normally get access to network resources, IP traffic control
function can limit the flow of specified host on local network.
QoS provides users with dedicated bandwidth and different service quality for different
applications, greatly improving the network service capabilities. Users can meet various
requirements of different applications like guaranteeing low latency of time-sensitive business and
bandwidth of multimedia services.
QoS can guarantee high priority data frames receiving, accelerate high-priority data frame
transmission, and ensure that critical services are unaffected by network congestion. IR900 supports
four service levels, which can be identified by receiving port of data frame, Tag priority and IP
priority.
