The ability to distinguish business types is the prerequisite to provide corresponding
services, so the traditional best-effort service no longer meets the application needs.
Therefore, QoS comes into being. It regulates the network flow to avoid and handle
network congestion and reduce packet loss rate. Meanwhile, users can enjoy
dedicated bandwidths while business can improve service quality, thus perfecting the
network service capacity.
QoS priorities vary with message types. For instance, the VLAN message uses 802.1p,
also known as the CoS (Class of Service) field, while the IP message uses DSCP. To
maintain the priority, these fields need to be mapped at the gateway connected with
various networks when messages flow through the network.
802.1p priority in the VLAN frame header
Typically, VLAN frames are interacted between Layer 2 devices. The PRI field (i.e.
802.1p priority), or CoS field, in the VLAN frame header identifies the quality of service
requirements according to the definitions in IEEE 802.1Q.
802.1p priority in the VLAN frame
The 802.1Q header contains 3-bit PRI fields. PRI field defines 8 CoS of business
priority ranging from 7 to 0 from high to low.
