Precise Recognition of MPLS L2VPN QoS
Pin Feng · Communications technology · 2015
With the wide application of MPLS VPN technology in enterprise network,an even higher requirement on the Qo S of VPN is proposed.Precise recognition of MPLS L2 VPN Qo S is adopted in the PE side,thus to implement in-depth analysis on the user L2 VPN data packets and extract key information from the OSI seven-layer protocol,so as to get the message priority,and realize network monitoring,flow control and other functions.Actual application indicates that precise recognition method of MPLS L2 VPN Qo S could identify various of business flows of the existing network,and with respectively different Qo S rules could isolate each business system and efficiently integrate enterprise's external and internal information networks,thus to ensure the safe and stable operation of power network.
