Embodiment Construction

[0038] The present invention proposes a message processing method in a VPLS network. When a PE maintains the MAC address of the CE side in the MAC address forwarding table of its own VSI, if it detects a message from the PW whose destination MAC address is the MAC address For the first packet, actively return a unicast packet with the source MAC address as the MAC address to the PW, so that the PE at the peer end of the PW can quickly learn the MAC address without passively waiting for the packet sent by the second user to arrive at itself The MAC address is learned later, thereby changing the flooding of unknown unicast messages into unicast forwarding of known unicast messages, reducing the traffic generated by the flooding of unknown unicast messages in the VPLS network, and achieving network bandwidth saving purpose of the resource. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

Abstract

The invention provides a method for message processing in VPLS service network and a device. In the method, if monitoring a first message which comes form PW and has a target MAC address of a second MAC address, PE actively returns a unicast message whose MAC original address is a second MAC address to PW, so that PE on the opposite terminal of PW can quickly learn the second MAC address; thus, flow produced during flooding treatment to the unicast message in the VPLS network is greatly lowered so as to save network bandwidth resource.

Description

technical field [0001] The present invention relates to the field of virtual private local area network service (VPLS, Virtual Private LAN Service) network technology, in particular to a method for message processing in a VPLS network and service provider edge network equipment (PE, Provider Edge). Background technique [0002] VPLS is also called Transparent LAN Service (TLS, Transparent LAN Service) or Virtual Private Switched Network Service (Virtual Private Switched Network Service), which is a point-to-multipoint Layer 2 (data link road layer) virtual private network (VPN, Virtual Private Network) business. In the VPLS network, user sites are connected by a multi-point network, which is different from the point-to-point (P2P, Point to Point) connection service provided by the traditional VPN. VPLS actually leases a series of virtual switches created on PEs to users. The networking of virtual switches is exactly the same as that of traditional switches. In this way, us...
