Embodiment Construction

[0042] The specific implementation manners of an E-tree service message forwarding method, device, and equipment provided by the embodiments of the present invention will be described below in conjunction with the drawings in the description.

[0043] For cross-PE forwarding of E-Tree service packets in a VPLS network, each PE may be used as an ingress PE or an egress PE: In the case where the PE is connected to the PE in the same operator network and sends it to the CE connected to the other PE in the same operator network, the PE is the ingress PE; when the PE is connected to the destination CE and receives the message from other PE in the same operator network In the case of forwarding the text to the destination CE, the PE is an egress PE at this time.

[0044] For the forwarding process of the E-Tree message across PEs in the VPLS network, it involves the flow of the egress PE and the ingress PE at the same time, but in order to facilitate the description of the E-tree se...

Abstract

The embodiment of the invention provides a method, a device and equipment for forwarding an Ethernet tree (E-tree) service message. A pseudo wire (PW) pair (comprising a first PW and a second PW) is established between provider edges (PE) on the basis of the conventional virtual private LAN service (VPLS) network architecture, the first PW is only used for transmitting messages from a Root node, and the second PW is only used for transmitting messages from Leaf nodes; and the PEs distinguish whether the messages are from the Leaf nodes or the Root node through different PWs. The method, the device and the equipment relate to the technical field of network communication; and the problems about the accurate forwarding of E-tree messages and mutual isolation between the Leaf nodes are solved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an E-tree service message forwarding method, device and equipment. Background technique [0002] Virtual private LAN service (VPLS, Virtual Private LAN Services) is a service that provides a similar local area network (LAN, Local Area Network) on a multi-protocol label switching (MPLS, Multi-Protocol Label Switch) network. Users access the network at the same time from multiple geographically dispersed points, and access each other, just as these points are directly connected to the LAN. Using VPLS, a fully meshed pseudowire (PW, Pseudo Wire) can be established between multiple provider edge devices (PE, Provider Edge), and Layer 2 Ethernet frames can be encapsulated and transmitted between PEs through the MPLS network. Forwarding, so as to establish a point-to-multipoint Ethernet virtual private network (VPN, Virtual Private Network), from the user's point of view...
