Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0037] The embodiment of the present invention provides a kind of method that realizes the root-to-multipoint (E-Tree) service based on virtual private local area network service (VPLS), and the method comprises:

[0038] Step 1, the node automatically generates or accepts the virtual local area network identification (VLAN ID) for identifying that the data message is from the root access link (AC) or the leaf AC in the VPLS domain fixedly distributed by the standard organization;

[0039] Among them, there are two ways to use the VLAN ID to identify whether the packet is fro...

Abstract

The present invention provides a kind of method and node that realize the E-tree service based on VPLS, and the method comprises: the node automatically generates or accepts the VPLS domain that the standard organization fixedly distributes and is used for identifying that the data message comes from the root access link (AC) or the virtual local area network identifier (VLAN ID) of the leaf AC; the node determines the AC attribute for sending the data message, and stamps the data message with the VLAN ID of the AC attribute and sends it. The method and nodes for realizing the VPLS-based E-tree service above solve the complicated and time-consuming problem of manual configuration of ROOT and Leaf VLAN IDs; and the implementation is simple, the changes to the existing protocols are small, and the implementation cost is low.

Description

technical field [0001] The present invention relates to Ethernet Tree (Ethernet Tree, E-tree for short) technology, in particular to a method and node for realizing E-tree service based on Virtual Private Lan Service (VPLS for short). Background technique [0002] The Metro Ethernet Forum (MEF) defines two types of multipoint Ethernet services: a multipoint-to-multipoint (E-LAN) service and a root-to-multipoint (rooted multipoint, E-Tree) service. The difference between these two services is that all nodes of E-LAN ​​can communicate with each other without any restrictions; while E-Tree has two types of nodes, Root and Leaf. They cannot communicate with each other. For details, please refer to MEF6.1 and MEF10.2. [0003] The Virtual Private Lan Service (VPLS) defined by the Layer 2 Virtual Private Networks (L2VPN) Working Group of the Internet Engineering Task Force (IETF for short) is an IP / In the multi-protocol label switching (MPLS) network, multi-point to multi-point...
