Ethernet-tree realization method, system, device and network equipment

Abstract

The invention discloses an Ethernet-tree realization method, an Ethernet-tree realization system, an Ethernet-tree realization device and network equipment. The method comprises that: a first provider edge (PE) transmits a reachable route updating message carrying the node type of a first connected customer edge (CE) to a second PE, wherein the node type comprises a leaf node and a root node; andwhen receiving the route updating message, the second PE judges whether the first CE is the leaf node or the root node according to the node type carried in the route updating message, traverses eachsecond CE connected with the second PE, and for each second CE, does not establish a pseudo wire between the first and second CEs between the second PE and the first PE if the first and second CEs are both the leaf nodes, otherwise tries to establish the pseudo wire between the first and second CEs between the second PE and the first PE. The node type is announced by the route updating message, and the leaf nodes are isolated so as to avoid the establishment of the pseudo wire between the leaf nodes and simply and conveniently realize an Ethernet-tree.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a virtual private local area network-based Ethernet-based multipoint service realization method, system, device and network equipment. Background technique [0002] Metro Ethernet Forum (MEF) 10.1 and MEF6.1 define three Ethernet services: point-to-point Ethernet line (E-line, Ethernet line), multipoint-to-multipoint Ethernet local area network (E-LAN, Ethernet LAN) And point-to-multipoint basic multipoint service (E-tree, Ethernet Tree). E-TREE is a hybrid technology of E-LAN ​​and E-LINE: in an E-TREE instance, there may be either a multipoint-to-multipoint (E-LAN) connection or a point-to-point (E-LINE) connection. From this point of view, E-LAN ​​is a special E-TREE, all of its nodes are root nodes, and there is no communication limitation. [0003] E-TREE technology can provide users with Internet access, Internet Protocol Television (IPTV), mobile signal tun...
