Implementation method and switching device of multi-point to multi-point service

Abstract

This invention provides one point to point business realization method and exchange device, which sets relative set broadcast address for business sample and uses set broadcast address to convert itsmechanism into set mechanism for effective control of broadcast generation, wherein, this invention uses set broadcast address to realize MP2MP business to avoid linkage fault by tree agreement and tolimit the fault impact into the data message by the linkage.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multipoint-to-multipoint service realization method and switching equipment. Background technique [0002] MP2MP (Multipoint to Multipoint) service is an important service type in the telecommunication network. At present, there are mainly two methods for implementing MP2MP services based on Ethernet: [0003] Method 1. First, use the traditional Ethernet bridge mechanism to connect each node, and then use the self-learning method of the Ethernet bridge to establish forwarding entries in each Ethernet bridge. In order to avoid broadcast storms, the Ethernet uses The spanning tree protocol obtains an effective tree-shaped network topology by blocking some links in the Ethernet. The tree network topology with node A as the root is as attached figure 1 as shown, figure 1 In , two nodes of node E are blocked to avoid broadcast storm. The Ethernet bridge transmits...

Problems solved by technology

[0008] Although the MPLS tunnel technology can guarantee the service quality, when the Ethernet service is carried on the H-VPLS architecture, the PE-rs needs to find the corresponding MPLS tunnel according to the MAC address of the service, so that the PE-rs in the MPLS VPLS need to The user's MAC address is reserved, which ultimately affects the scalability of the network
