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

Embodiment Construction

[0048]The core of the multipoint-to-multipoint service realization method and switching equipment of the present invention is to establish the correspondence between the multipoint-to-multipoint MP2MP service and the multicast address in the network, and the node receives the service instance datagram of the MP2MP service When it is determined that the service instance data packet needs to be transmitted using the broadcast mechanism, the data packet of the service instance is transmitted according to the multicast address corresponding to the MP2MP service to which the service instance data packet belongs. It can be seen from the above technical solutions that the present invention transforms the broadcast mechanism into a multicast mechanism, thereby effectively avoiding broadcast storms.

[0049] The technical scheme of the present invention can be applied in Ethernet and also in IP network. In the Ethernet, the foregoing multicast address may be: a multicast MAC address, and i...

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 its mechanism 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 to limit 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 telecommunications networks. Currently, 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. To avoid broadcast storms, Ethernet uses The Spanning Tree Protocol obtains a tree-shaped effective network topology by blocking some links in the Ethernet. The tree-shaped network topology with node A as the root of the tree is shown in FIG. 1. In FIG. 1, two nodes of node E are blocked to avoid broadcast storms. The Ethernet bridge transmits data messages according...
