Problems solved by technology

It can be seen from this that when the broadcast / multicast service is transmitted in the two-way broadcast / multicast mode, the broadcast or multicast message will occupy the upper ring bandwidth of the two rings at the same time, so that the access bandwidth of the node will decrease. Reduce the bandwidth of this node to transmit other services
Therefore, the two-way broadcast / multicast mode is not suitable for use when the RPR ring network is normal

Embodiment Construction

[0046] The method and device of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0047] In order to avoid the lack of services or the waste of bandwidth in the one-way broadcast / multicast mode, and to solve the problem of occupying a large POP bandwidth in the two-way broadcast / multicast mode, the present invention provides an RPR ring The method of implementing broadcast or multicast services on the Internet, the main idea is: combine the one-way broadcast / multicast mode and the two-way broadcast / multicast mode, and use the one-way broadcast / multicast mode when the RPR ring network is working normally Realize the broadcast or multicast service, guarantee the access bandwidth of each node on the RPR; and when the RPR ring network fails, use the two-way broadcast / multicast mode to realize the broadcast or multicast service, thereby avoiding the lack of service and bandwidth...

Abstract

The method comprises: when transmitting a broadcast or multicast service, the source node of said broadcast or multicast service decides if its own resilient packet ring works normally; if yes, then using the single-direction broadcast / multicast way transmit said broadcast or multicast service; otherwise, in term of the switch information of said resilient packet ring, using bidirectional broadcast / multicast way transmit said broadcast / multicast service. The apparatus thereof comprises a network topology discovery and protection module and a broadcast / multicast controller; wherein said network topology discovery and protection module controls said broadcast / multicast controller to select one mode from both said broadcast and multicast modes.

Description

technical field [0001] The present invention relates to a resilient packet ring (RPR, Resilient Packing Ring) technology, in particular to a method for realizing broadcast or multicast services on the RPR and a device for realizing the method. Background technique [0002] RPR technology is a new type of media access control (MAC) layer technology that can optimize data transmission on a ring topology network. Using this technology can also effectively transmit data, voice, image and other types of services. It combines the economical, flexible and scalable characteristics of Ethernet technology, and absorbs the advantages of fast protection of Synchronous Digital Hierarchy (SDH) ring network, and also has automatic network topology discovery, ring bandwidth sharing, fair distribution, Technical advantages such as strict business classification (COS). The main goal of the RPR technology is to provide a more cost-effective metropolitan area network solution without reducing ...
