System and method for realizing internet set managing protocol on elastic packet ring

Abstract

This invention relates to a data transmission technology in a computer network and discloses a system and a method for realizing Internet set management protocol on an elastic packet ring to realize IGMP in the EVPLAN service provided by RPR ring net, in which, multicast messages can be delivered to definite port multicast set to ensure the security of the network and the effectiveness of bandwidth, which fills in the source RPR node address in the remained field of the response message defined by RFC236, the RPR node studies the multicast address based on the response message to set up a multicast set and an address table for forwarding and filtering multicast service messages.

Description

technical field [0001] The invention relates to the data transmission technology in the computer network, in particular to the multicast message forwarding technology in the elastic packet ring. Background technique [0002] With the increasing popularity of Internet and broadband access, in more and more backbone transmission networks at all levels, data services have gradually surpassed voice services and become the dominant service of the transmission network. Resilient Packet Ring (RPR) absorbs the economy of Ethernet (Ethernet) and the 50 millisecond (ms) ring protection feature of Synchronous Optical Network (SDH) system, and constructs an adaptive The Layer 2 network for Ethernet data transmission can provide Quality of Service (QoS for short) management and high-efficiency data service transmission on the existing optical network, and is the most effective way of Ethernet data service transmission , suitable for data, voice and video applications. RPR technology ad...

Problems solved by technology

[0018] In practical application, the above solution has the following problems: the existing technical solution causes a waste of Ethernet network bandwidth, and the security cannot be guaranteed

[0019] The main reason for this situation is that the existing technical solutions do not implement IGMP protocol multicast on the RPR ring network, and the RPR nodes do not learn the multicast address. The hosts in the host broadcast the received multicast data frames in the Ethernet network connected to them, which causes a waste of Ethernet network bandwidth; at the same time, the broadcast sends the multicast data frames to irrelevant hosts. Therefore, there are hidden dangers in safety, and safety cannot be guaranteed
