RPR address binding method

Abstract

The invention discloses an elastic sectionalization ring address binding method in the network transmission technological domain, which is characterized by the following: realizing the binding of RRP ring node MAC address and IP address through ATD frame in the extended RPR protocol; without adding extra system resource consumption; converging rapidly for topology after the RPR looped network occurs switching; providing address binding information for over three layered report to transfer and utilize.

Description

technical field [0001] The invention relates to the transmission network technology, in particular to the elastic grouping ring technology in the transmission network. 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. The Resilient Packet Ring ("RPR") technology is a new type of Medium Access Control ("MAC") layer protocol that optimizes data service transmission on a ring structure. It absorbs the Ethernet ( Ethernet) economy and synchronous digital system (Synchronous Optical Network, referred to as "SDH") system 50 milliseconds (ms) ring protection characteristics, constructed a two-layer network suitable for Ethernet data transmission, can provide on the existing optical network with Quality of Service ("QoS") management and high-efficiency data servi...

Problems solved by technology

[0018] In practical application, the above-mentioned solution has the following problems: the implementation of the existing technical solution is complicated, additional network bandwidth and RPR processing resources are required, and after the switchover of the RPR ring network, the topology convergence speed is slow

[0019] The main reason for this situation is that the existing technical solutions need to communicate between the ARP protocol and the RPR protocol. After the ARP protocol learns the correspondence between MAC and IP, it needs to notify the RPR protocol. content, update the RPR encapsulation information of the ARP adjacency table, which increases the complexity of the protocol, and the implementation is more complicated. At the same time, when the nodes of the RPR ring learn the correspondence between MAC and IP, certain bandwidth resources are required for inter-node communication, which requires loss Additional link bandwidth. In addition, because the existing technical solution is a process of dynamic establishment and learning, after the switchover of the RPR ring network, the topology convergence speed is slow, and some additional RPR processing resources are required
