Problems solved by technology

[0013] Although the above method can solve the problems that may occur between cross-ring nodes, this method is because the convergence speed of STP and RSTP is relatively slow. Even RSTP can only reach the level of convergence rate in seconds, which prolongs the network communication time and aggravates the problem. network traffic load

Embodiment Construction

[0045] The core idea of ​​the present invention is based on the establishment of a protection group in the PRP bridge-ring network equipment to generate a device state control message, so that the equipment in the PRP bridge-ring network can control the message according to the device state. A redundant protection method for the PRP bridge-ring network is established for the process of searching and competing for the Master (primary) state of the device and the recovery of the connection between the devices in the Master state in the non-communication.

[0046] In the present invention, it is necessary to determine the multiple devices located on two RPR bridge rings at the same time, and set up a corresponding protection group. The protection group is composed of devices in the PRP bridge ring network. on the bridge ring. The device in the protection group is set to have two states: Master state and Slave (standby) state, and each protection group has its own group ID, device...

Abstract

The method comprises: setting one of multi devices simultaneously located on the bridge between two RPRs (resilient packet ring) as an active device and other devices are set as standby devices; making interaction of device state control messages between active and standby devices to implement the redundancy protection of RPR bridge. By the invention, the switch speed from one failure cross-ring bridge device to other standby devices can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing RPR bridge redundancy protection. Background technique [0002] With the emergence of various new-generation metropolitan area network technologies, RPR (Resilient Packet Ring) technology is becoming more and more important for the metropolitan area network due to its advanced technology, effective investment, superior performance, and diversity of supported services. Use more. Resilient packet data ring RPR technology is a new network architecture and technology designed to meet the requirements of packet-based metropolitan area network; it is a ring network composed of packet switching nodes, and adjacent nodes are connected by a pair of optical fibers; its network The topology is based on two rings transmitting in opposite directions. [0003] RPR has many technical features, including: [0004] 1. Effective multiplexing of transmission ...
