Embodiment Construction

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly expressed, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The core idea of ​​the technical scheme of the present invention is: set the user node and the main and standby service nodes through which the business passes on the elastic packet ring to generate the corresponding service forwarding mapping table; when the main service node fails, the user node reads the service forwarding mapping table In the information of the standby service node corresponding to the service, the service is automatically switched from the main path to the standby path; when the fault of the main service node is eliminated, the user node also reads the information of the main service node corresponding to the service in the table, and changes The service is automatically restored from the backup pa...

Abstract

The invention relates to elastic group ring technology; particularly disclose the provision of a business protection method on the elastic group ring. The method comprises the following steps: according to the business needs, set users node the business pass through and host,emergency business node on the elastic group ring, create the business retransmission mapping table from users node message and host,emergency business node message and saved in the said users node; when the users node topology detect the failure of main service node, transmit the mapping table through all the saved business, read the service nodes information corresponding to the business, automatically switch the business from the main path corresponding to main service nodes to emergency path corresponding to the emergency service node. The invention achieves double or multi attaching protection of supporting business on the elastic group ring; shorten the automatic switching or restore time, improves its efficiency and reliability.

Description

Technical field [0001] The present invention relates to RPR (Resilient Packing Ring, Resilient Packing Ring) technology, in particular to a method for realizing service protection on RPR. Background technique [0002] With the rapid increase in the demand for data services, the requirements for packet multiplexing, bandwidth management, protection, security and networking of data services are getting higher and higher. RPR technology is a new transmission technology that can be used to optimize the bandwidth management of the ring network, simplify the deployment of data services, provide flexible packet multiplexing and ring network bandwidth protection, and has greater advantages in the ring network. , MSTP (Multi-Service Transport Platform, Multi-Service Transport Platform) and NGTP (Next Generation Transport Platform, Next Generation Transport Platform) equipment is widely used. [0003] RPR technology is an optional technology at the data link layer (L2 layer), which is suit...
