Problems solved by technology

When the number of configured protection pairs is small, this processing method can generally meet the fault recovery requirement of 50ms. However, once the number of configured protection pairs is large, such as hundreds or thousands of pairs, a large number of faults are reported instantaneously, which will cause the CPU to If it is extremely busy, the switching performance will be greatly reduced, causing many protection pairs to fail to meet the 50ms switching requirement
In addition, because the CPU has been dealing with these faults, sometimes it has no time to take care of the processing of other business, protocol and other messages, which will lead to some new problems

Abstract

This paper discloses a device and method for implementing linear protection switching, which are applied to devices configured with protection groups; the device for implementing the device includes: a fault detection chip, which is used to generate a management message after detecting a link fault in the protection group, and Sending a management message to the service forwarding chip; the service forwarding chip is used to set the switching identification value of the protection group according to the received management message. The device and method for implementing linear protection switching provided in this paper can realize the function of fast switching of services at the hardware layer, thereby improving the performance of protection switching and enhancing the stability of equipment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and method for realizing linear protection switching. Background technique [0002] With the vigorous development of "Internet +" advocated by the country, brand-new concepts have been proposed one by one, such as: Internet finance, intelligent transportation, smart home, big data, cloud computing, Internet of Things, etc., and the communication market has encountered unprecedented development opportunities. However, new challenges have also been encountered. The market has an urgent demand for large-capacity, high-bandwidth, high-quality, and high-security networks, and the requirements for rapid recovery from network failures are getting higher and higher, especially in financial, national defense, and security departments. It is even more required that the network failure can meet the requirement of carrier-level switching (fault recovery within 50 milliseconds...
