Protection switching method and system

Abstract

The invention discloses a protection switching method and system. An agent center is respectively arranged in a master microwave node device and a slave microwave node device which constitute a protection pair, and a management center is arranged in the protection pair. The method comprises the steps of: determining that one or more failures occur on the master microwave node device or the slave microwave node device by a master microwave node device agent center and a slave microwave node device agent center according to a preset multi-point failure detection policy; performing the protection switching of the master microwave node device and the slave microwave node device through a protection switching communication channel by the master microwave node device agent center and the slave microwave node device agent center when the communication between the master microwave node device and the slave microwave node device is normal; and informing the management center by the master microwave node device agent center and the slave microwave node device agent center when the communication between the master microwave node device and the slave microwave node device is abnormal, and performing the forced protection switching of the master microwave node device and the slave microwave node device through the protection switching communication channel by the management center. With the technical scheme of the invention, the protection switching is more reliable and safer, the time for protection switching is reduced, and the performance of the devices is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a protection switching method and system. Background technique [0002] At present, microwave communication technology has been available for more than half a century. This technology is a wireless communication method for information transmission through ground line-of-sight in the microwave frequency band. Microwave communication plays a pivotal role in the field of communication and is a fast means of communication. No matter in the mobile access network, or in the mobile metro network and core network, microwave equipment can be seen everywhere, especially in emergency communication, microwave is an irreplaceable means. Digital microwave communication, optical fiber, and satellite are called the three pillars of modern communication transmission. [0003] As a single microwave device, it must be able to work stably and reliably to support a stable and reliable microwave network. H...
