Method and system for equipment switching in communication system

Abstract

This invention discloses a switching method of communication equipment, in addition to a system. It separates the switch controlling function and executive function through dividing controlling module and master and stand-by operation module; the switching flow process comprises several executive steps and conditions, which realize switch flow process controlling and condition migration; it uses the logical address and physics address mapping mechanism to realize the transparent switching of the substratum communication channel; it has the back-up data before and after switching, and has the business smooth dealing mechanism and back-up mode of the master and stand-by veneer; and when happen abnormal thing in switching process, it can realize the switching recovery.

Description

technical field [0001] The invention relates to communication technology, in particular to switching technology in communication equipment. Background technique [0002] Telecommunications networks are required to provide reliable and uninterrupted services to their users, especially in some important business applications, such as electronic money, order processing, customer service, inventory management, e-mail and Internet access, etc., business survivability becomes more important than ever, with availability requirements of 99.999% and beyond. Therefore, the network survivability has become an important factor affecting network design and construction, and the equipment used in the telecommunication network also needs to have high reliability accordingly. [0003] In communication systems, redundant backup and load sharing are commonly used methods to enhance equipment reliability. Redundant backup refers to the use of multiple devices with the same function for repla...

Problems solved by technology

[0009] It can be seen that the switching technology used in the current communication system, because the active / standby arbitration and switching notification are directly performed by the underlying hardware, the upper layer application modules and service modules are in a passive state, which is not conducive to high-level equipment maintenance; and because the switching is directly performed by the Circuit switching is implemented, so it is not transparent to the upper layer application, and the switching has a great impact on the system; again, the switching process is completed mechanically by the circuit, which is inflexible and cannot support automatic manual switching; in general, when the equipment is switched It also requires data transfer, reconfiguration of backup equipment, etc., and requires a long delay, which makes it far from meeting the requirements of real-time business and high service quality in the telecommunications network

[0010] In practical application, the above scheme has the following problems: Since the device switching is initiated and executed by the underlying hardware, the upper-layer application is in a passive processing state, which does not support the maintenance of high-level devices; Configuration takes a lot of time, so the switching operation has a long delay and cannot meet real-time requirements; because the switching is realized through physical address conversion or circuit switching, it does not have transparency and flexibility, so it has a great impact on the entire communication system
