Abstract :
Firstly, the importance of reliability of the network control center (NCC) and difficulties in implementing the reliability are introduced. Lastly, a method to implement the reliability of NCC is presented. The crux of the method has four points: to transfer central control to distributed control by making use of backup; to realize the consistency of static data through atomic transaction and two-phase commitment (2PC); to ensure synchronisation between the main and backup processor/NCC by extracting dynamic calling data from users and control commands from the main processor/NCC; to design and realize a reliable protocol among all processors in the NCC
