Abstract:

Fast and stable switch-over is one of the key elements of any high performance disaster recovery system.But it is not an easy task because of the complexity and unpredictability during the switch-over process,especially when there are several systems which may exchange data between them.Petri net has been widely used in system control based on real-time status in many industries,but not in China's telecommunication industry.In order to improve the disaster recovery performance of China Telecom's billing systems,for the first time,a middleware based on Petri net is introduced and the best RTO in China's Telecommunication industry is achieved.

Key words: Petri net, billing, disaster recovery, middleware
