Disaster-tolerant system for processing telephone traffic data

Abstract

The invention relates to a disaster-tolerant system for processing telephone traffic data, which consists of a main operation system and a standby system. A synchronous private line is arranged between the main operation system and the standby system. The standby system and the main operation system have the same internal software and hardware structure and external network connection. The main operation system is an actual operation system, and the standby system synchronously operates with the main operation system. When normally processing data, the main operation system generates synchronizing information and transforms the synchronizing information to the standby system. The standby system receives the synchronizing information and implements the treatment process, but does not transmit the result. After the main operation system has system failure or disaster, the standby system temporarily takes over production, and after the acquired data is processed, the file is transmitted into the external network. The invention realizes disaster tolerance by adopting the mode that the systems are embedded into the processing flow and the transmitted data is greatly reduced. Moreover, the mode adopted by the invention has far lower requirement on bandwidth than the disaster-tolerant mode based on intelligent storage bottom copy. The standby system and the main operation system can complete switching over in a short time.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to data communication technology, in particular to a disaster recovery system for traffic data processing. Background technique: [0002] Disaster recovery refers to the ability of data processing systems to recover after a severe disaster occurs. In the prior art, the disaster recovery technology is based on the synchronization of shared disk hardware or logical disks (such as logical devices or file systems). This method is to send all the underlying "write" operations performed on the shared disk of the primary system to the backup system through the network for follow-up execution, so as to achieve data consistency between the primary and backup systems. The feature of this method is that it is basically transparent to the application program, and disaster recovery can be realized without major modification of the application software. However, the requirements for network bandwidth ar...
