A Survivability Information System Based on Service Self-Organization

A survivability information system based on service self-organization is proposed under the precondition of modules redundancy backup. The service self-organization way divides the system into services communications modules, services distribution modules, data storage modules according to service processing flow, the backup modules send its survivability information to the working modules duly, and get the latest service states list. When a module has the highest survivability, the system will do the service self-organization through different connection handoff techniques according to the functions of the modules and their location in system architecture. The validity of the survivability calculation method is proved by the simulation experiment. Examination proved that the method proposed in this paper can enhance the service survivability both of the steady state and instantaneous state by setting up a Web server in the network environment.
