Self-Organization Method for Survivability Enhancement of Information System Service

As a new direction in network security,the survivability of information systems is different from traditional network security.This paper presents a service self-organization method based on connection handoff. According to service processing flow,the system is divided into communication,service distribution,and service supply modules.Backup modules survivability information is send to online modules and gets the list of newest service states.When the survivability of a module is highest,the self-organization strategies are implemented using multi-handoff technology.The system possesses the merits such as transparency to users,flexibility and operability of the configuration.Experiments confirm that this method can enhance the quality of service and improve service survivability.
