| As information technology develops, the scope of battlefield extends and the speed of war goes faster, because of its weakness in interaction and its poor information processing, the traditional Command and Control System can not adapts modern battlefield well.It is a trend that the traditional “Chimney Type”Command and Control System will be replaced by Information Technology, Network-based Command and Control system. In order to solve the problem in service interaction of Command and Control System, we urgently need to improve service interaction and communication of Command and Control System in various allegations of nodes.The service interaction pattern publish/subscribe has already been applied in many fields such as equipment management monitoring system.The industry has also launched the relevant research work on publish/subscribe interaction model.At present there are two kinds of specifications for publish/subscribe interaction model, respectively is WS-Notification and WS-Eventing.The paper adopts the WS-Notification specification, the publish/subscribe interaction model based on content is defined in it, also interfaces that handle notifications is definied.To integrate the publish/subscribe interation model that based on WS-Notification into the framework of webservice provides important significance for solving the problems that occurs in large complex distributed systems such as command and control system.The paper introduces the service interaction model publish /subscribe of command and control system based on SOA.At the same time, the key technologies that support publish/subscribe service interaction model of webservice are discussed in detail.Based on detail study the whole structure of command and control system based on SOA, operation model of the system and implementation mechanism, the design of publish/subscribe service interaction model is proposed.Finally the service interaction of Command and control system is realized. |
