卫星综合信息网面向任务的协作机制研究

以卫星综合信息网为研究背景,将面向任务的协作机制引入其网络管理系统,提出了基于分层管理的协作机制框架,包括协作模型、协作过程和协作通信机制的研究.论文设计了面向任务的协作分解语法和异步执行任务过程,根据不同的任务,动态生成协作产生者--响应者模型,并设计了信息同步机制以及协作通信机制的消息通信类型.该协作机制的实现可以提高卫星综合信息网的资源利用率,使卫星网网络管理更适应网络拓扑结构的变化,易于扩展.

Task-oriented Cooperation Mechanism for Satellite Information Network

Raised on the basis of satellite information network, task-oriented cooperation mechanism is drawn into the domain of space network management. Cooperation architecture is raised on the basis of hierarchical management, including cooperation models, cooperation processes, and cooperation communications mechanism. Task-oriented cooperation decomposition syntax and the process of asynchronous operations are designed; cooperation producer-responder model is dynamically generated on the basis of different tasks. Cooperation communication message types are designed; information synchronous mechanism and cooperation communication mechanism are described. The accomplishments of this cooperation mechanism could enhance the resources utilization of satellite information network; space network management could adapt itself more to the change of network topology architecture and develops itself easier.
