指挥控制流程的变迁往往导致网络上部署的服务不能持续满足用户的服务质量(QoS)需求,服务部署的优化调整问题亟待解决。介绍了服务组合代理的整体结构,描述了服务部署优化组件与各部件的组织交互关系,形式化定义了服务部署优化问题(SDOP),提出了部署优化算法(SDOA)并给出了算法的时间复杂度。仿真试验表明,该算法在满足用户QoS 需求和降低系统开销上具有性能优势。

The dynamic change of a command and control process may cause that services of initial deployment cannot meet user requirements for quality of service (QoS)on a continual basis. Therefore,it becomes an urgent problem to optimize service deployment.The architecture of ser-vice composition proxy is presented,and the interactive relationships between the optimization components of service deployment and each component are described.The service deployment op-timization problem (SDOP)is formally defined.A heuristic service deployment optimization algo-rithm (SDOA)is proposed and its time complexity is analyzed.Simulation results show that the SDOA can reduce deployment cost and meet users QoS need.
