网络中心战中服务质量选路的研究

介绍了网络中心战的概念和网络中心战架构中分布式无主节点网络体系结构，提出了网络中心战的业务需求模型。在综合分析网络资源状况和服务质量度量参数的基础上，结合网络中心战对实时性要求较高的特性，提出了以探测器到火力控制单元的网络时延作为服务质量选路标准。以3节点旅（团）级网络中心战演示实验平台为例，提出了一种计算网络中心战架构中端到端时延和获取路径信息的算法，开发了Server／Client架构计算程序，选取探测器到火力控制单元之间的最小网络时延的链路作为最优路径。解决了网络中心战中路由选择的关键问题，满足了网络中心战对时延的要求，并且可用于多业务点提供业务时最优路由的确定。

Study on QOS Routing in Network Centric Warfare

The concept of network centric warfare (NCW) and the distributed equal-node network architecture in NCW are introduced in this paper. The data flow requirement model in NCW is presented. Based on synthetic analysis of network resource, the QOS (Quality of Service) parameters and their characters, the high requirement of real-time synchronization in NCW, the single QOS routing constraint, and the network latency between the detector and weapon control station, are presented. To take an example for 3-node brigade (regiment) level NCW demonstration platform, the algorithm of end-to-end network latency and path information in NCW are presented. The algorithm program based on Server/Client architecture is developed. The optimal path is the link whose latency between the detector and weapon control station is the smallest. This paper solves the key issue and satisfies the needs on network latency in NCW. The study results can be widely applied in the decision of the optimal path which is based on multiple service provision points.
