应用于全球通信网格系统的分层通信结构研究

Study on Layered Communication Architecture Used in Global Communications Grid (GCG)

全球通信网格系统的核心技术是分层通信结构。探讨了全球通信网格系统的分层通信结构,提出了基于全球通信网格系统的7层参考模型,包括任务层、应用层、服务层、传输层、网络层、数据链路层、物理层,介绍了通信系统结构对应于上述7层参考模型中的传输层和网络层,分析了全球通信网格系统层架构中分层通信协议的功能和应用。

The core technology of GCG is layered communication architecture.This paper probes into the layered communication architecture of GCG,puts forward a 7-layer reference model based on GCG,including task layer,application layer,service layer,transmission layer,network layer,data link layer and physical layer,introduces that the communication architecture corresponds to the transmission layer and network layer of abovementioned 7-layer reference model,and analyzes the functions and applications of layered communication protocol in GCG＇s layer architecture.
