CERNET卫星信道动态备份系统协议和算法的分析与设计
摘要
中国教育和科研计算机网CERNET是由国家教育部领导和主
持建设，连接我国教育系统和科研单位的全国性计算机互连网络。
CERNET近期正在进行主干网的升级，升级后主干网将为622Mbps
～2.5Gbps的SDH，原有的卫星信道转为备份系统。
本项目采用动态备份方式，开发CERNET主干网卫星信道动态
备份系统的相关程序代码，提高主干网的可靠性和卫星系统的利用
率，优化主干网卫星通信系统转发器的效率。
本论文详细阐述了该项目中的协议和算法的分析与设计，这是
本项目编程实现的基本依据。
CERNET(Chinese Research and Education Computer Network) is
sponsored by Ministry of Education which is a nationwide network
covers most of the research and education units in China. The backbone
of CERNET is upgrading recently. The backbone of it will be promoted
to SDI-1 from 622Mbps to 2.5Gbps while the former satellite channels
will turn to be backup system.
This project will implement the backup system of the backbone of
CERNET by dynamic distribution. It will improve the reliability of the
backbone network and also optimize the efficiency of satellite system.
In this article, we will discuss the analysis and design of the
protocol and arithmetic in Dynamic Backup System of CERNET
Satellite Channel. It is the basic rules that to accomplish this project.
