铁路行包营运管理信息系统计算机网络结构的研究

Study of the Computer Network Structure on Railway Baggage and Parcel Transportation Management Information System

从网络信息源点分布、信息量及传输速率要求、网络传输通道等方面对铁路行包管理信息系统的网络设计进行了深入分析和设计 .讨论了行包运输业务对网络传输延迟及入网车站数量规模的影响 ,确定了构成计算机网络的信息源点规模、接入方式和网络基本结构 ;

This paper analyzes and designs the network architecture of China Railway Baggage and Parcel Transportation MIS from the angles of distribution of network information sources, demand of information amount and transmission speed, communication and so on. Based on the analysis over the data diagram of railway baggage and parcel information, the network transmission delay and number of network node, the node scale and its inter network mode are given. The structure of the network system is also presented. The IP address assignment method is described after network routing mods has been decided.
