摘　　要：讨论在ＶｏＤ系统中Ｉｎｔｅｒｎｅｔ代理服务器方案与设计，提出在ＶｏＤ中采用的Ｉｎｔｅｒｎｅｔ网络层代理服务方式，网络层代理具有支持Ｉｎｔｅｒｎｅｔ未知与将来出现服务的优点，并且对用户透明，安全性高．给出了ＩＰ变换源端口代理的原理，采用了环形列表法来实现正、反代理变换，并探讨了代理服务器实现流量统计与包过滤防火墙的功能．已设计出多种代理服务．The scheme and design of Internet proxy server in the VoD system are represented in the paper. The method of proxy at network layer is proposed. Proxy at network layer has a lot of advantages. it supports unknown and new service. and it is transparent to user. and its security is high. The principle of change-IP - source- port-proxy is given. The loop-list method is used at front proxy and inverse proxy. The paper also discussed the function of IP volume statistics and firewall of package filter. Some proxy servers have been designed by using the method of this paper and they work well in practice.
