摘　　要：SOCKS 5是一个标准的网络代理协议。其原理是SOCKS 5代理服务器和客户建立联系后,客户的数据包都以TCP数据包的形式发送到SOCKS 5代理服务器,然后由其转发,并将接收的数据分发给相应的客户。基于TCP代理过程为:双方建立连接,客户代理请求协商,客户身份及口令验证,TCP协商并实现连接、绑定、UDP请求等操作。基于UDP代理协议过程前3项同TCP,其后为UDP协商和数据收发。使用SOCKS 5代理技术,在网络寻呼系统应用软件中,采用SOCKS系列和WINGATE系列代理服务器,成功实现了TCP和UDP代理。SOCKS 5 is a standard Internet proxy protocol. After connection was established between SOCKS 5proxy sever and client, data packages of clients at TCP data packages pattern is sent to SOCKS 5proxy sever, then the sever relay data received to correlative clients. TCP proxy process includes establishing connection between proxy sever and clients, client proxy requested negotiating, authenticating username/password, TCP negotiating and establishing connection, binding and UDP requesting, sending or receiving data packages. The previous three steps of UDP-based proxy protocol process are the same as that of TCP-based proxy, the post steps is UDP negotiation and sending or receiving of data. During development of net-call application software, the TCP and UDP proxy was successfully implemented with SOCKS and WINGATE series proxy server and Socks 5 proxy technology.
