摘　　要：随着高速公路网的建设、交通量的增加以及新业务的扩展,传统的二层C/S结构面对日益增加的事务处理显得无能为力。针对此背景,设计了基于多层C/S结构的高速公路联网电子不停车收费系统。分析了系统的结构与功能,在此基础上设计了系统的网络拓扑结构。介绍了系统开发中一些关键性技术及实现。Because two tier C/S mode of traditional can not satisfy the request to increasing portfolio with the development of construction of freeway network, increasing of traffic, and expansion of portfolio. To this background, freeway interconnected electronic toll collection（IETC） system based on multi-tier C/S mode is designed. Architecture and function of IETC system is analyzed in detail, and based on this, network topology structure of IETC system is designed. At the same time, several critical technology and realization are introduced in the IETC system development.
