基于以太网的高速公路通信系统应用分析

高速公路传统的通信系统一般采用基于电路交换机制的SDH系列传输网络和程控交换机实现,但高速公路的传输内容除了电话业务外都是基于包交换的业务,将高速公路的电话业务通过软交换实现,则高速公路所有的业务传输全部是包交换业务,高速公路传输系统采用基于以太网的包交换系统可以简化传输系统结构、提高传输效率,也顺应了技术发展的方向。

Application of Expressway Communication System Based on Ethernet

The traditional expressway communication system generally uses SDH transmission network based on circuit exchange mechanism and program controlled switch. But the expressway information transmission is a business based on packet switching business except the telephone business. If the telephone business is realized by soft exchange, all the superhighway information transmission would be packet switching business. The Ethernet based on packet switching system can simplify the structure of the superhighway transmission system and improve the efficiency, which conforms to the direction of the technical development.
