高速公路专用主干通信网组网技术

Networking Technology of Special-Purpose Backbone Communication Network for Freeways

介绍了专用通信网拓扑结构以及光同步数字通信网(SDH)、异步传输交换技术(ATM)、动态分组光纤传输技术(DPT)、光波长分割复用技术(WDM)和IP网络技术的发展,指出动态分组光纤传输技术(DPT)是目前最有前途的组网技术。最后列举了上海公路通信网的拓扑结构和采用动态IP分组光纤传输技术的应用实例。

Based on the application example in Shanghai Highway Communication Network on the application of topological structure and DPT, described hereby is the development of topological structure & SDH, technologies of ATM, DPT, WDM and IP network, in which the DPT is considered the networking technology with a most prospective future.
