引言随着我国高速公路建设突飞猛进的发展．各省高速公路联网收费、集中监控等工作正在实施之中,伴随而来的突发性图像业务对通信承载系统提出了更高的要求．对于通信网络高生存性、可扩展性、易管理性等方面的需求日益突出．基于传统的SDH技术以及后来的MSTP技术搭建通信网络．在这种趋势下已经越来越“力不从心“．自动交换光网络(Automatic Switched Optical Netwotk,以下简称ASON)的出现很好地解决了现有通信网络的问题。以目前的发展进度和成效来看．ASON将成为未来光通信以及高速公路通信专网发展的方向。
Introduction With the rapid development of China’s highway construction. Provincial highway toll collection, centralized monitoring and other work is being carried out, accompanied by the sudden image of the communication bearer system put forward higher requirements. There is an increasing demand for high survivability, scalability, and manageability in communications networks. Based on the traditional SDH technology and later MSTP technology to build communication networks. In this trend has been more and more “powerless.” The emergence of Automatic Switched Optical Netwotk (ASON) solves the problem of existing communication networks well. In the current progress and effectiveness of development point of view. ASON will be the future of optical communications and highway communications private network development.
