广播电视通信广域SDH传输网架构优化与建设方案研究

Research on Architecture Optimization and Construction Scheme of Wide Area SDH Transmission Network for Radio and Television Communication

随着广播电视行业运营管理类业务与基础复用类业务不断发展壮大,对于广域数据传输的稳定性和可靠性提出了更高的要求。通过对广域同步数字体系(Synchronous Digital Hierarchy,SDH)通信技术和广播电视业务需求的分析,对SDH传输网络的组织架构进行了优化,给出了广域SDH通信网的建设实施方案,并讨论了该方案中数据传输量、结构复用率以及业务匹配度等问题,为后续广播电视广域通信的网络化建设指明了方向。

With the continuous development of operation management services and basic multiplexing services in the radio and television industry,higher requirements are put forward for the stability and reliability of wide-area data transmission.Through the analysis of wide area Synchronous Digital Hierarchy(SDH)communication technology and radio and television service requirements,the organizational structure of SDH transmission network is optimized,the construction implementation plan of wide area SDH communication network is given.The problems of data transmission volume,structure multiplexing rate and business matching degree in this scheme are discussed,which points out the direction for the subsequent network construction of radio and television wide-area communication.
