电力SDH/MSTP传输网主站侧设备以太网资源优化

Ethernet Resource Optimization of Main Station Side Equipment in Power SDH/MSTP Transmission Network

随着现代电网对数据通信业务需求的不断增加,地市供电公司SDH/MSTP传输网承载以太网汇聚业务的种类和数量增长迅猛。业务资源需要在主站侧传输设备汇聚落地,占用大量以太网虚拟端口(VCTRUNK)资源。由于SDH传输设备槽位和以太网板资源有限,造成主站侧传输设备资源紧张。针对此问题,从业务的数据类型和带宽需求出发,充分结合当前电力企业SDH传输网和综合数据网资源,采用以太网业务二次汇聚、转移业务至综合数据网以及SDH与综合数据网联合承载等方法,优化SDH/MSTP主站侧设备以太网业务承载方式。最后,通过实例验证所提方案能够显著减轻SDH/MSTP主站侧设备承载以太网业务的压力。

With the increasing demand of modern power grid for data communication services,the kinds and quantity of Ethernet convergence services carried by SDH/MSTP transmission network of power supply companies in cities and regions are growing rapidly. Business resources need to be converged and landed in the transmission equipment at the main station side,which takes up a lot of Ethernet virtual port(vctrunk) resources. Due to the limited resources of SDH transmission equipment slot and Ethernet board,the main station side transmission equipment resources are limited. In view of this problem,starting from the data type and bandwidth requirements of services,fully combining the current SDH transmission network and integrated data network resources of power enterprises,adopting the methods of secondary convergence of Ethernet services,transfer of services to integrated data network and joint bearing of SDH and integrated data network to optimize the Ethernet Service bearing mode of SDH/MSTP main station side equipment. Finally,an example is given to verify that the proposed scheme can significantly reduce the pressure of the SDH/MSTP master equipment to carry Ethernet services.
