摘要
贵州铁路东一环,为2005年投入使用的2.5GMSTP环路,因历史原因,未能充分利用,随着维保期的结束,部分机盘未能及时修复,导致整体环路可靠性降低。目前铁路业务仍以2M为主,另加载部分小颗粒以太网业务。东一环为2.5G多业务平台设备1660SM组成,目前容量富裕度很大,完全可以承担近期内的业务扩展需求。为了能正常加载铁路业务,发挥其应用的功能,有必要对此环进行一次整治改造。并探讨尝试建立作为下一代传送网发展方向之一的OTN传输系统。
Guizhou railway east ring,for the 2005 put into use 2.5g MSTP loop,because of historical reasons,failed to make full use of,with the end,some dimension,timely repair machine dish cause the overall loop reliability reduced.Current railway business still with 2M primarily,another load part small particles Ethernet business.East a ring for 2.5g more business platform 1660SM composition,current capacity equipment is very big,can completely rich degrees in the near future business expansion of bear needs.In order to normal loading of railway operation,exert its application functionality,it is necessary to ring a regulation reform.And to explore attempts to establish as the next generation of transmission network development direction of otns transmission system.
