Research And Design Of Automatic Generation System For OTN Service Routing

With the rapid development of Internet communication,information capacity and transmission frequency is higher,so the requirement for the transmission bandwidth,delay and stability is also higher.New applications drive the development of the communication technology,and now OTN has become the mainstream transmission technology.At present,China OTN network is a three level network,an OTN service may involve two local network,two provinces of 2nd trunk network and 1st trunk network,the maintenance problems involve many operators,long routing distance and different transmission equipments.The traditional OTN service is mainly opened by humans,with the shortcomings of long service opening time,not optimal business router,large business delay and lower network efficiency.This research focus on the research and design of OTN service routing automatic generation system,to explore a method of business route automatic generation,less service delay and high network resource utilization,to accelerate the service open of OTN and enhance the user perception.This research proposes the schemes of OTN capacities restore,inter-network plan,OTN service router searching and evaluation,and system total solution.At the same time,OTN service routing automatic generation is not only applied to the OTN business open,but also can be applied to temporary scheduling,business plan,business restructuring and other application scenarios,will help enhance the overall management level of OTN network.
