光传送网(OTN)在县乡层面的应用探讨

Discussion on the application of OTN in the county

根据目前通信行业三大运营商的业务发展需求,OTN技术的组网和建设已经从骨干网、城域网向本地网以及更下一层延伸。在本地网的县与乡镇层面,从科学组网、合理选型、智能调度和资源整合等方面阐述如何科学地部署OTN网络。对县乡OTN各种试用场景和设备选型进行了对比分析,将对光传送网络的汇聚层建设有指导意义。

According to the business development needs of the three major operators in the communication industry, the net- work and the construction of OTN technology has been extended from the backbone network, metropolitan area network, to the local network and the next layer. In the county and township levels of local network, how to deploy the network, inclu- ding： science, reasonable selection of networking, intelligent scheduling, resource integration and so on, is worthy of our thinking and demonstration. All resuhs of the analysis of various test schemes and the selection of equipment, can guide the construction of future optical transport networks.
