摘要
随着业务流量的快速增长和OTN网络逐步Mesh化,如何更高效疏导网络节点流量,实现多个子框间资源灵活调度和容量按需扩展等成为亟待解决的问题。OTN集群通过集群交叉将节点内OTN设备互联形成共享资源池,实现子架槽位和单板资源共享、业务可跨子框调度,能够为提升OTN网络效能带来诸多价值。介绍了OTN集群技术的发展现状和实现方式,分析了OTN集群的现网应用场景。最后从多个维度对OTN集群与传统灰光互联OTN的优劣进行了分析,提出OTN集群现网应用部署策略。
With the rapid growth of service traffic and the gradual meshing of OTN networks,how to dredge traffic more efficiently and achieve flexible scheduling of resources and capacity expansion on demand among multiple sub-frames have becomed problems to be solved urgently.The OTN cluster realizes sharing of sub-rack slots and boards resource,and scheduling services across sub-frames by forming a shared resource pool of interconnecting OTN devices through cluster crossover,which brings many values for telecomn operators in improving OTN network performance.Firstly,it briefly introduces the development status and implementation of OTN cluster technology,and analyzes the application scenario of OTN cluster in existing network.Finally,the advantages and disadvantages between OTN cluster and traditional OTN are analyzed on multiple dimensions,and the strategies of OTN cluster application and deployment in existing network are proposed.
