光传送网的一体化网管研究

Integrated Management of Optical Transport Networks

光传送网技术可望成为下一代的主导传送网技术。详细讨论了光传送网（ＯＴＮ）和光传送网的管理技术。结合ＴＭＮ、ＳＮＭＰ和ＣＯＲＢＡ，着重研究了ＯＴＮ的一体化网管。一种Ｑ－Ａｄａｐｔｅｒ被提出来用于集成ＴＭＮ和ＳＮＭＰ，一种直接的ＣＯＲＢＡ／ＳＮＭＰ接口被用来实现ＣＯＲＢＡ和ＳＮＭＰ的集成。最后简要分析了几个和ＯＴＮ一体化网管相关的问题：ＩＰ层和光层的联合路由，多层保护以及ＯＴＮ的ＯＡＭ技术。

Optical transport networks(OTN) technology is expected to play a vital role in the next-generation transport networks. In this paper, the technology of OTN and management of OTN is discussed. Combined with TMN, SNMP and CORBA, integrated management of OTN is investigated. Q-adapter is proposed to integrate TMN and SNMP together, and a direct CORBA/SNMP interface is given to implement the integration of CORBA and SNMP. Finally, several issues concerning integrated management of OTN are also discussed, such as integrated routing in LP layer and in optical layer, multilayer protection of OTN and OAM technology of OTN.
