摘要 将IP路由器和光交叉连接器集成在一起构成一种新的节点结构 ,由这种节点所组成的网络成为一种很有吸引力的下一代光互联网结构。IP波长路由技术就是基于这种网络结构而提出的 ,它包含了GMPLS(广义多协议标记交换 )交换和转发序列中的两种粒度 :分组和波长。研究了IP波长路由器的设计问题。首先分析了有关文献中给出的一种节点结构所存在的问题和局限 ,然后提出一种新型节点结构以解决这些问题。另外 ,将IP交换的两个协议IFMP(Ipsilon数据流管理协议 )和GSMP(通用交换机管理协议 )进行适当扩展 ,用来支持IP波长路由网络。最后对IP波长路由器的主要模块———流分类器的选择以及IP波长路由器性能参量的确定进行了讨论。 The network architecture with each node integrating an IP router and an OXC is an attractive paradigm for the next generation optical Internet.IP wavelength routing,which includes two types of switching and forwarding hierarchies(packet and lambda)in the GMPLS field,is based on this kind of architecture.This paper addresses the design issues of an IP wavelength router.Based on analyzing the problems and shortcomings of the previous general node structure,a novel node structure is proposed,which overcomes the problems encountered by the previous scheme.Two IP switching protocols,IFMP and GSMP,are extended to support IP wavelength routing networks.The flow classifiers,which are main components of these node structures,and the performance metrics of these structures,are also discussed.
