摘要
对MPλS进行扩展,提出基于GMPLS的新型二维标记交换(MPCλS:Multi-Protocol Code-λ Switching),利用光码分复用(OCDM)结合MPλS对数据进行复合多维度的标记交换,降低了所需波长数;给出网络拓扑发现和复合LSP的建立过程算法,实现资源的灵活配置;引入通用成帧规程(GFP),并对其进行扩展改进,实现对新型二维标记交换网络的流量整形。
A novel 2-D optical label switching technology based on GMPLS, named MPCλ S （ Multi-Protocol Code-λ Switching） is proposed. By MPλ S technology and OCDM, optical label switching is carded out in multiple dimension, in which less wavelengths are used; Algorithms for network topology discovery and multi-LSP tunnel establislishment are provided; GFP is extended and re-defined to perform traffic engineering.
