基于光码的多协议标记交换(OC-GMPLS),利用光码分复用(OCDM)技术,将基于波长的标记交换(MPλS)粒度进行了细分,扩大了标记空间;而二维光码增加了一个自由度,扩大了码容量。提出了标记扩展性分析模型,分析了MPλS和OC-GMPLS的标记空间扩展性,并对OC-GMPLS中两种二维光码的标记空间扩展性进行了对比分析。仿真结果表明,OC-GMPLS大大扩展了标记空间,合理选择编码方式可以扩大标记空间。
Based on optical code multi-protocol label switching (OC-GMPLS), the granularity of wavelength-based label switching (MPλS) is subdivided using optical code division multiplexing (OCDM) Added a degree of freedom, expanding the code capacity. The marker scalability analysis model is proposed. The label space expansibility of MPλS and OC-GMPLS is analyzed. The contrastive analysis of the label space expansibility of two kinds of two-dimensional optical codes in OC-GMPLS is also made. Simulation results show that OC-GMPLS greatly expands the mark space, and selects the coding mode reasonably to expand the mark space.
