摘　　要：基于OCDM(光码分复用)技术和MPLS(多协议标签交换)技术,采用分离编解码方案对可并行光码标签路由技术进行研究。利用光极性特性实现标签与净荷的分离,采用FBG(光纤布拉格光栅)编码器对数据进行编解码。由于系统采用码分复用,允许不同净荷在时间上重叠,同一波长的OCDM标签路径在核心路由器中并行处理,提高了系统的吞吐量。On the basis of the OCDM and MPLS technologies,the parallel optical code-label routing technology is studied by using the separated coding/encoding scheme.The label and payload are separated by using the optical polarity characteristics and the data are coded and encoded using the FBG encoder.As the OCDM technology is adopted for the system,different payloads are permitted to be overlapped in time and the OCDM label paths on the same wavelength can be processed in parallel in the core router,thus increasing the system throughout.

关 键 词：光码分复用 光标签路由器 并行处理 吞吐量
