摘要: 通过多协议波长交换MtS(Multi-Protocol Lainbda Switching)技术向副载波域的延伸,该文提出了一种全新的宽带光网络技术方案以期实现电视网与Internet网的高效融合基于副载波标签和交换接口的多协议副载波/波长标签交换网络。利用新型复合标签,在独特的副载波/波长双层交换结构的基础上,实现了多层互动的流量工程和灵活的服务质量QoS(Quality of Service)保证,有效利用了波长资源。同时给出了双层标签交换机的框架结构,分析了其性能,并指出了该方案面临的关键问题及相关解决途径。Abstract: By extending MPAS technology to subcarrier domain, a novel broadband op-tical network scheme to fuse TV networks and optical internet with high efficiency-multi-protocol subcarrier/lambda label switching networks based on subcarrier label and switching interfaces, is proposed. By utilizing new compound label and basing on two-layer subcar-rier/lambda switching frame, a multi-layer dynamic Traffic Engineering(TE) and a flexible QoS guarantee are realized, which use wavelengths in a economical way. The structure of two-layer label switching router and its performance are analyzed and some key problems facing by this scheme and related solutions are presented.
