摘要 ROADM提供了光网络的灵活性和重配置能力,GMPLS是多层次交换网络统一的控制平面。在介绍ROADM技术和GMPLS协议的基础上,描述了由GMPLS控制ROADM构成的光网络结构,并完成扩展GMPLS路由协议以支持在ROADM端口约束条件下的路由。 ROADM makes optical networks flexible and reeonfigurable, while GMPLS provide a unified control plane for muhilayer switch. In this paper, HOADM and GMPLS are introduced, then the framework of OTN based on GMPLS-controlled ROADM is presented, and routing protocol in GMPLS is extended to support the constraint of ports in ROADM.
