【摘要】 多协议标签交换(MPLS)向通用多协议标签交换(GMPLS)的迁移,实际就是,MPLSTE控制层面向GMPLS控制层面发展的过程。在迁移过程中,MPLS和GMPLS设备或网络同时存在,将出现多种互联情况。标准的互联功能要求,在使用GMPLS技术的同时,保持现有的IP/MPLS网络不受影响。更多还原

【Abstract】 The migration from Multiprotocol Label Switching (MPLS) to Generalized MPLS (GMPLS) is the process of evolving an MPLS traffic engineered (TE) control plane to a GMPLS control plane. In the course of migration, several interworking cases may exist where MPLS and GMPLS devices or networks must coexist. During the migration process, standard interworking functions are needed to allow graceful deployment of GMPLS technologies while keeping existing IP/MPLS networks unaffected.更多还原
