时间部门 Multiplexing (TDM ) 运输网络正在演变到面向包,并且许多搬运人类的包运输技术出现了。有交通工程(PBB-TE ) 的供应商脊梁桥牌是提供好可伸缩性和可管理性的一种面向连接的包运输技术,并且保证服务(QoS ) 的质量。(GMPLS ) 概括多协议标签切换是与不同切换的颗粒度支持多重数据飞机的一种成熟运输网络控制飞机技术。控制 GMPLS 的 PBB-TE 是包运输网络(PTN ) 的一个有希望的解决方案。
Time Division Multiplexing (TDM) transport networks are evolving to packet-oriented, and a variety of carrier-class packet transport technologies have emerged. Provider Backbone Bridge with Traffic Engineering (PBB-TE) is a connection-oriented packet transport technology that provides good scalability and manageability, and guarantees Quality of Service (eoS). Generalized Multi-Protocol Label Switching (GMPLS)is a mature transport network control plane technology that supports multiple data planes with different switching granularity. GMPLS-controlled PBB-TE is a promising solution for Packet Transport Networks (PTN).
