摘　　要：从网络平滑演进的角度看,基于分组传送同时兼容现有TDM传送技术的"全业务交换传送"的体系架构是实现光传送网向分组化方向演进的必然选择,也是电信运营商关心的主要问题之一。文章主要讨论了基于分组传送的全业务交换传送的体系结构及其实现方案,该体系结构的关键是在电层引入基于分组的T-MPLS交换技术,解决光传送网对分组业务的承载问题。该体系架构能够满足各种网络业务的传送需求,融合了数据、电路和光层传送功能于一体,支持数据/TDM/波长等不同技术信号的交换。From the perspective of smooth evolution of the network, it is the inevitable choice that the ＂Full Service Switch Transport＂ architecture which is based on packet transport to compatible with TDM transmis- sion technology to realize the evolution from the optical transport network to the packet network, and it is one of the main problems that telecom operators is concerned. This paper discussed chiefly that ＂Full Service Switch Transport＂ architecture that is based on packet transport and its implementation. And the key to this architecture is the introduction of packet-based T-MPLS switching technology in conducting layer to solve the bearing problem of the optical transport network to packet business.The architecture can meet transmission needs of various network business, integrated data, circuits and optical transmission functions, supporting the different signals switching ,such as data/TDM/wavelength.
