摘　　要：单层用户交换平台体系结构(Single-layer User-data switching Platform Architecture,SUPA)是基于面向以太网的物理帧时槽交换(Ethernet-oriented Physical Frame Timeslot Switching,EPFTS)技术的一种未来Internet体系结构。研究了SUPA用户平台的OAM(Operation and Management or Operation,Administration and Maintenance)机制,以支持SUPANET域内的连通性诊断、故障诊断和故障恢复等功能。基于SUPA虚线路交换(Virtual Line Switc-hing,VLS)服务,重点研究了基于OAM的保护交换机制。最后,基于QVL(QoS Virtual Line)和SVL(Shared VirtualLine)服务,仿真比较了SUPA用户平台中基于OAM的故障恢复的保护效果,验证了基于QVL的保护交换比基于SVL的保护交换具有更好的QoS保障能力。Single-layer User-data switching Platform Architecture（SUPA） which is based on Ethernet-oriented Physical Frame Timeslot Switching（EPFTS） is promoted as a Future Internet architecture.SUPA User-platform OAM mechanism was introduced to provide operations including connectivity diagnosis,trace diagnosis and fault recovery in SUPA networks（SUPANET） domain.Based on SUPA Virtual Line Switching（VLS） services,the authors focused on research on SUPA OAM-based protection switching mechanisms.Finally,based on QVL（QoS Virtual Line） and SVL（Shared Virtual Line） services,OAM-based protection switching mechanisms for the User platform in SUPA networks were proved validity in simulation experiments,and the comparison of the simulation results shows that QVL-based protection switching is better than SVL-based protection switching in QoS provisioning capability.
