Research on SUPANET OAM-based Protection Switching
SUPANET基于OAM的保护交换研究

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.
