【摘要】 描述怎样运用信令协议RSVP-TE实现自动交换光网络中动态地建立、删除连接的要求。仿真实现了前向资源预留(FRP)和后向资源预留(BRP)两种不同的信令方案,并收集了阻塞率(BR)、控制信道带宽(CCB: control channel bandwidth)及连接建立时间(CST: connection setup time)等相关统计量,比较了这两种方案的性能,发现在相同的仿真环境以及相同网络负载的情况下,后向资源预留的阻塞率性能优于前向资源预留,同时后向资源预留的连接建立时间以及使用的控制信道带宽都大于前向资源预留。更多还原

【Abstract】 In this paper, we study how to setup and tear down a connection dynamically using RSVP-TE. Simulations are carried out to compare two different signaling schemes, FRP (Forward Reservation Protocol ) and BRP(Backward Reservation Protocol). Based on the simulation, some data are collected, such as block rate, control channel bandwidth, connection setup time, and so on.:We found that BRP excel FRP in BR performance, but it will cost more time and more control channel bandwidth to set up a connection in BRP.更多还原
