A Novel Protocol for Effect Transmission of The Real Time Traffic in Optical Burst Switching Networks
一种新颖的光突发交换网络中高效传输实时业务的协议

A protocol called VTDM_RT is proposed for OBS networks to support low rate real time traffic.No fixed-position time slot is defined for the channel.The real time service request will search for free positions of the channel and occupy the channel periodically,the core switch has no buffer,and will forward the real time traffic periodically.Approximate theoretical analysis and simulation show that the protocol can decrease the blocking probability and data loss rate.The lower the data rate is the lower the blocking probability and the higher the wavelength utilization.
