摘 要:
考虑到现有光突发交换(OBS)网络协议在时延、丢包率性能上的不足,在恰量时间(JET)协议的基础上,提出了一种基于并行调度(PS)处理思想的新型资源预留协议——PS-JET协议,给出了该协议的实现方案及具体的信令帧格式,并通过分析与系统仿真,将其性能同带优先级的恰量时间(PJET)资源预留协议做了详细的比较。结果表明,PS-JET协议在实际的多跳网络中具有更好的时延性能和更低的丢包率,同时,具有和PJET同样良好的QoS区分特性。[著者文摘]

A novel resource reservation protocol for optical burst switching networks
Li Yanjun, Zhang Guoqing (Networking Research Lab of Institute of Computing Technology, Chinese Academy of Sciences, Beijing 100080)
Abstract:
In view of the present optical burst switching (OBS) protocols' problems of time delay and drapping probability, the paper proposes the PS-JET protocol, a novel resource reservation scheme based on the just-enough-time (JET) protocol and the parallel scheduling (PS) concept, and gives its signaling frame and implementation. The protocol's performance were compared with the priority just-enough-time (PJET) protocol by simulation experiments, and the results show that PS-JET not only outperforms PJET in terms of end-to-end delay and dropping probability but also can provide a basic QoS guarantee like PJET.[著者文摘]
