摘　　要：考虑光突发交换(OBS)网络具有部分波长转换能力和多业务承载需求,结合并行调度方案,提出了基本型快速分段信令协议(SFP),并对其进行了多业务能力扩展,另外,还提出了一种面向多业务承载的OBS SFP,即增强型多业务分段快速协议(SFP-MS)。仿真结果表明,与普通后向资源预留协议(BRP)相比,基本型SFP的丢包率和端到端时延较低;而增强型SFP-MS除了能维持同步业务周期性外,还能降低节点处理突发控制包(BCP)的数量,提高同步数据突发包(DB)有效数据填充率,增强多业务承载能力。Considering optical burst switching （OBS） network with wavelength conversion and multi-service traffic load demand, this paper proposed a new segmented and fast control signaling protocol （SFP） based on the parallel scheduling idea, and enhanced the multi-service carrier capability of the SFP. In addition, the pa- per revised an OBS SFP enabling multi-service carrier, which is called SFP for multi-service（SFP-MS）. Shown by simulation results, compared to back resource reservation protocol （BRP）, SFP can reduce the delay and packet loss probability. During carrying synchronous business cyclical, SFP-MS can effectively reduce the number of processing burst control package （BCP） at nodes. Besides, SFP-MS can also increase the payload probability of data burst packet（DB）, and enhance the capacity of multi-service traffic load.
