| 摘 要： | 光突发交换(OBS)相对传统的电路交换方式具有更高的传输效率和更短的网络时延,而相对于未来网络的发展趋势光分组交换,光突发交换具备更现实的可行性.在OBS中,突发汇聚是一个很关键的技术,它对OBS网络的性能有着重要的影响,在本文中,我们对突发汇聚机制进行了较深入的研究,并提出了一种新的突发汇聚算法,它对抑制网络流量的自相似性,提高突发传输效率和避免在不同节点由于突发同步所引起的带宽资源竞争都有较好的结果.

| Abstract: | As a promising switching paradigm,Optical Burst Switch(OBS) was proposed for optical networks showing higher efficiency and shorter delay than traditional circuit switching,and it is more feasible than optical packet switching.In OBS,burst assembly is one of the critical technologies,and will significantly affect the performance of networks.In this paper,we focus on the study of burst assembly mechanism,and propose a new burst assembly algorithm,which reduces the self-similarity of IP traffic,enhances the data burst utilization and avoids the bandwidth contention due to sending burst data synchronously at different ingress nodes. |

| Keywords: | optical burst switching assembly threshold self-similarity ON /OFF sources |
