摘要

光突发交换（OBS）是近年来出现的一种新型光交换技术。OBS结合了光电路交换和光分组交换的优点

比电路交换更加灵活

而与光分组交换相比又提供了光层的统计复用能力且易于实现。OBS能提供高吞吐量、高带宽利用率和低时延

使其成为下一代城域网的有力竞争者。文章采用M/G/1排队模型

在限定条件下对不同优先级的突发包在OBS环网中的传输延迟进行了分析

最后给出了突发包在OBS环网中所经历的时延。

Abstract

As a novel optical switching technology proposed in recent years

Optical Burst Switching（OBS） combines the advantages of Optical Circuit Switching（OCS） and Optical Packet Switching（OPS）

but it is more flexible than OCS and provides more easily realizable statistical multiplexing capabilities at the optical layer than OPS.In addition

OBS provides high throughput

high-bandwidth availability and low transfer delay

making it a forceful competitor for the next-generation MAN.Using the M/G/1 queuing model

we develop an analytical approximation for the transfer delays of different priority burst packages under a constrained condition and derivate the transfer delays of the burst packages in OBS ring networks.
