光突发交换网络中突发组装办案研究

光突发交换（Optcal Burst Switching.OBS）被认为是在下一代光网络中起到至关重要作用的一种交换技术。边缘节点处突发包的组装作为业务接入OBS网络的第一步，是OBS研究的关键课题之一。 该文重点阐述了几种常用的突发组装方案：基于突发长度组装方案、基于组装时间组装方案、混合组装方案及自适应组装方案，并分析了它们的性能和优缺点。最后指出综合考虑网络业务流量、边缘节点的处理速度和信道带宽等因素的更加有效的突发组装算法是重点研究的内容。

The Research on Burst Assembly Mechanism of OBS Network

Optical Burst Switching has been considered to be a kind of exchange technology that plays a vital role in the next-generation optical network.Burst assembly in OBS networks edge node is the first step of service access,so it＇s one of the key resear ch topics in OBS network.Few kinds of burst assembly mechanisms are researched in detail in this paper,which include FBL（Fixed Burst Length）,FAP（Fixed As-sembly Period）,MSMAP（Mix Burst-Size Mix Assembly Period） and Adaptive Data Burst Assembly algo-rithm.Their performance and advantages also disadvantages are analyzed.Finally this paper point out that more effective burst assembly algorithm that consider the factors of network business traffic,pro-cessing speed in edge node and channel bandwidth is the key research direction.
