光突发交换网络中冲突解决方法研究

The Research on Contention Resolution of Optical Burst Switching Networks

光突发交换(OBS)网络被认为是下一代光因特网的典型代表,其中,光突发数据包在节点的竞争问题是OBS网络中需要解决的关键问题之一。该文重点研究了突发数据包之间因争夺链路资源而导致冲突的四种竞争解决方案:波长转换、光缓存、偏射路由和突发包分割,并分析了它们的优缺点。在此基础上,提出了OBS网络中冲突解决方法的发展趋势——联合解决机制。

Optical burst switching（OBS） network is considered to be the typical representative of next-generation optical Internet,and contention resolution is the key technology in optical burst switching networks.Four kinds of contention resolution mechanism are researched in detail in this paper,which include Wavelength Conversion,Optical Buffer,Deflection Routing and Burst Segmentation.And their advantages and disadvantages are analysed.On this basis,the combined schemes which combine a variety of contention resolution mechanism are also proposed in this paper at last.
