【摘要】 光突发交换(OBS)是实现IP/DWDM网络的一种极有前途的方案.该文提出了两种新型的OBS网络数据信道调度算法:最少波长转换(MWCT)调度算法和区分服务(SD)调度算法。通过仿真,证明了这两种算法在减少OBS网络中的光信号的波长转换和保证高优先级数据可靠传输方面比已有的FF和LAUC调度算法具有更好的性能。更多还原

【Abstract】 Optical Burst Switching (ODS) is a promising solution for realizing IP/DWDM. In this paper, two new data channel scheduling algorithms in OBS networks, Minimum Wavelength Conversion Times (MWCT) algorithm and Service Differentiation (SD) algorithm, are proposed. Computer simulation has demonstrated that MWCT algorithm leads to much fewer wavelength conversion times and the SD algorithm can provide better transmission reliability in OBS networks for high priority data comparing with the existing FF and LAUC algorithms.更多还原
