一种光组播竞争解决方案，反馈共享有限范围多波长转换器（LMWC）与输出共享全范围单波长转换器（FRWC）相结合，本文在波长域中研究了有限距离多波长激光器，提出了波长优先算法为竞争光多播分组分配波长信道资源，提出了最大二分匹配最小边权的方法选择波长信道资源，并给出了相应的算法仿真结果还表明，与全范围多波长转换器的输出节点共享结构和全范围单波长转换器的输出节点共享结构相比，该方案显著降低了丢包率，减少所需的有限范围的多，进一步的研究还表明，不同的波长转换范围对所提出的方案有不同的影响性能
An optical multicast contention solution scheme,feedback shared limited-range multi-wavelength converters(LMWC) combined with output shared full-range single wavelength converters(FRWC),is studied in this paper in wavelength domain.The limited-range multi-wavelength first algorithm is put forward to assign wavelength channel resource for contending optical multicast packets.The method of maximum bipartite matching with minimum edges weight is brought forward to select the multi-wavelength converter to resolve the multicast confliction with wavelength conversion.Compared with the output share-per-node architecture of full-range multi-wavelength converters,or the output share-per-node architecture of full-range single-wavelength converters,our simulation results also show that the proposed scheme reduces the packet loss probability markedly,cuts down the required number of limited-range multi-wavelength converters and improves the wavelength converter utilization.The further study also indicates that different wavelength conversion ranges have different effects on the proposed scheme performance.
