研究了一种有限范围多波长转换器(LMWC)反馈共享连接和全单波长转换器(FRWC)输出共享连接相结合的解决全光组播波长资源竞争的解决方案,并提出有限范围多波长转换器优先的波长变换调度算法,以最大双向匹配最小边长权重方法选择多波长转换器解决冲突光组播波长变换。仿真结果表明:所提的结构与输出共享全多波长转换器(FMWC)节点结构或输出共享FRWC节点结构相比,都能够明显降低光组播节点的分组丢包率(PLP),减少系统需求LM-WC多波长转换器的数目,提高多波长转换器的利用率;LMWC具有不同波长转换范围对光分组冲突解决性能也有影响。
A solution to the competition of all-optical multicast wavelength resources based on the LMWC feedback shared connection and the full single-wavelength converter (FRWC) output shared connection is studied. A limited range of multi-wavelength conversion Priority wavelength conversion scheduling algorithm, the maximum bidirectional matching minimum edge length weight method to select multi-wavelength converter to resolve the conflict optical multicast wavelength conversion. The simulation results show that the proposed structure can significantly reduce the packet loss rate (PLP) of optical multicast nodes and reduce the system requirements compared with the output shared full-wavelength converter (FMWC) node structure or the output shared FRWC node structure LM-WC multi-wavelength converter to improve the utilization of multi-wavelength converter; LMWC with different wavelength conversion range of optical packet collision resolution performance also has an impact.
