摘    要:本文提出一种在多域光网络中基于优先级的路由波长分配算法.算法设计旨在解决复杂网络拓扑下,多任务请求路由波长分配问题.本文首先根据复杂网络拓扑情况与任务请求状况,完成多域的划分,对跨域任务的最短路由进行路由分裂;其次依据域内与域间优先级设定策略,完成多任务请求优先级设定;按照优先级顺序,采用模糊优化波长分配算法完成波长分配.仿真结果表明本算法在处理复杂网络拓扑、多任务路由波长分配问题上效果明显,有效的降低了网络请求阻塞率,提高了光网络资源利用率.

关 键 词:多域  多任务  优先级  路由波长分配

Abstract:We present an effective algorithm for solving multi-requests'routing and wavelength assignment in multi-domains networks based on priority algorithm (MD-PRWA).We partition the multi-domain according to the state of the complex networks and multi-requests and divide the shortest route of the inter-domain route.Secondly,we use the priority algorithm of inner-domain and inter-domain to determine the priority of the multi-requests;at last RWA (routing and wavelength assignment) in the whole network is solved in the light of the multi-requests' priority.The simulation results show that MD-PRWA algorithm performances well,reduces the network request blocking rate effectively and improves the optical network resource utilization greatly in solving the multi-requests RWA problems in complex networks.
Keywords:multi-domain  multi-requests  priority  routing and wavelength assignment (RWA)
