摘    要:研究了IP/DWDM光因特网中的集成式QoS组播路由算法,在考虑负载均衡的前提下,针对用户组播请求与柔性QoS需求,寻找一棵QoS组播路由树。由于该问题的NP难属性,因此基于禁忌搜索算法来构造费用近优QoS组播路由树,同时集成一种基于分段和波长图思想的波长分配算法,一体化解决路由与波长分配问题。仿真结果表明,提出的算法是可行和有效的。

关 键 词:IP/DWDM光因特网  柔性QoS  组播  禁忌搜索  负载均衡

Abstract:An integrated QoS multicast routing algorithm in IP/DWDM optical Internet is proposed. Considering load balancing, given a multicast request and flexible QoS requirement, to find a QoS multicast routing tree is NP-hard. Thus, a tabu search based algorithm is introduced to construct a cost suboptimal QoS multicast routing tree, embedding the wavelength assignment procedure based on segment and wavelength graph ideas. Hence, the multicast routing and wavelength assignment is solved integratedly. Simulation results show that the proposed algorithm is both feasible and effective.
Keywords:IP/DWDM optical Internet  Flexible QoS  Multicast  Tabu search  Load balancing
