摘要
随着 Internet上支持的多种服务类别对 Qo S需求的增长 ,高效的 Qo S支持显得越来越重要 .路由机制是实现 Qo S保证的关键之一 ,应将路由选择与 Qo S相关联 .文中给出了 Qo S路由选择问题的描述 ,提出了在单点投递 (unicast)和多点投递 (multicast)情况下 ,利用遗传算法 (genetic algorithm)解决受多个 Qo S约束的路由选择策略 ,并对这两种情况进行了仿真 ,结果表明该策略是可行的和有效的 .
As the demands for quality of service (QoS) by multi-service in Internet are rapidly increasing, effective and efficient QoS support has becoming more and more important. The routing technology is one of the key roles to guarantee QoS, so the routing mechanism and QoS must be combined together. In this paper, the algorithm of QoS-based routing with multi-constraint using genetic algorithm for unicast and multicast is discussed. The simulation results suggest that the scheme is feasible and effective.
