下一代网络中基于遗传算法的QoS组播路由算法

A QoS Multicast Routing Algorithms Based on Genetic Algorithm in Next-Generation Networks

向用户提供多媒体业务是下一代网络业务最基本、最重要的要求,QoS组播路由技术是网络多媒体信息传输的核心技术之一。该文给出了支持QoS组播的网络模型,对已有的QoS组播路由算法进行了优化,提出了适用于下一代网络的基于遗传算法的QoS组播路由算法。仿真实验表明,这种算法收敛速度快,可靠性高,能够很好地满足下一代网络QoS组播的需求。

Multimedia service is the basic service in NGN. QoS multicast routing algorithms technology is one of the key technology of multimedia transfer, The network model of QoS multicast routing based on project-the key technology of the next-generation networks is presented, Some other approaches are optimized in this paper, and an approach based on genetic algorithm is proposed. The simulation results demonstrate that the proposed algorithm （NGNMR-GA） has fast convergence speed and high reliability, it can meet the requirement of the next-generation works,
