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

摘要

摘要: 向用戶提供多媒體業(yè)務(wù)是下一代網(wǎng)絡(luò)業(yè)務(wù)最基本、最重要的要求，QoS組播路由技術(shù)是網(wǎng)絡(luò)多媒體信息傳輸?shù)暮诵募夹g(shù)之一。該文給出了支持QoS組播的網(wǎng)絡(luò)模型，對(duì)已有的QoS組播路由算法進(jìn)行了優(yōu)化，提出了適用于下一代網(wǎng)絡(luò)的基于遺傳算法的QoS組播路由算法。仿真實(shí)驗(yàn)表明，這種算法收斂速度快，可靠性高，能夠很好地滿足下一代網(wǎng)絡(luò)QoS組播的需求。

Abstract: 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.
