一种基于QoS的多维资源近似最优分配算法

AN NEAR-OPTIMAL MULTIDIMENSIONAL QOS-BASED RESOURCE ALLOCATION

分布式多媒体应用需要同时使用多种系统资源来保证用户的 Qo S要求 ,如何在竞争资源的应用之间合理分配资源 ,使得在满足用户 Qo S要求的基础上资源的利用率最高成为一个急需解决的问题 .针对分布式多媒体应用的特性提出了一种基于 Qo S的多维资源近似最优分配方法 ,该方法能显著地降低资源最优分配问题中的计算复杂度 ,并获得近似最优的资源分配方案 .

Distributed multimedia application must use multi resources at the same time to guarantee the user's QoS. How resources allocated among competing applications to guarantee the user's QoS and achieve maximum resource utilization becomes an urgent problem. According to distributed multimedia applications' characteristics, a method of multi dimensional resource near optimal allocation is proposed based on application's QoS. The method can prominently reduce complexity on resource optimal allocation and reach near results.
