分布式VoD中基于用户类的代理动态带宽管理

Dynamic Bandwidth Management in Distributed VoD based on the User Class Using Agents

H S Guruprasad, H D Maheshappa

摘要:

本文提出了一种动态带宽管理算法,利用代理技术,将更多的带宽分配给级别较高的用户,并将更高的优先级分配给级别较高的视频。用于有效地分配带宽的视频的流行度和权重配置文件定期更新的移动代理。所提出的方法分配更多的带宽给更高级别的用户,并给予更高的优先级,为更高的权重视频[流行的视频],使他们能够以高的QoS服务,减少了中央多媒体服务器上的负载,并最大限度地提高相邻的代理服务器和中央多媒体服务器之间的信道利用率和较低的视频拒绝率。仿真结果表明,通过相邻代理服务器之间的负载分担,降低了中央多媒体服务器的负载,最大限度地提高了带宽利用率,并为高级别用户分配了更多的带宽。

英文摘要:

This paper proposes a dynamic bandwidth management algorithm in which more bandwidth is allocated for higher class users and also higher priority is given to the videos with higher popularity within a class using agent technology. The popularity and weight profile of the videos which is used for efficiently allocating bandwidth is periodically updated by a mobile agent. The proposed approach allocates more bandwidth for higher class users and gives higher priority for higher weight videos [popular videos] so that they can be served with high QoS, reduces the load on the central multimedia server and maximizes the channel utilization between the neighboring proxy servers and the central multimedia server and lower video rejection ratio. The simulation results prove the reduction of load on central multimedia server by load sharing among the neighboring proxy servers, maximum bandwidth utilization, and more bandwidth allocation for higher class users.
