Abstract

The allocation of bandwidth for multimedia traffic poses a technical challenge due to bursty and isochronous nature of applications. We propose a mobile agent based approach for bandwidth allocation in multimedia communication. It is based on the the network congestion monitored by the agents at the clients. The mobile agent hosted by the server will allocate bandwidth online to the applications within the requested range at regular intervals. Also, it keeps the aggregated bandwidth below the link bandwidth of server and clients. The approach reduces the network control traffic used in traditional online bandwidth allocation policies. The scheme is simulated and its performance is evaluated in terms of several parameters, like, bandwidth utilization, application rejection, agent response time, and agent migrations. The simulation results show that the use of agents increase flexibility and efficiency in end-to-end bandwidth allocation and operate asynchronously. The flexibility in using this technology is that, the allocation policies can be changed, customized and implemented easily.

基于移动代理的多媒体通信在线带宽分配方案

由于应用程序的突发和同步特性，多媒体流量的带宽分配提出了一个技术挑战。提出了一种基于移动代理的多媒体通信带宽分配方法。它基于代理在客户端监控的网络拥塞情况。由服务器托管的移动代理将定期为请求范围内的应用程序在线分配带宽。此外，它使聚合带宽保持在服务器和客户端的链路带宽以下。该方法减少了传统在线带宽分配策略中的网络控制流量。对该方案进行了仿真，并根据带宽利用率、应用拒绝、代理响应时间和代理迁移等几个参数对其性能进行了评估。仿真结果表明，代理的使用提高了端到端带宽分配的灵活性和效率，并实现了异步操作。使用该技术的灵活性在于，可以很容易地更改、定制和实现分配策略。
