Bandwidth Allocation for Quality of Service Guarantees in Multi-party Multimedia Application

摘要

In this paper, we propose a resource allocation technique where a new stream can preempt some appropriate amount of bandwidth from other existing streams, considering both quality and priority requirements of users. In our method, the user of each stream gives a function representing the quality value to be lost when the allocated bandwidth is preempted and the value representing the priority to other streams. Then we calculate the preemptable band- width from each stream where the total amount of the quality loss in the streams could be minimized. We have implemented the proposed method and evaluated it through the experiment using MPEG1 streams and it is shown that the proposed technique can keep a high frame rate for each MPEG1 stream in existence of a lot of streams.
