An Efficient Local Bandwidth Management System for Supporting Video Streaming

In order to guarantee continuous delivery of video streaming over best-effort (BE) forwarding network, some quality-of-service (QoS) strategies such as RSVP and DiffServ must be used to improve the transmission performance. However, these methods are too difficult to be employed in practical applications since their technical complexity. In this paper, we design and implement an efficient local bandwidth management system to tackle this problem in IPv6 environment. The system monitors local access network and provides assured forwarding (AF) service through controlling the video streaming requests based on available network bandwidth. To assess the benefit of this system, we perform tests to compare its performance with that of conventional BE service. Our test results indicate convincingly that AF offers substantially better performance than BE.
