2008 Second International Conference on Future Generation Communication and Networking
Multicast Congestion Control on Many-to-Many Videoconferencing
December 13-December 15
ISBN: 978-0-7695-3431-2
Congestions in many-to-many videoconferencing are usually caused by multiple senders. Judging the congestion links and determining the adjusting bit rate of senders which caused the congestions are the two issues in congestion control. In this paper, we propose one multicast congestion control scheme based on packets transmission model of shared multicast tree. The end-to-end packet loss rates are measured to get PLR matrix for judging congestion links via tomography method. The bit rates of senders which cause congestions are adjusted to implement congestion control according to the packet loss rate of congestion links with sender-fairness. Simulations and experiments show the scheme is valid and effective.
