Aggregate Congestion Control for Video-on-Demand Traffic Transmission


Ping Trunking is an edge-to-edge management technique that can provide some service guarantees to flow aggregates. Each trunk comprises several individual flows running between two nodes in a network at a rate dynamically determined by a Vegas-like congestion control mechanism. A control connection is in charge of regulating the rate at which trunks send their data packets. Ping Trunking is not only able to share the available bandwidth among competing aggregates in a fair manner, but it also can be an effective tool for network operators in managing applications which involve video streaming over IP networks. Video on-Demand (VoD) is expected to be one of the most popular among this kind of applications. In this paper, some simulation experiments have been conducted to evaluate Ping Trunking performance when managing VoD traffic. Simulation results demonstrate that our proposal satisfactorily fulfills VoD network requirements in terms of bandwidth, losses and delay.
