Each channel priority of Emma is determined according to each overlay peer's favor to the channel.…”

Recently multi-channel multimedia broadcast systems on P2P network have emerged in applications such as long-distance education and multimedia broadcast television. With the conflict between huge amounts of streaming data and limited available bandwidth over the Internet seemingly irreconcilable, we observe 1) some channels demand disseminating rapidly, having no requirement for high presentation quality at receivers and 2) some channels expect better quality of service metrics such as bit rate and delay than others while bandwidth contention of multiple channels makes it difficult to realize. Existing proposals have not done enough work based on the two observations. In this paper, we propose DiffStream, a multi-channel dissemination strategy. In DiffStream, each channel disseminates partial streaming data instead of all, using MDC technology. Meanwhile, service differentiation is also achieved by treating different channels with varying priorities and regulating allocation of network resource to different channels in application layer. Furthermore, an extensive mechanism of vacant bandwidth preemption for improving bandwidth utilization is also raised. Experiments are constructed on NS2 and the results have demonstrated DiffStream's effectiveness in achieving our design objectives.

“…Multiple path approaches where the redundant paths are used in case of original path failure ( [5], [6]), or restore schemes where the overlay topology is re-established using a previously or immediately calculated restore mission ( [7], [8], [9]) are often used to realize this. The third one corresponds to the ALM schemes like [10], [11], [12], which are targeted to provide some other QoS features like bandwidth.…”

Abstract-In this paper, we propose a new overlay multicast protocol designed for inter-active multimedia streaming applications. The protocol considers the heterogeneity of end-hosts and tries to minimize the negative impact (data outage) of end-hosts' unannounced departures. For this purpose, it concentrates on endhosts' reliability (lifetime for instance) and constructs a shared tree called ms-DDBMSST (multiple-source Degree and Delay Bounded Maximum Stability Spanning Tree) as an overlay network that involves all the participants of the application, in a distributed manner. For a given set of nodes where some of them are senders, ms-DDBMSST is a spanning tree where the receive path stability of the entire tree is maximized while satisfying the delay-from-source constraint and degree constraint for each node. We believe that this is the first approach that defines ms-DDBMSST construction problem and presents a distributed protocol for the purpose. Our performance evaluation is based on experiments in both simulated networks and PlanetLab that strongly shows the efficiency and usefulness of the proposed protocol.

“…We assume that there exists a node that never disappears, for example, the first member node or a well-known node. Such a node is called the root node 2 . The root node starts the information collection in the collection phase for every (regular) interval by broadcasting synchronization messages on the current tree.…”
