“…2 as: α = 1.03 and β = 300s. The choice of the value of α is guided by Wang et al in [19] using traces of PPLive, which is a popular P2P live streaming system. They have shown that the node's stay duration of PPLive is well approximated by a Pareto distribution of α = 1.03.…”

Abstract. Internet Coordinate Systems (ICS) provide easy and practical latency predictions in the Internet. However, peer dynamics (i.e, churn), which is an inherent property of peer-to-peer (P2P) systems, affects the accuracy of such systems. This paper addresses the problem of churn in an ICS without landmarks, like Vivaldi. We propose a framework to assess the robustness of such an ICS in the presence of churn, and evaluate two models for handling churn. The key idea is to reactively recover lost neighbours, either by picking new nodes at random, or by selecting a new one among the node's two-hop neighbours, while maintaining high reliability and low communication overhead. We then show by simulations that our models mitigate the impact of churn, and lead to a good accuracy compared to an instance of an ICS running without churn.

Peer-to-Peer (P2P) video delivery using substreams supports uplink heterogeneities of the peers and hence could optimise sharing capabilities with minimum free-riding peers. Therefore, substream-based applications such as PPLive and CoolStreaming have been well accepted after successful deployments in the public Internet. In this approach, a child peer can find a parent peer for a substream independent of the other parent peers that it receives the remaining substreams. In general, there can be more than one substream between a parent and a child. The block-aware adaptation algorithm in CoolStreaming changes the parent peer for all such substreams when a child peer experiences poor performance even on one of its substreams from the parent. However, lagging of one substream in such a scenario is likely while others are not affected, when the parent receives its substreams through multiple paths. We propose a fine-grained approach (changing substream by substream) in peer adaptations to improve overlay network performance. This approach will in turn, is designed also to minimise the diversity of parents at the child peer by joining with a well-performing another parent, which is expected to curtail complexities in a network-assisted P2P framework.

“…Peers establish the parent-child relationships and sub-streams are pushed from parents to their children. mTreebone [13] constructs a single tree with stable nodes rooted at the server and delivers video via a combination of pushing through the tree and pulling through the underlying auxiliary mesh. To assess the stability of nodes, it needs to know the lifetime of the channel beforehand ??.…”

Enabling broadcast of user-generated live video without servers

We are witnessing the unprecedented popularity of User-GeneratedContent (UGC) on the Internet. While YouTube hosts pre-recorded video clips, in near future, we expect to see the emergence of UserGenerated Live Video, for which any user can create its own temporary live video channel from a webcam or a hand-held wireless device. Hosting a large number of UG live channels on commercial servers can be very expensive. Server-based solutions also involve various economic, copyright and content control issues between users and the companies hosting their content. In this paper, leveraging on the recent successes of P2P video streaming, we study the strategies for end users to directly broadcast their own live channels to a large number of audiences without resorting to any server support. The key challenge is that end users are normally bandwidth constrained and can barely send out one complete video stream to the rest of the world. Existing P2P streaming solutions cannot maintain a high level of user Quality-of-Experience (QoE) with such a highly constrained video source. We propose two strategies to address this challenge. We first propose a proactive-push based source-side scheduling algorithm to increase the scale of P2P broadcasts that can be driven by end users. We then propose a novel layered P2P streaming architecture that introduces peer playback delay differentiations to further boost end users' capability of driving large-scale video streaming. Through detailed packet-level simulations and PlanetLab experiments, we show that the proposed strategies enable a source with upload bandwidth slightly higher than the video streaming rate to stream video to tens of thousands of peers with premium quality of experience.
