iGridMedia: Providing Delay-Guaranteed Peer-to-Peer Live Streaming Service on Internet

2009 6th IEEE Consumer Communications and Networking Conference

2009

P2P-based IPTV service delivery is considered as the next killer application over the Internet. P2P systems address the issues of scalability and are considered most suitable architecture for the real-time content distribution/sharing. On the other hand, P2P applications show greedy behavior in the consumption of available network bandwidth and leads to the problems of inefficient utilization of network resources and poor interactions with other applications. These problems are due to the lack of coordination among service providers (SPs) and P2P applications. Thus, in this paper, we present a SP-driven P2P framework for the IPTV Service delivery to facilitate the service delivery mechanism with improved Quality of Services (QoS). The proposed mechanism is assisted by the explicit communications among SPs and P2P applications for efficient utilization of available resources. The proposed mechanism also addresses the issues related to QoS provisioning and the nonlinear service distribution.

Abstract-In this paper we propose SWOR, an architecture to deliver Scalable Video Coding (SVC) contents over P2P network. SWOR architecture is based on twofold mechanisms: (1) organization of peers in Small-World (SW) overlay networks, (2) delivering SVC content using push-pull mechanism. SWOR is evaluated and compared with CoolStreaming/DONet (CS) on QoS metrics using NS-2 simulator. Performance evaluation demonstrates that SWOR outperforms CS and provides a significant improvement in the received video quality in terms of lowering the packet loss and transmission delay.

K-overlay: A Kautz Tree Structure for Video on Demand System

2010 Ninth IEEE International Symposium on Network Computing and Applications

2010

Abstract-In order to improve scalability and reduce maintenance overhead for Peer-to-Peer system, several architecture with constant degree and optimal diameter are proposed. However, the expected topology doesn't effectively utilize the bandwidth capacity of peers. In this work, we propose K-overlay, an overlay scheme based on unbalanced Kautz graph with logd n diameter and constant in-degree. We define the degree of a digraph as the maximum number of arcs arriving at or leaving from any vertex. The diameter of a graph is the number of arc traversals that is sufficient to reach any vertex from any other vertex. K-overlay structure is based on two-fold mechanism. (1) Organization of peers in concentric circles to maximize the outgoing bandwidth of peers (2) Content delivery through parent as well as neighboring peers. Through formal analysis and comprehensive simulations, we show that our proposed architecture achieves optimal diameter and good connectivity as compared to existing overlay architecture like P2Cast.
