Toward continuous push-based P2P live streaming

Dongni Ren, Wangkit Wong, S.-H. Gary Chan
2012 2012 IEEE Global Communications Conference (GLOBECOM)  
Due to unpredictable peer churns (joins, leaves and failures), it is challenging to offer video continuity in peer-topeer (P2P) live streaming.  ...  In this paper, we study a push-based P2P network formed by unreliable nodes (i.e., nodes which may churn at any time).  ...  Our proposed scheme leads to a highly optimized and adaptive structure with high stream continuity. Another body of work on streaming mesh uses pull-based approach for data exchange [7] .  ...

Churn-aware optimal layer scheduling scheme for scalable video distribution in super-peer overlay networks

Yong-Hyuk Moon, Jeong-Nyeo Kim, Chan-Hyun Youn
2013 Journal of Supercomputing  
To model a layered video streaming system in super-peer overlay networks that faces with heterogeneity and volatility of peers, we formulate a layer scheduling problem from understanding some constraints  ...  We also propose a peer-utility-based promotion algorithm that selects the most qualified neighbor to guarantee the sustained quality of streaming despite high intensity of churn.  ...  To tackle the dynamic churn [2] of multiple supplying peers, first we exploit the super-peer overlay structure [11] , which highly ensures collective availability for large-scale streaming.  ...

An empirical study of the global behavior of a structured overlay network

Ruma R Paul, Peter Van Roy, Vladimir Vlassov
2014 14-th IEEE International Conference on Peer-to-Peer Computing  
Distributed applications built on top of Structured Overlay Networks (SONs) operate based on certain self-* behaviors of the underlying Peer-to-Peer network.  ...  By means of simulations, we demonstrate reversibility for overlay networks with high levels of partition and churn.  ...  As our investigation shows, there are peers whose joining processes fail under churn. With the increment of churn more peers are unable to join the network.  ...

Peer-to-peer (P2P) multimedia streaming provides a scalable solution for IPTV.  ...  In this paper, we devise a simple, yet efficient agent-based P2P streaming scheme, called NAP, which reduces churn-induced delays.  ...  Since agents work in a distributed manner whose amount fluctuates adaptively to the network size, NAP exhibits massive scalability.  ...

Churn-Resilient Replication Strategy for Peer-to-Peer Distributed Hash-Tables [chapter]

Sergey Legtchenko, Sébastien Monnet, Pierre Sens, Gilles Muller
2009 Lecture Notes in Computer Science  
This is true for most current DHT-based system's implementations. To avoid this problem, it is necessary to build really efficient replication and maintenance mechanisms.  ...  We then propose solutions to enhance churn tolerance and evaluate them through discrete event simulations.  ...  Impact of the churn on the DHT performance A high churn rate induces a lot changes in the P2P network, and the maintenance protocol must frequently adapt to the new structure by migrating data blocks.  ...

2010 2010 European Dependable Computing Conference  
This paper integrates a structured P2P overlay and a Random Peer Sampling service through gossip protocols.  ...  DHTs achieve efficient lookup while RPS enables nodes to build and maintain connectivity in the presence of high churn.  ...  We simulate a 10, 000-node network under different churn conditions. At each cycle, a fixed amount of nodes leaves the network and the same amount of new nodes joins.  ...
