Analyzing Peer-to-Peer Traffic's Impact on Large Scale Networks [chapter]

Mao Yang, Yafei Dai, Jing Tian
2006 Lecture Notes in Computer Science  
Currently, peer-to-peer file sharing systems are playing a dominant role in the content distribution over Internet.  ...  Therefore understanding the impact of peer-to-peer traffic on large scale networks is significant and instrumental for the design of new systems.  ...  B) Locality-aware on No free-rider condition: free-rider refers to the peer does not upload any file to other peer even if he has some content.  ...

Network aware P2P multimedia streaming: Capacity or locality?

Xin Jin, Yu-Kwong Kwok
2011 2011 IEEE International Conference on Peer-to-Peer Computing  
Index Terms-Peer-to-peer multimedia streaming, traffic locality, inter-AS traffic, network awareness, unstructured overlays.  ...  We find that network awareness in terms of both capacity and locality potentially degrades system QoS as a whole and that capacity awareness faces effort-based unfairness, but enables contribution-based  ...  Thus, directly applying the idea of peer locality to existing P2P streaming systems is non-trivial.  ...

LAN-awareness

Zhijie Shen, Roger Zimmermann
2011 Proceedings of the 21st international workshop on Network and operating systems support for digital audio and video - NOSSDAV '11  
Recognizing the opportunity of localizing traffic within LANs, we discuss the principles to construct a LAN-aware overlay and propose a heuristic.  ...  First we conduct a large-scale measurement on PPLive, confirming that a considerable number of peers (up to 21%) are connected to the LANs having 2 or more peers.  ...  Acknowledgments This research has been funded in part by A*Star grant 082 101 0028.  ...

Analytical Modelling of Localized P2P Streaming Systems under NAT Consideration

Mohammad Z. M. Masoud
2013 International Journal of Computer Networks & Communications  
In this work, we are going to study the impact of NAT types on the start-up delay time of peers in P2P streaming systems.  ...  We will demonstrate the ability of NATing to expel peers in P2P live streaming systems. A new neighbour selecting algorithm will be proposed.  ...  to expel peers from P2P live streaming system, we need to understand how this can happen.  ...

2009 Peer-to-Peer Networking and Applications  
We also provide insights on the potential ways to construct more efficient P2P VoD systems (e.g. considering topological locality-awareness, using adaptive/layered video).  ...  Our extensive experiments prove that Joost is a server-assisted peer-to-peer VoD system.  ...  In the last scenario, it would be interesting to see if the locality-awareness has been carefully considered in Joost system.  ...
