Peerialisms paper on The Feasibility Of Centrally-Coordinated Peer-To-Peer Live Streaming has been accepted by the IEEE Consumer Communications and Networking 2011 conference. At the conference, Peerialism will demonstrate its Peer2View platform which introduces elements of central control and coordination for efficient and reliable live streaming content distribution.
Peerialism will also conduct a demo of its P2P application level emulator, MyP2PWorld, showing how tracker and optimization components work and which gains can be realized by introducing coordination in a P2P system in terms of bandwidth savings, ISP friendliness, and reliable NAT traversal. The demo will touch upon Peerialism’s approach to P2P systems development and how it greatly benefits from application level emulation.

When evaluating Peer-to-Peer content distribution systems by means of simulation, it is of vital importance to correctly mimic the bandwidth dynamics behavior of the underlying network. In this paper, we propose a scalable and accurate flow-level network simulation model based on an evolution of the classical progressive filling algorithm which implements the max-min fairness idea. We build on top of the current state of art by applying an optimization to reduce the cost of each bandwidth allocation/deallocation operation on a node-based directed network model. Unlike other works, our evaluation of the chosen approach focuses both on efficiency and on accuracy. Our experiments show that, in terms of scalability, our bandwidth allocation algorithm outperforms existing directed models when simulating large-scale structured overlay networks. Whereas, in terms of accuracy we show that allocation dynamics of the proposed solution follow those of the NS-2 packet-level simulator by a small and nearly constant offset for the same scenarios. To the best of our knowledge, this is the first time that an accuracy study has been conducted on an improvement of the classical progressive filling algorithm.

Peerialism delivers Peer2View – a platform for over-the-top video streaming – to MPS Broadband. Peer2View is a p2p assisted distribution solution for video streaming of live events and linear TV over internet. Peer2View is designed to work with existing CDNs to greatly improve scalability, reach and distribution efficiencies. The solution can handle a large number of simultaneous users whilst maintaining a high quality of service meeting the requirements of commercial content owners.
The solution has two main components a client running on end users’ computers, and a server that tracks the state of the Peer2View network and optimizes client network connections. Peer2View uses network resources more efficiently and has the following commercial advantages:
Bandwidth savings: Depending on network conditions, the bandwidth savings can be up to 95%
Larger number of concurrent users; with a limited investment a Peer2View assisted CDN can easily reach several hundreds of thousand viewers
More channels: High savings rates can be reached with relatively few peers – 500 peers will typically produce 90% savings. Thus many channels, including niche channels can be distributed in parallel without exhausting the capacity of the network
ISP and Internet friendly algorithms keeping traffic local
