 Major content distribution networks, such as Akamai, consider the P2P paradigm as a real threat for their content distribution business. This is because the P2P paradigm may achieve similar services with a fraction of the cost. However, there are several research challenges that need to be addressed to enable the P2P paradigm to achieve this potential. In this research, we tackle these research challenges. Our goal is to develop a fully functional and reliable P2P content distribution system, which we call pCDN. Several steps have been made towards that goal. In fact, we already have a  beta version of pCDN 1.0.
-pCDN will provide high-quality multimedia content, support heterogeneous clients, impose minimal load on the expensive inter-ISP links, provide on-demand as well as live streaming services, ensure data integrity, implement digital rights management, among other features. All features are based on novel algorithms developed by our group.

All features are based on novel algorithms developed by our group. An overview of pCDN and its features can be found in this [http://www.cs.sfu.ca/~mhefeeda/Papers/pCDN07.pdf White Paper.] The white paper also summarizes the main differences between pCDN and common P2P file-sharing systems such as BitTorrent and Gnutella.
 pCDN is developed in partnership with the [http://www.cbc.ca Canadian Broadcasting Corporation] (CBC). CBC is the largest Internet content provider in Canada with millions of online users consuming a huge amount of bandwidth, which costs CBC millions of dollars each year. The objective of pCDN is to offset some of these costs while providing better streaming services to clients. pCDN 1.0 is currently in the final testing phases by CBC to be released to the public. Testing is being performed on small Internet streaming services, and the system will gradually evolve to larger-scale important services.

 We investigate the applicability of the peer-to-peer (P2P) computing paradigm in designing large-scale content distribution systems. The P2P paradigm provides: (i) improved scalability by aggregating resource contributions from peers (end user machines) and reducing the reliance on centralized servers, (ii) reduced cost by utilizing already-deployed resources and eliminating the need for expensive infrastructure, and (iii) rapid deployability by performing all processing at the end systems.
