Each year in Manitoba rates of many sexually transmitted and blood born infections (STBBI) are rising, including HIV and hepatitis C. Due to routes of transmission, safer sex and safer drug use information are integral to preventing new infections. Peer delivered information within social networks is considered best practice for engaging, educating, and treating those most vulnerable to STBBI. This community based research project explored how the 595 Peer Working Group shares information on within their social network. Seventeen qualitative interviews were conducted with participants and two quantitative surveys were administered to gather demographic information. The results indicated that 16 of the participants actively pass on safer drug use and safer sex information within their social networks. Additionally, all 17 participants indicated that they distribute harm reduction supplies. Implications from this research highlight the need to increase peer-to-peer knowledge sharing opportunities as well as peer-to-peer distribution of harm reduction supplies.

Peer-to-peer (P2P) applications have become a popular method for obtaining digital content. Recent research has shown that the amount of time spent downloading from a poor performing peer effects the total download duration. Current peer selection strategies attempt to limit the amount of time spent downloading from a poor performing peer, but they do not use both advanced knowledge and service capacity after the connection has been made to aid in peer selection. Advanced knowledge has traditionally been obtained from methods that add additional overhead to the P2P network, such as polling peers for service capacity information, using round trip time techniques to calculate the distance between peers, and by using tracker peers. This work investigated the creation of a new download strategy that replaced the random selection of peers with a method that selects server peers based on historic service capacity and ISP in order to further reduce the amount of time needed to complete a download session.

This work investigated the creation of a new download strategy that replaced the random selection of peers with a method that selects server peers based on historic service capacity and ISP in order to further reduce the amount of time needed to complete a download session. The results of this new historic based peer selection strategy have shown that there are benefits in using advanced knowledge to select peers and only replacing the worst performing peers. This new approach showed an average download duration improvement of 16.6% in the single client simulation and an average cross ISP traffic reduction of 55.17% when ISPs were participating in cross ISP throttling. In the multiple clients simulation the new approach showed an average download duration improvement of 53.31% and an average cross ISP traffic reduction of 88.83% when ISPs were participating in cross ISP throttling. This new approach also significantly improved the consistency of the download duration between download sessions allowing for the more accurate prediction of download times.
