Enhancing reciprocity has been one of the primary motivations for the design of incentive policies in BitTorrent-like P2P systems. Reciprocity implies that peers need to contribute their bandwidth to other peers if they want to receive bandwidth in return. However, the over-provisioning that characterizes today’s BitTorrent communities and the...

Many private BitTorrent communities employ Sharing Ratio Enforcement (SRE) schemes to incentivize users to contribute their upload resources. It has been demonstrated that communities that use SRE are greatly oversupplied, i.e., they have much higher seeder-to-leecher ratios than communities in which SRE is not employed. The first order effect...

Many peer-to-peer communities, including private BitTorrent Communities that serve hundreds of thousands of users, utilize<br/>credit-based or sharing ratio enforcement schemes to incentivize their members to contribute. In this paper, we analyze the performance<br/>of such communities from both the system-level and the user-level perspectives....

Many private BitTorrent communities employ Sharing Ratio Enforcement<br/>(SRE) schemes to incentivize users to contribute. It has been demonstrated<br/>that users in private communities are highly dedicated and that they seed much<br/>longer than users in communities where SRE is not employed. While most pre-<br/>vious studies focus on showing...

User interactions are indispensable for any online network to thrive, especially for BitTorrent‐like and Web real‐time communication‐based distributed online networks that rely on users' collective contributions instead of the help of central servers. User interactions provide fine‐grained information for many applications, such as security...
