An Amortized Tit-for-Tat Protocol for Exchanging Bandwidth Instead of Content in P2P Networks
Overview Incentives for resource sharing are crucial for the proper operation of P2P networks. The principle of the incentive mechanisms in current content sharing P2P networks such as BitTorrent is to have peers exchange content of mutual interest. As a consequence, a peer can actively participate in the system only if it shares content that is of immediate interest to other peers. This paper proposes to lift this restriction by using bandwidth rather than content as the resource upon which incentives are based. Bandwidth, in contrast to content, is independent of peer interests and so can be exchanged between any two peers. The paper presents the design of a protocol called amortized tit-for-tat based on the bandwidth-exchange concept.
