Successful networked systems must account for potentially competing interests.  In this talk, I will present two systems that together demonstrate that economic theory, and in particular auctions, can be a powerful means of analyzing and improving incentives for self-interested users to cooperate.<\/p>\n<p>First, I will show that the popular BitTorrent system uses, not tit-for-tat as widely believed, but an auction to decide which peers to serve.  This model captures known performance-improving strategies, and shapes our thinking toward new, effective incentive mechanisms.<\/p>\n<p>Second, I will present Hoodnets, a system that allows mobile phone users to bond their low-bandwidth cellular connections into high-bandwidth connections. Hoodnets employs auctions to give users incentive to forward traffic for one another, overcoming the likely reluctance of sharing their costly links.  With a real-world implementation of Hoodnets, I will demonstrate that, in practice, two complementary auction mechanisms are necessary to support both long-lived flows and bursty traffic.<\/p>\n<p>These two systems together demonstrate the importance of aligning the assumptions of economics and large-scale systems.  Doing so allows us to develop new mechanisms that foster cooperation among the otherwise self-interested.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Internet is no longer the cooperative, technological playground it once was.
