Stable Content-peering of Autonomous Systems in a Content-centric Network
2013 (English)Conference paper, Presentation (Refereed)
A future content-centric Internet would likely consistof autonomous systems (ASes) just like today’s Internet. It wouldthus be a network of interacting cache networks, each of themoptimized for local performance. To understand the inﬂuence ofinteractions between autonomous cache networks, in this paperwe consider ASes that maintain peering agreements with eachother for mutual beneﬁt, and engage in content-level peering toleverage each others’ cache contents. We propose a model of theinteraction and the coordination between the caches managed bypeering ASes. We address whether stable and efﬁcient contentlevel peering can be implemented without explicit coordinationbetween the neighboring ASes in order for the system to bestable. We show that content-level peering leads to stable cacheconﬁgurations, and that avoiding simultaneous updates by peeringISPs provides faster and more cost efﬁcient convergence to a stableconﬁguration. We validate our analytical results using simulationson the measured peering topology of more than 600 ASes.
