SUMMARY:Design and analysis of content caching networks
DESCRIPTION:Today's Internet architecture\, nearly 40 years old now\, is
 grounded in a model of host-to-host communication. More recently\, a number
 of researchers have begun to focus on Content Networking - a model in which
 host-to-content (rather than host-to-host) interaction is the norm. Here\,
 content distribution and retrieval\, rather than host-to-host packet
 delivery\, is the core function supported in each and every network node. A
 central component of proposals for such content delivery is the routing of
 content to requestors through a large-scale interconnected network of
 caches. In this talk we focus on this cache network.\n\nWe begin with a
 quick overview of Content Networking. We then describe Breadcrumbs - a
 simple content caching\, location\, and routing system that uses a small
 amount of information regarding cache history/routing in a simple\,
 best-effort approach towards caching. In the second part of this talk we
 consider the broad challenge of analyzing networks of interconnected
 caches. We describe an iterative fixed-point algorithm for approximating
 cache network performance\, evaluate the accuracy of the approximation\,
 and identify the sources of approximation error. We also consider the
 steady state behavior of cache networks. We demonstrate that certain cache
 networks are non-ergodic in that their steady-state characterization
 depends on the initial state of the system. We describe sufficient
 conditions (based on topology\, admission control\, and cache replacement
 policy) for ergodicity and ergodicity equivalence classes among policies.
 Last\, we describe current work on developing a network calculus for cache
 network flows.\n\nJoint work with Elisha Rosensweig\, Daniel Menasche\, Don
 Towsley.
