Optimized Content Caching and Request Capture in CNF Networks

Free registration required

Executive Summary

In order to meet the overwhelming demands of content retrieval for mobile end users, a novel architecture for the next-generation Internet called Cache-and-Forward (CNF) has been proposed to transport content as large "Packages" in a hop by hop manner towards the destination, instead of transporting a stream of small packets along an established TCP/IP connection. In this paper, the authors investigate how CNF network architecture can be designed for efficient content retrieval for wireless mobile nodes. In particular, they look at Integrated Caching in which they assume each CNF router on the future Internet can cache contents that pass by and reply to content requests with its local copy. They name this content delivery method Cachingn-Capture(CC).
