Content Replication and Delivery in Information-Centric Networks

Information-centric networking (ICN) is emerging as the main future networking environment, given that the vast majority of Internet activities are related to information access and delivery. This chapter presents a three-phase framework as a contribution to the problem of information replication in an ICN environment, through the synergy of ICN with content delivery network (CDN) techniques. The objective of the presented framework is to minimize the total traffic load in the network subject to installing a predefined number of replication devices. The presented framework comprises three phases, namely, the Planning, the Offline Assignment, and the Online Replacement phases, which manage the content and the location of each replication device in the network. The numerical results provided in the chapter provides evidence that network-wide knowledge and cooperation give significant performance benefits and reduce the time to convergence at the cost of additional message exchanges. © 2014 by John Wiley & Sons, Inc.
