Analytical characterisation of multi-path content delivery in Content Centric Networks

Abstract

Content Centric Networking (CCN) is an evolving paradigm in networking where communications are based on named content rather than the named hosts model of today's networks. Though CCN is capable of multi-path communications by design, no work has been done to characterise multi-path content transfers in CCN with an analytical model. In this work, we have developed an analytical model to evaluate the performance of multi-path content transfers in CCN. The performance of this model is then compared against a packet level CCN simulator built in OPNET. Round trip times, throughput and download times are obtained for both multi-path and single path to make comparisons of performances. The comparisons indicate that the results obtained from the simulator are in agreement with the results of the analytical model.
