DMF: A Dynamic Multi-Path Forwarding Strategy for Information Centric Networks

Abstract

Information-Centric Networking (ICN) is a promising future network architecture where content instead of its location becomes the core of the communication model. Content is independent from location, which enables in-network caching and sharing. The content delivery is based on the content name instead of its address, and it is connectionless. An efficient forwarding strategy is significant for taking maximum advantage of multiple simultaneous connectivities. In this paper, we propose a Dynamic Multi-path Forwarding (DMF) strategy for ICN. DMF adopts RTT as metric at the initial phase and adopts the available bandwidth as metric at the saturated phase to make full use of multiple available transport paths and improve the receiving rate of the consumer. Simulation results show that DMF has better performance compared with existing multipath forwarding strategies proposed for ICN.
