Congestion Control Using Diffusion Method in Named Data Networking

Abstract

Named Data Networking (NDN) is a new networking mechanism to amend problems in the current Internet. There are many features to improve the efficiency of network in NDN, and one of them is that routers can cache data conveyed by packets. This results in network node to client communication unlike the client to client principle in TCP/IP architecture. Therefore, end-to-end flow control cannot be applied to NDN unlike the Internet. Inspired from thermal diffusion, researchers proposed hop-by-hop flow control to solve this problem. However, the congestion control in hop-by-hop method is still under research. In this paper, a diffusion-based flow control method for NDN is proposed. We conducted simulations to verify its performance.
