A Fluid-Based Model of a Transport Protocol in Content-Centric Networking

Abstract

In this paper, we propose a modeling approach for a Content-Centric Networking (CCN) network by considering the dynamics of its transport layer protocol. Transport layer protocols for CCN have mainly been investigated through simulation experiments because CCN itself is a complicated network architecture compared with IP, and the complex interaction between CCN caching and the behavior of a transport layer protocol must be considered. Several analytical studies of transport layer protocols in CCN have been reported; however, these modeling approaches cannot model the dynamical behavior of a transport layer protocol or a large-scale CCN network. In this paper, by extending an existing large-scale CCN modeling approach, we build a fluid-based model for a CCN network with an AIMD-based window flow control mechanism. Moreover, we verify the validity of our approximate analysis by comparing the analytical results with simulation results.
