Fluid-Based Modeling of Transport Protocol in Large-Scale Content-Centric Networking

摘要

In this paper, by utilizing fluid approximation, we develop a fluid model for a CCN (Content-Centric Networking) network comprised of multiple entities, multiple routers, and multiple repositories, at the transport level. Since CCN is a more complicated network architecture than IP ana the complex interaction among content caching, Interest packet aggregation, and the behavior of a transport protocol must be considered, CCN requires more complicated modeling approach than IP. In the literature, several mathematical analyses of transport protocol for CCN have been performed. However, these mathematical analyses cannot be utilized to analyze the dynamics of transport protocols in CCN because these studies focus on steady state characteristics. In this paper, we develop a fluid model of a large-scale CCN network, by constructing network component models (i.e., entity, router, and repository) with uniform inputs and outputs (i.e., receiving and sending rate of Interest packets and Data packets).
