An Easy Matrix Computation Based Simulator of NDN

Abstract

This paper presents an easy matrix computation based simulator of NDN network architecture. This simulator is just like Newtonian mechanics in some way, once given the system initial state, routing table, content distribution, initial data requesting information of NDN network, the simulator can figure out all of the subsequent network state based on matrix operation. This simulator turns packet process event, such as interest generating, interest forwarding, content hitting and transmitting, to matrix computation on the network scale. This simulator is much easier to use than NS3 and CCNx, but it can provide similar simulation result and more details. And the computational complexity depends on number of involved contents and nodes, which makes analysis between small group of nodes and contents very simple and fast.
