Towards the Flexibility of Software for Computer Network Simulation
Abstract— This paper discusses network simulator TRIADNS. It is well known that the role of computer networks becomes more important due to progress in new computer technologies (distributed information systems, GRID-computing, Cloud computing and so on). So it is necessary to have effective and flexible program tools for computer network design and simulation. Indeed this program tools have to design computer networks with a lot of computer nodes, so simulation run must be time-consuming. Besides, it is necessary to study topological characteristics of computer network, to investigate traffic, to study computing node’s behavior, to test the designed protocols, to study the behavior of routing algorithms and how these algorithms will behave when computer network topology is changed (new nodes can be added to network, some nodes can fail and so on). Network simulator must design and investigate not only hardware, but software too, explore computer networks, considering in particular the specific characteristics of a variety of computer networks.This paper considers approaches allowing to decide these problems: hierarchical model, using ontologies and Data Mining methods for the analyses of simulation results.
