Program tools and language for Network simulation and analysis

This paper considers software tools and linguistic constructions of the network simulator TRIADNS. Nowadays network applications - especially in the area of wireless networks - are becoming more and more complex which makes the design and the testing almost impossible without appropriate software. This software available to aid the user in simulating previously designed scenarios, scalable algorithms and changing structure of computer network. So it is necessary to have effective and flexible program tools for computer network design and simulation. 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. Besides computer networks may include a lot of nodes. This paper discusses approaches allowing to decide the problems mentioned above: hierarchical model, using ontologies and Data Mining methods for the analyses of simulation results, using several computing nodes for computer network simulation (distributed and parallel simulation).
