Analysis and modelling of heterogeneous similar traffic of computer networks

DOI №______

Abstract

The models of computer networks heterogeneous traffic with selfsimilar characteristics are analysed. For the removal of batch property traffic, that is caused by selfsimilarity of input streamthat, it is necessary to manage his parameters, in the first turn the period of receit of packets. Due to it speed of growth of turns in buffer memory of switchboard knots is slowed. As a result, the risk of congestion of separate routes and autonomous network segments goes down. The main directions of subsequent researches are formulated: receipt of quantitative estimations of necessary volumesof annex memory and delays of treatment of traffic in accordance with imes of packet life. The calculations results of basic technical and economical indicators of network for the different input traffic models are resulted. A comparative analysis is executed both for the poissons and for the similar streams

Keywords: computer network, selfsimilar traffic, congestion, queueing system theory, multichannel system, Little formula, Herst parameter.
