MODELING OF PROCESS PACKET DATA TRANSITION

The work presents a model of the process of a packet transmission of data over a computer network in the form of coloured Petri nets. The mathematical description of the model consists of the transfer of the sets of resources and their interaction. In the developed model, the transfer of information from one computer (the source) to the other four computers (receivers) by taking into account the retransmission of the packet from the transmitter to the receiver in the event of failure. If the successful transfer of the package is formed by the «receipt» with indication of the time of delivery of the package. The model assumes that the request the transmitter to the readiness of the receiver accept the information included in the first package, and in the latter delivered package contains the information for the termination of session of transmission. The structure of the package also conditionally simplified. The developed model can be easily modified, that allows to estimate the time spent in the various modes of transmission. The results are presented more than 100 experiments, which allow to estimate the time and reliability of the transmission of packets.
