Abstract: There has been proposed the method for evaluating the routing cost which is based on the account of fractal properties of the network traffic and pre-set limits for the latency time and the number of lost packets. This method calculates the fractality of the traffic and the value of bursts. Depending on these parameters, the routing costs are recalculated and the optimal one is chosen for transferring. If the traffic is the usual Poisson flow, then the routing is not changed. If the traffic has strong long-term dependence and high bursts, then the routing cost increases in proportion to the value of Hurst exponent and the extend of bursts. The proposed method for evaluating the routing cost with regard to fractal properties of the traffic has been tested on an open platform of graphical simulation of HUAWEI networks in the existing network of “Market-port” company. During the experiment the network parameters have been defined (bandwidth, load capacity of the channels, the number of lost data, transmission delays, fractality) in the real “Market-port” network. Then the network similar to a real one has been modelled and configured in such a way that transmission time, the number of lost packets, the average latency time of the packets in the network coincides with the data having been defined in a real network of “Market-port” company. The source of the implementations of traffic in the experiments was the realization of the real network traffic captured in the network of “Market-port” company and the model implementation generated by these parameters. The studied simulation of the proposed method for evaluating the routing cost in MPLS network has shown that the use of the developed method significantly improves the quality of the service, reduces the transmission losses and permits to load network channels more evenly.
