Abstract
Rapid growth and increasing requirements for service quality, reliability, and efficiency have made traffic evaluation an essential consideration in design and operation of data transmission networks. In this paper we analyse performance measures of data transmission network servicing batch data flows. The article provides analysis of the one channel queuing system transmitting data packet flow general distributed. In this article we introduce queuing system with finite and infinite buffer capacity. In this article we analyse such data packets transmission performance parameters: average time spent by data packet in system, data packet delay variation, data packet loss. The data packet arrival rate and channel data packet transmission rate are independent of system state. A key mechanism of the proposed traffic model is that packet time spent in the system depends on channel utilization level, packet flow type and size of transmitted data. The proposed simulation model can be used when packet interarrival time follows such distributions: Pareto, Poisson, uniform, normal distribution. Simulation results of performance measures are defined by mathematical models. Considering simulation results recommendations were proposed to improve performance measures for batch data flow transmission over data networks.

Summary
A network operator must decide what services the network should deliver to the end user and the level of service quality that the user should experience This is true for any telecommunications network, whether it is circuit or packetswitched, wired or wireless, optical or copper-based, and it is independent of the transmission technology applied. Role for the modelling is to expose properties of measurements that are important for particular engineering problems. This can happen when parameters are interpretable. In cases where parameters are interpretable, data or simulation models allow asking ‘what if’ questions. Our proposed simulation model can be used to analyse the main data packet flow transmission performance parameters
