INVESTIGATION OF BATCH DATA FLOW TRANSMISSION PARAMETERS
分析了一个单信道排队系统在传输批量数据流时的性能指标，包括数据包平均停留时间、延迟变化和丢包率，并基于仿真结果提出了改进建议。
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.
