Abstract
This paper presents a multi-service model of a communications system with stream and elastic traffic. The idea of the model is based on an analysis of a two-dimensional Markov process, which approximates the real process in the considered system. Such an approach allows us to describe the use of system resources by stream and elastic traffic with high accuracy. An appropriate simulation model has been developed and implemented in order to verify the proposed model. The presented results have confirmed the validity of all the theoretical assumptions adopted in the study.
Highlights
Data traffic in modern networks is based on the IP protocol
In order to verify the accuracy of the proposed model of a system with stream and elastic traffic, the model’s results were compared with the results of simulation experiments
SUMMARY The presented paper proposes an analytical model of a communications system with a mixture of stream and elastic traffic
Summary
Data traffic in modern networks is based on the IP protocol. Recently, attempts have been made to send various data streams (with different QoS (Quality of Service) requirements) using the IP protocol, e.g., voice (Voice over IP). In the analysis of the service process of the considered system, the traffic resources can be divided into two areas: the uncompressed service area (here referred to as the real area) and the compressed area (here referred to as the virtual capacity), where the calls of elastic traffic undergo compression.
