Queuing model of the access system in the packet network

Abstract

This article proposes a new multi-dimensional Erlang’s Ideal Grading (EIG) model with queues that can service a number of call classes with differentiated access to resources. The model was used to determine delays and packet loss probabilities in the access system composed of a node in the operator’s network and a number of users. The analytical results obtained in the study were then compared with the results of a simulation, which confirmed the essential and required accuracy of the proposed model. The model developed in the study can be used to analyse, design and optimize present-day operator’s networks.
