CALCULATING METHODS OF THE CHARACTERISTICS QUALITY OF SERVICE FOR NON-UNIFORM TRAFFIC IN MULTISERVICE COMMUNICATION NETWORKS

Abstract

Practical measurements traffic of telecommunication network found that the real traffic is significantly different from the model a Poisson stream and therefore to calculate the quality of service it is necessary to other methods that are different from the known and adequate to the new patterns of traffic. The nature of the flow of these traffic flows and their maintenance depends on the specific type of system (hub or multiplexer), network sections (subscriber or transport) and many other factors. Some of the problems of analysis and synthesis of information distribution systems can be solved using the theory of mass service using methods of modern mathematics. The entire package of tasks for calculating information distribution systems for any of its schemes and service disciplines is solved only for the case of a simple mathematical traffic model - the Poisson stream of applications. For this model, all analytical formulas are known for calculating the main characteristics of the quality of service in information distribution systems. However, for models of multiservice traffic, only partial results or inaccurate methods of calculating the quality of service were obtained, which makes it impossible to use them in the design of telecommunication systems and networks operating in real traffic conditions. In the paper systematized new methods of calculation and design of telecommunication systems and networks and offered recommendations on how to use them.
