ANALYSIS OF QUALITY OF SERICE IN MULTISERVICE NETWORKS

This article is devoted to the current issue of the modern IP networks. A significant development of stream traffic in NGN (New Generation Network) has lead to an issue of packet delay. These delays lead to bad quality. The usage of QoS technologies (Quality of Service) is necessary for letting users achieve their goal. QoS is not just a technology, it is a service taking into account business processes. It is a set of tools allowing users to control their networks. QoS guarantees that applications and their traffic correspond to business purposes. The aim of this article is analysis of methods and approaches to quality control in multiservice communication networks and defining advantages and drawbacks of various QoS methods.
