Abstract
Currently, operators use various methods for evaluating the quality of communication networks built using packet switching technology. At the same time, the methods used do not always fully satisfy the requirements of regulatory documents in the field of assessing the quality of network performance due to the absence of the use of the control method of all necessary quality indicators or the perform of control of quality indicators on a limited network segment along the path of packet traffic. This situation requires a comprehensive assessment of the quality of the network using a set of methods that complement each other to ensure «end-to-end» control on all sections of the network for all necessary quality indicators A rather big problem is the discrepancy between the results of quality control of the provision of specific communication services and the results of quality control of the communication network for the transmission of packet traffic in the interests of a particular network service or the network as a whole. Such inconsistencies can be reasonably well explained by the rather «narrow» problems that are solved using each specific control method at the corresponding levels of the OSI model. The elimination of disagreements in the results obtained for various control methods is possible by creating some generalized methodology to ensure simultaneous monitoring of the quality of the communication network for the transmission of packet traffic and the quality of the provision of communication services. In this regard, the task arises of creating a set of methods that allow to assess the quality of communication networks in accordance with existing regulatory documents and ensure that the procedure for monitoring network and service quality indicators is fully covered.
Keywords:packet communication network, quality indicators, intrusive method, non-intrusive method.
