Determination of Criteria for Choosing the Best Ways and Indicators of Service Quality in Infocommunication Networks

The state of channel is suggested to characterize the values of the controlled descriptions, and the change of capacity of channel is presented as a change of some objective function. It is suggested to use the method of gradient prognostication for prognostication of the state of channel. Parameters that characterize the state of discrete channel are analysed. It is set that the devices of control must take into account group character of errors in communication channels and, due to it, control efficiency will rise. The methods of estimation of quality of discrete channels are considered. An algorithm that is suggested to use in a network with commutation of packages during organization of access of streams restriction in a network is described. Possibility of choice of optimal ways is considered on the basis of general and partial criteria of optimization. The methods of measuring of loading and indexes of quality of service are analysed. At measuring of loading it is expedient to use the continuous method of measuring and method of scan-out. In networks with commutation of packages at measuring of different indexes of quality of service (numbers of reports, packages that expect service, to time of expectation of beginning of service and T.Д) it is expedient to use the methods of the direct counting out of number of reports.
