Abstract
The work proposes and investigates an intelligent method and algorithms for on-line assessment of the state of network elements to ensure the required quality indicators of provided communication services in corporate high-speed multiservice communication networks. The developed method and algorithms operate in a mode close to real time. One of the features of corporate multiservice communication networks is the high dynamics of changes in their state. The main task of the automated control system, which is an integral part of the corporate multiservice communication network, is to ensure the specified quality of the provided communication services to the consumer. Thus, the relevance of the research presented in the work is due to the fact that most of the management processes in corporate high-speed multiservice communication networks must be implemented in a mode close to real time with a given quality. The basis of the method for operational assessment of the state of network elements is the concept of creating and using intelligent agents. In the proposed approach, intelligent agents are created as hierarchical fuzzy situational networks, in which control solutions, in contrast to known methods based on the use of reference situations, are applied based on solving a hierarchical set of optimization problems using fuzzy mathematical programming methods. The main paradigm of their functioning is “situation -action”.
Highlights
The intensive development of transport and logistics systems, industry, as well as business is characterized by the successful use of corporate multiservice communication networks (CMCN), which provide users with the provision of various infocommunication services
The functional basis of CMCN is the technology of telecommunications and new generation networks (NGN), the core of which is packet networks based on the TCP/IP/MPLS protocol stack, which integrate various communication services [1,2,3,4]
The studies carried out have shown that the estimation of the average delay in servicing a claim and its transmission to the communication line is made with an average relative error of less than 10%
Summary
The intensive development of transport and logistics systems, industry, as well as business is characterized by the successful use of corporate multiservice communication networks (CMCN), which provide users with the provision of various infocommunication services. They are due to the complexity and large spatial scope of CMCN network infrastructure, its heterogeneity, the need for a quick and high-quality analysis of a large number of various dynamically changing network and information parameters and characteristics for making management decisions, which, in turn, have inaccuracy, uncertainty and fuzziness. The noted features of the CMCN functioning and the process of its management determine the need for the development and application of intelligent methods for the operational development and implementation of managerial decisions on managing the quality of communication services of CMCN. This determines the need to develop such methods, which is an urgent scientific problem
