Method of controlling access to intellectual switching nodes of telecommunication networks and systems

I. DEFINITION OF PROBLEM In current conditions of dynamic development of various approaches of the analysis and synthesis of the telecommunication networks integrated into information and telecommunication technology [1-5] there are questions of elaboration and application of the general methods of ensuring service quality based on allocation of separate classes of quality and realization of managing algorithms, such as prioritization of information packages, reservation of telecommunication resources, organization of queuing in switching nodes etc. The manifestation of new destabilizing factors associated with the influence of the malicious software on the process of the functioning of information and telecommunication networks obliges to revise the general capabilities of the existing mechanisms for managing the service quality and putting suggestions (algorithms) and adapting them with possible wrongful action of participants of telecommunications exchange. Thus, there is a need to develop networking and communications technologies and to elaborate the methods of managing network resources that could provide: service quality and information security at the joint transfer of heterogeneous traffic, taking into account the constraint of network resources, the real reliability of telecommunications equipment and possible external influence malicious or other character ; Safety of functioning of individual nodes of information and telecommunication system from the effect of malicious software;
