Imitation Modeling of Control Providing Processes of Intelligent Services in NGN

The article is devoted to the development of imitation models of control providing processes of intelligent services in NGN. It is shown that in order to determine the effectiveness of control of providing intelligent services by various authors, a number of analytical models of intelligent superstructures are proposed both without consideration and taking into account the self-similarity of the flow of applications to intelligent services. It is noted that the creation of analytical models with a significant complication of intelligent superstructures becomes virtually impossible. In this case, it is suggested to use imitation models. It is proposed to present the intelligent superstructure as a queuing system. To model the intelligent superstructure of NGN in the form of queuing system without taking into account the self-similarity of the flow of requests for intelligent services, it was decided to use the GPSS system. To model the c superstructure taking into account the self-similarity of the flow of applications, it is proposed to use the system "Network Simulator-2" (NS-2). The algorithms of functioning and imitation models of intelligent superstructure are presented, which provides one class of applications without taking into account the self-similarity of traffic intelligent superstructure, which provides three classes of applications with relative priorities and without taking into account the self-similarity of traffic, and the intelligent superstructure, taking into account the self-similarity of the flow of applications for intelligent services. By using imitation models without account and taking into account the self-similarity of traffic for intelligent superstructure that serves one class of applications for intelligent services, the quality criterions provided by intelligent services are determined, which provides an opportunity to gauge the efficiency of control of provision of intelligent services. The proposed imitation models will allow the NGN design stage to determine the effectiveness of control the provision of intelligent services with an intelligent superstructure.
