<p>Context. The problem of growth of the mobile data traffic and the number of services becomes global, moreover, volume and frequency<br />of control traffic transmitted through the network are increasing, and therefore there is a need for its effective management to ensure the<br />quality of service required by users and optimal use of mobile network resources. In such circumstances, the load on the server that is created<br />in the process of establishing the connection and its serving has its considerations. Dynamic resource provisioning is a useful technique for<br />handling the variations seen in communication systems workloads. Virtualization technology allows to implement this approach. An analytic<br />model of a system would be attractive as it would be able to evaluate system characteristics under a wide range of conditions, and to be computed comparatively easily. It is also can incorporate numerical optimization techniques for system design.<br />Objective. To improve the efficiency of mobile network through optimal resource allocation in telecommunication environment.<br />Method. Analysis of the known publications devoted to virtualization of network functions of mobile network has shown the modeling<br />approach to resource allocation and also has shown the absence of decisions on important issues of this process (performance of management, load prediction system).</p>Results. An approach to model and investigate hybrid dynamic system of network functions resource management, where resources are<br />provided to virtual nodes dynamically and opportunistically based on predicted needs, is proposed.<br />Conclusions. In the paper the problem of provisioning system design for virtualized network functions is solved. A method for adapting<br />the size of network function’s resource allocation control interval is proposed that provides dynamic configuration of the system, reducing<br />excessive service data transmitted in the network, and decrease the load of network nodes. The workload service system model is built which<br />outlines a method of workload forecasting, which takes into account long-term accumulated statistics and recent trends observed in a network that allows a rational level of management costs and final values of quality of service.<p> </p> |
