Abstract
<p class="20CxSpFirst"><em>The object of the research is the processes of managing resources of queues in network devices of telecommunication networks. </em></p><p class="20CxSpMiddle"><em>The one of most problem places is ineffective management of queues in network devices that results in worsening the servicing quality. They are based mainly on decentralized algorithms of managing resources, realized on separate nodes of networks. The other important disadvantage is realization of the static hand strategy of allocation of channel resources, which managing process is not always adequate to the profile of input traffic. At the same time solutions, received on separate network nodes in concrete time moments, are not coordinated in the process.</em></p><p class="20CxSpMiddle"><em>For eliminating the aforesaid shortcomings, there is offered to use the improved method of servicing queues in network devices, one of key differences of the offered method is in the control over the time packets’ being in queues. And under conditions of exceeding the permissible time of waiting, a packet is transmitted on a queue with a lower priority and first-turn servicing. It gives a possibility to improve the effectiveness of allocation of network resources by the criterion of servicing quality.</em></p><p class="20CxSpLast"><em>For realizing this approach, there was developed the software-based router model that, as opposite to known ones, has a module structure and gives a possibility to reproduce the work of a telecommunication network of any configuration in the real-time mode. It is provided to use the router prototype for adaptive servicing the load of the main level. Comparing to analogous systems, created, based on CISCO equipment, the aforesaid model provides competitive advantages at the guaranteed quality of servicing the determined real-time streams with the synchronous decrease of cost and complication of their setting. Under conditions of the additional productivity of hardware of the router prototype, the offered model is realized by the developed software. It provides an advantage by the efficiency of delivering correspondent real-time stream, namely decrease of delays at their processing reaches 40 %, jitter decrease – 35 %.</em></p>
