Mankivskyi V. Evaluation method quality of service and bandwidth abilities in tunnel of MPLS network at service voice load.

The dissertation is devoted to the development of methods for assessing the quality of service and bandwidth of the MPLS network serviced by voice. The mathematical model of functioning of the MPLS network in the mode of voice messages service is developed, this model allows to decompose the network into separate directions of communication, put the corresponding LSP of the MPLS network in line with the direction, bring the model to the standard SMO . The method of calculating MPLS network bandwidth differs from existing ones is improved by introducing the stage of forecasting the likelihood of losses on the tunnels of the network to the load distribution stage. The method of calculating the required productivity of MPLS network branches on the parameters of bandwidth is improved. Reduced computational complexity with unambiguous determination of the order of choice for calculating the directions of communication, as well as increased accuracy of the results.
