The analytical modl of IP/MPLS network

In this paper, the analysis of multi-servicing IP network with Multi-Protocol Label Switching (MPLS) protocol based on the proposed analytical and simulation models has been carried out. In the models two classes of service with different QoS parameters have been analyzed: class High, responsible for example for the Premium service, and class Low services for transmission of data. In this paper the changes of packet delays and lengths of queues for the given class of services in the network were taken into account, depending on the changes of average packet lengths, load of the network and the amount of inelastic traffic in the whole traffic. The results obtained in this paper have proved, that proposed analytical model is useful for analysis of the IP networks with MPLS protocol.
