Analysis of Quality of Service in Integrated IP Networks (Integrated and Differentiated Services)

The analyses presented show that in modern computer networks, the protocols RSVP, RTP, RTCP, and MPLS ensure reliable and transparent packet transfer and maintain the required quality of service. Comparison of IP technology shows that the best result can be achieved by jointly utilizing the advantages of these technologies. Based on the analysis of integrated and differentiated services in combined ATM and IP networks, it has been shown that the use of these services enables the reservation of resources in computer networks to provide the desired level of quality of service. In a conventional or integrated network, elastic and inelastic traffic can be used.
