QoS of communication networks using MPLS protocol
This chapter describes the place of multiprotocol label switching (MPLS) in current state-of-the-art computer networking systems which emphasize the use of MPLS as a quality of service (QoS) technique in different networking environments such as data centers and multimedia networking as backbone networks. The chapter also includes practical experiments, which are applied using the OPNET network simulation tool for transmitting multimedia over IP/MPLS networks and a fat tree data center architecture employing MPLS. The examples show the feasibility of MPLS as a QoS tool compared to best-effort IP networks. In addition, this chapter describes an effort of designing a network-on-chip system engaging MPLS mechanism as on-chip communication method which has been completely developed in Cþþ. However, all results clearly confirm that MPLS is an efficient QoS tool.
