The impact of increased video traffic on quality of service parameters in next generation IP/MPLS network

Insufficient quality of service (QoS) of the emerging multimedia applications is a growing concern that has led the need for research and study. In this paper we investigate the impact of increased video traffic on QoS parameters and their correlation in next generation network. Multi-protocol label switching (MPLS) and differentiated services (DiffServ) integration is very useful strategy for today´s traffic. MPLS Traffic Engineering (TE) plays an important role in the implementation of network services with QoS guarantees. The aim of simulation study is to underline how MPLS TE and MPLS Diffserv integration improve the performances of today´s networks, and identify opportunities for improvement, and development of new mechanisms to ensure QoS features in future networks.
