Traffic prioritization in MPLS enabled OSPF network

Abstract

This paper presents treatment of incoming traffic in Multi-Protocol Label Switching (MPLS) enabled Open Shortest Path First (OSPF) network where traffic is classified based on its type. In this paper, the network is simulated with incoming traffic as a mixture of delay sensitive voice and web browsing data. End-to-end Quality of Service (QoS) is ensured using Forward Equivalence Class (FEC) and thus voice packets are given primary importance. Comparison is drawn between the OSPF network and MPLS enabled OSPF network to show the low voice delays and increase in number of http object responses in MPLS core.
