چکیده

Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order to provide the quality of service to stream multimedia. The performance of the EMPLS-TE is evaluated by a simulation model under a variety of network conditions. We also compare its performance with that of unmodified MPLS-TE and MPLS. We demonstrate how a small change to the MPLSTE protocol can lead to significantly improved performance results. We present a comparative analysis between MPLS, MPLS-TE and Enhanced MPLS-TE (EMPLS-TE). Our proposed EMPLS-TE has a performance advantageous for multimedia applications in their movement in a congested and dense environment. EMPLS-TE defines paths for network traffic based on certain quality of service. The simulation study is conducted in this paper; it is a means to illustrate the benefits of using this Enhanced MPLS-TE for multimedia applications. KeywordsMulti-Protocol Label Switching (MPLS); Multi-Protocol Label Switching Traffic Engineering (MPLS-TE); Forwarding Equivalence Class (FEC); Quality Of Service (QoS); Simulation.

Prioritized OSPF-TE Mechanism for Multimedia Applications in MPLS Networks

Real time multimedia applications such as video streaming have been greatly introduced in networks and require Quality of Service (QoS). In MPLS based networks, OSPF with traffic engineering is widely used. It is responsible for finding feasible routes within networks, which have link state constraints such as bandwidth or delay. To serve dynamically changed traffic characteristics, OSPFTE need...

On the Performance of MPLS TE Queues for QoS Routing

Traffic engineering (TE) refers to techniques and processes to route traffic through a network on a path other than that would have been chosen if standard routing methods had been used. The goal of traffic engineering to a service provider is to maximize the utilization of network resources, and/or enhance QoS a service provider can offer. To justify the increase in network operational complex...
