Technologies are developing on a daily basis; thus it is also important to upgrade the communication networks based on those new technologies to be responsive to today`s user requirements. One of these requirements, and a hot topic is Voice over Internet Protocol (VoIP), which is an essential and sensitive application that cannot tolerate too much delay, jitter, packet losses, etc. but which, at the same time, requires high throughput. So, to deal with such kind of problems, a form of service guarantee is needed, namely Quality of Services (QoS). In this thesis we focus on Multiprotocol Label Switching (MPLS) as a mechanism used for supporting QoS in networks for real time traffic VoIP. MPLS can provide enhanced QoS as compared to traditional IP.By using Virtual Private Network (VPN) and Traffic Engineering (TE), MPLS enables the network to provide QoS and to minimize the factors previously mentioned which have affects VoIP traffic. In this thesis, we first focus on theoretical aspects of MPLS, then we analyze its performance and affects compared with traditional IP while transmitting VoIP by using OPNET network simulation.
