The appearance of new use underlines the need for a greater quality of service (QoS) not only for conveying accurately or increasing a certain traffic, but also conveying it as soon as possible while holding management account of the resources networks (bandwidth, availability and reliability), which implies a network management even more complex. These are the needs which gave birth to MPLS (Multi Protocol Switching Label) technology. The Mechanisms of engineering of traffic, QoS and security become necessary to support "triple play" (Internet, voice/videoconference, television IPTV, video on demand VoD), in terms of volume, nature of the transported traffics. Various methods of traffic engineering for IP networks have been specified for many years ago. MPLS technology is one among these methods. This technology is particularly well adapted to traffic engineering since it allows the creation of ways that are explicit and independent from IP itinerary. In this article we tried to reduce principal operations from MPLS protocol in IP Multimedia Subsystem (IMS) architecture. We propose to associate the QoS management mechanisms in the Next Generation Networks (NGN) architecture especially with transport IMS layer. We will strongly highlight the importance of the MPLS used for the transport of the IP datagram and the traffic. We underline the advantages of MPLS utility in the IMS platforms to provide E2E guarantees QoS. We conclude our article by a simulation from an MPLS network. © 2010 Praise Worthy Prize S.r.l. Source
