Evaluation Of MPLS In IMS Network With Considering TE

An architecture known as the promising solution for the next generation multimedia communication is the IP Multimedia Subsystem (IMS). Internet technologies can be widely available on Earth thanks to a support of the IMS. To be more exact, people can find them almost anywhere, anytime and on any device such as email, web, instant messaging, presence, videoconferencing, may be even on mobility devices. Higher and higher requirement of using multimedia services demands mechanisms which can manage high performance mobility. Mobile IP (MIP) and Session Initiation Protocol (SIP), which could be the most suitable protocols, are integrated in IMS architecture to satisfy the demands above.However, there are still further demands related to quality of traffic treatment and effective network resource utilization due to a fast development of the Internet network. In order to deal with these challenges, analyzing Traffic Engineering (TE) has been shown as a key feature to controlling and measuring traffic in the messing network. Regarding to this aspect, Multi-Protocol Label Switching (MPLS) technology emerged as a good solution. The most evident advantages of the MPLS are supported by a separation between controlling planes and forwarding planes. Consequently, scalability and flexibility could be enhanced.Therefore, this study focuses on discovering potential ability of the MPLS-TE basing on the integrated MIP and SIP IMS achitecture. It also exposes MPLS means of implementing TE and methods to provide its resiliency. Moreover, MPLS internal operation, its signalling protocols, and network resiliency concerns are mentioned as the research's broad context. To conduct the study, OPNET Modeller tool is used to simulate the MPLS-TE features within the network model.
