Analysis of Voice, Video & Data Services in a Telecommunication Service Provider Core Network

Abstract

To provide Voice and Video services over Internet Protocol (IP) has provoked the network service providers to adopt and develop such a network technology which provides manageability comes with efficiency. Multi Protocol Label Switching (MPLS) is an evolving network technology which provides speed, efficiency and manageability. Transferring voice and video have been there before MPLS, Asynchronous Transfer Mode (ATM) was providing voice and video services requires separate ATM network to manage and operate. As MPLS is there so transferring the voice and video over IP over MPLS is the hot topic among the service providers. The thesis provides traffic analysis of voice, video and data services on IP, MPLS-LDP and MPLS-RSVP based networks. The thesis assists the service provider industry in the understanding of a MPLS network working and the benefits of using MPLS-RSVP in their core networks. The thesis includes implementation of a service provider core network in a lab and analysis of packet per second and bits per second of FTP (file transfer protocol) and video conferencing traffic on each OSPF, MPLS-LDP and MPLS-RSVP. The results showed that by implementing MPLS-RSVP a network service provider can decrease the running time of routing lookup decisions and enhance the overall efficiency of the network even better than MPLS-LDP. MPLS-RSVP has not been adopted by service providers due to its unreliability that is why it is also suggested to use MPLS-RSVP over MPLS-LDP.
