Simulation Based Analysis of Voice over Multi Protocol Label Switching Networks 1ABSTRACT Problem Statement: The main aim of this thesis work is to investigate the performance of realtime voice traffic in IP networks and MPLS networks by including Traffic Engineering in MPLS. a. Studying the stateofart of MPLS architecture and IP networks through literature study. b. Investigating the problems related when routing the realtime voice communications over IP networks through literature study 2c. Choosing the performance parameters such as EndtoEnd delay, throughput, voice jitter, packets sent and packets received. d. Designing two network models for IP and MPLS considering same network topology and analyzing the results by considering the same performance parameters. 3E. Studying the performance of realtime voice communications in MPLS network when TE is considered. 4What is MPLS • It is an Internet Engineering Task Force that specified frameworks which provides for the efficient routing, forwarding and switching of traffic flows through the network. • It is considered to be the most perfect solution to address the most recently faced problems in presentday networks such as“Routing, scalability, quality of service engineering management, trafficengineering”.What is MPLS Multi Protocol – supports protocols even other than IP  Supports IPv4, IPv6, IPX, AppleTalk at the network layer  Supports Ethernet, Token Ring, FDDI, ATM, Frame Relay, PPP at the link layer Label– short fixed length identifier to determine a route  Labels are added to the top of the IP packet  Labels are assigned when the packet enters the MPLS domainSwitching – Forwarding a packet Packets are forwarded based on the label value NOT on the basis of IP header information 7Software and hardware Requirement Software Requirements 1.OPNET 16.0 Modeller (Paid Tool) 2.VANET MobiSim 3.Visual Studio 10.0 Hardware Requirements 1.
