Abstract
Need of global networking is increasing day by day and is a primary need. There has been a rapid growth of the routing protocols in the area of communication. A routing protocol is a protocol which is responsible to determine how routers communicate with each other and forward the packets through optimal path to travel from source node to destination node. The performance of each routing protocol is different from each other. In the context of routing protocol, protocol performance, each of them has different architecture, adaptability, route processing delays, convergence capabilities and many more. Among different routing protocols, Multi Protocol Label Switching (MPLS) has been considered for the IPv4 network. When we want to design a Wide Area Network (WAN), Open Shortest path First (OSPF) is a standard protocol which is being widely used. OSPF is classified as an Interior Gateway Protocol (IGP) which provides fast convergence in larger network. It can be ensure that the latency can be reduced and convergence speed can be made still faster when MPLS protocol is used. MPLS is an innovative approach in which forwarding decision is taken based on labels. It also provides a flexible and graceful VPN solution based on the use of LSP tunnels to encapsulate VPN data. Multi-protocol Layer Switching (MPLS) VPNs are best solution for medium and large enterprises that currently deploy site-to-site VPN services. MPLS provides sophisticated traffic engineering capabilities that, coupled with IP QoS, enable multiple classes of service so business critical applications are treated with higher priority than less important applications and "best effort" services. This project is based on simulation for performance analysis of OSPF protocol and MPLS protocol in IPv4 network by the parameters like Latency and Throughput. The simulation tool used is Graphic Network Simulator (GNS-3) and Wireshark.
