Abstract

Multiprotocol Label Switching (MPLS) is an evolving standards-approved technology to increase the speed of the network traffic flow and making the network easier to manage. In MPLS a specific path is set up for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet. MPLS is called multiprotocol because it works with the Internet Protocol (IP),Asynchronous Transport Mode(ATM), frame relay network protocols. It ensures the efficient and reliable delivery of the Internet services with high transmission speed and lower delays. The main feature of MPLS is the concept of Traffic Engineering (TE), which is used for effectively managing the networks for efficient utilization of network resources. This technology is more suitable for implementing real-time applications such as voice and video due to lower network delay, efficient forwarding mechanism, scalability and predictable performance of the services provided by MPLS. In this paper the performance of voice over internet protocol in MPLS and non MPLS network is compared. Here we consider non-MPLS network as conventional IP network. In order to simulate the network we use Optimized Network Engineering Tool 14.5 and comparison is made on various parameters such as Ethernet delay, voice jitter, voice packet end to end delay.
