Implementation of Multi Protocol Label Switching

• MPLS(Multi Protocol label Switching) is a switching technique where the forwarding decision is done on the basis of a specially added label in the IP-header, in order to increase the efficiency of forwarding by avoiding unnecessary analysis of the network layer header at each router.This project is a working implementation of the basic features of the MPLS architecture.The Goal of the project is to obtain an understanding of the working of the technology by implementing  some of its basic features.

The project has the following salient features:

• Ability to capture and label IP packets once they enter an MPLS domain.

• Ability to forward labeled packets independently of network layer involvement within the MPLS domain.

• Ability to perform some basic operations on the header of a labeled packet at each LSR(Label Switched Router) when necessary.

• Ability to tunnel packets through other LSPs(Label Switching Paths) or through an IP domain.

• Creation and maintenance of the data structures prescribed in the standards document.
