Traditionally, IP (Internet Protocol) has been routed over ATM (Asynchronous Transfer Mode) via Virtual Circuits (VCs) or Multi-Protocol over ATM (MPOA). These methods proved to have a complicated operation mode, reason why the necessity for a simpler method was felt. All these necessities can be supported by the Multi-Protocol Label Switching (MPLS) since it integrates the most important characteristics of layers 2 and 3 of the OSI model. This paper explains and analyzes the concepts of MPLS, as well as performing a simulation and comparison of path restoration schemes using Network Simulator (NS). The results show the advantages of working over a connection-oriented technology (MPLS) by supporting a more efficient rerouting scheme for link failures.
