MPLS IMPLEMETATION ON LAYER 3 PROTOCOLS

Abstract

This paper presents an overview of the basic operations that characterize MPLS technology and the distribution of its applications. The paper is structured in 4 chapters. It begins with a superficial description of the "MPLS world", the historical reasons for the need for this technology and its advantages as a technique that combines the labeled transfer qualities prevalent in Frame Relay and ATM technologies with the ease of distribution IP networks. Next is an overview of the MPLS tag architecture, how to transfer them to the MPLS network and some of the working methods in this network. Given that the field of MPLS technology applications is very wide and would require much longer work, only two of its applications have been studied in more detail: ATM as one of the earliest applications and MPLS VPN as its most widespread and popular application. Finally, the implementation of this technology in the network of the company ALBTELECOM is presented in detail. The new method of packet transfer offered by MPLS technology led to the successful invention of many new applications that realize the transmission of packets based on tags such as: MPLS VPN, Traffic Engineering, AToM and VPLS. In this context, since MPLS is a mature technology, it is expected that in the future it will have further developments just as successful as those of the present. The purpose of this paper is to provide the most understandable and practical information about MPLS technology and its applications, laying the foundations for the formation of a network engineering in the field of MPLS networks. The methodology used is that of theoretical-practical treatment where the theoretical part is accompanied by practical examples, configuration schemes, details on how to implement and solve the problems of MPLS and its applications. This methodology makes it easy to understand what the paper deals with and at the same time makes it faster and easier to be assimilated by the reader.
