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.
