simulations of mpls networks using omnet++

In this Master Thesis a detailed presentation and analysis of all aspects of
the Multiprotocol Label Switching (MPLS) technology is provided. After an
introduction in the pre-MPLS technologies and a brief report of its advantages,
the MPLS architecture and basic network elements are being examined. There is a
specific mention on the Label Distribution Protocol (LDP). Subsequently, we
explain the packet forwarding in MPLS networks and the role played by the
labels. Afterwards, particular emphasis is given in the presentation of the two
fundamentals MPLS applications: Virtual Private Network (VPN) and Traffic
Engineering. We also examine two different Quality of Service models for MPLS,
as well as the suggested ways of carrying IPv6 packets across the MPLS
backbone. Finally, we analyze the areas expected to be the main focus of the
efforts regarding the development of MPLS. Finally, for the practical
verification of the knowledge reflected in our analysis, some case studies of
MPLS networks were made using the OMNeT++ simulation tool. Firstly, we study
two existing simulations of the INET framework concerning a) the operation and
forwarding of packets in MPLS networks and b) the function of the LDP for label
distribution. After that, we create and present two new simulations about MPLS
basic applications. The first simulation is about the operation of an MPLS VPN
network and the second one, about the MPLS Traffic Engineering. The code of the
simulations is given in the Annexes I and II.
