Abstract
The aim of this work is to study and analyze the security of MPLS (Multi-Protocol Label
Switching) technology. Also, the study of a case of telephony implementation over the
MPLS VPN network will be presented and the security provided by this solution will be
analyzed. The work consists of the following sections. The first chapter analyzes MPLS
technology, and specifically the way of operation and architecture of MPLS and the
presentation of its features - advantages. The second chapter describes the potential threats
that an MPLS network may face by endangering both the network itself and all the services
it supports. The third chapter will analyze the security provided by an MPLS network,
while the fourth chapter will mention some suggestions for its strengthening. The fifth
chapter analyzes IP sec. Finally, the sixth chapter will present a practical implementation
of an MPLS VPN on which internal telephony has been implemented which is routed over
the closed MPLS circuit safely
