This paper comes with a solution to the use of multiple simultaneous applications (data and voice) in a secure trouble-free environment. More exactly, it presents a network based not only on hybrid MPLS-VPN (Multiprotocol Label Switching - Virtul Private Network), but also on Quality of Service and Traffic Engineering. The main purpose of this work is to assure no congestion or delays on the routes of the customers and to make space for the allocation of resources for different communication sessions.
