The traffic engineering seeks to ensure that the network operations are efficient and reliable, but, at the same time, that the use of network resources and the performance are optimal. Applying traffic engineering to a communication network implies to design in which way the traffic flows will travel through the network, trying to make it more efficient. The routing has the function to interconnect all the devices logically, and the network engineering models the way in which such flow will cross the central network. In a basic and limited way, it is possible to apply traffic engineering in the routing, but it is convenient to have a more evolved protocol, which offers more benefits and granularity in the decisions (the new protocol should not have the limitations of older traffic engineering techniques). The MPLS protocol is the protocol which was created and which is used and it has these functions.
The IP/MPLS techniques, among the many advantages, allow to make routing decisions, being based on several parameters, and they allow to differentiate the many traffic flows, making particular decisions as regards the routing of each flow. MPLS works independently to the normal routing tables, which still exist and play their role of interconnection. The routing sets the basis on which MPLS works.
In Auben, we specialize in the implementation and design of IP/MPLS networks and we have great experience leading the developments in the region successfully. We apply all our knowledge, intending to build the networks which allow providers and operators to offer the best possible service.
