Traffic engineering deals with the optimization of work in already installed networks combining different knowledge of the theory of traffic. The aim is to optimally utilize network resources and to improve the quality of services offered. Traffic engineering can be oriented to improve traffic flows and service parameters or to improve utilization of network resources. One of the functions of the label is to provide a mechanism that integrates with the packet in the routing process, and in this way provide "guidance" of packet at a predetermined paths through the network. With further administrative manipulations it is possible to provide manual load distribution in the network and thus the maximum utilization of the available bandwidth in the network (it is possible that some, most attractive parts of the network carry the maximum load, while other parts remain unused).
