Traffic engineering plays a critical role in determining the performance and reliability of a network. A major challenge in traffic engineering is how to cope with dynamic and unpredictable changes in traffic demand. In this paper, the authors provide a survey of traffic engineering approaches that are aware of routing information gathered from past scenarios and they come up with a history aware traffic engineering model. Despite the fact that the connection-oriented approach targets at overcoming the constraints of the connectionless scheme, MPLS has not prevailed yet.
