The current data network scenario makes Traffic Engineering (TE) a very challenging task. The ever-growing access rates and new applications running on end-hosts result in more variable and un-predictable traffic patterns. By providing Origin-Destination (OD) pairs with several possible paths, load-balancing has proven itself an excellent tool to face this uncertainty. Most previous proposals defined the load-balancing problem as minimizing a certain network cost function of the link's usage, assuming users would obtain a good performance as a consequence. Since the network operator is interested in the communication between the OD nodes, the authors propose instead to state the load-balancing problem in their terms.
