Abstract
Methods and systems for managing a network. A TSDN controller determines a change or an anticipated change in traffic in the network. The controller identifies one or more congested links in the network by solving an optimization problem for maximizing network utility to accommodate the change or anticipated change. Solving the optimization problem includes solving for a set of link constraint dual variables associated with links of the network. The link capacity of one or more links of the network is adjusted to decrease the congestion.
