Abstract
A method for path computation in a network includes determining dynamic link weights for links in the network, responsive to a request for a path, for a connection, between a source node and a destination node in the network with a requested bandwidth amount, wherein the dynamic link weights, for each link, are based on a current status of the link and a future status of the link; determining one or more paths for the request based on the dynamic link weights; and selecting a path of the one or more paths to minimize cost in the network. The method can be implemented through a Software Defined Networking (SDN) controller.
