Abstract
A method and apparatus for the efficient dynamic allocation of additional bandwidth in an optical virtual private network (OVPN) are described herein. A software defined network (SDN) controller may receive a request from an end-user of an OVPN for active bandwidth. Then, the SDN controller may determine whether the OVPN requires additional bandwidth to satisfy the request. As of the request, the additional bandwidth may be pre-deployed, but not yet activated for use. In an example, a path computation element (PCE) of the SDN controller may make this determination. Further, the SDN controller, on a condition that additional bandwidth is required, may determine whether additional bandwidth may be activated based on a policy of the end-user. As a result, the SDN controller, on a condition that additional bandwidth may be activated, may transmit an activation message to one or more line cards of the OVPN to activate the additional bandwidth.
