SYSTEMS AND METHODS FOR PERFORMING TRAFFIC ENGINEERING IN A COMMUNICATIONS NETWORK
First Claim
1. A method for performing traffic engineering for a flow traversing a communications network, the communications network having a plurality of nodes communicatively coupled by a plurality of links, at least one of the plurality of links being a wireless link, the method comprising:
- setting an activation factor for the at least one wireless link, in accordance with buffer statuses associated with nodes traversed by the flow; and
transmitting the activation factor to a scheduling entity for scheduling activation of the at least one wireless link in accordance with the activation factor.
