1. A bandwidth management method performed in a Software Defined Networking (SDN) controlled network, the bandwidth management method comprising:
responsive to detecting congestion on a network service with identifiable data therein, obtaining policy associated with the congested network service and causing bandwidth on demand in the network to mitigate the congestion when the bandwidth on demand is possible in the network and permitted based on the policy of the congested network service;
responsive to the congestion remaining subsequent to the bandwidth on demand or when the bandwidth on demand is not possible or permitted, orchestrating bandwidth for the congested network service based on the associated priority in the policy; and
responsive to the congestion remaining subsequent to the orchestrating bandwidth based on priority, orchestrating bandwidth for the congested network service based on an amount remaining to download for the network service and one or more additional network services.
