Abstract
A method includes provisioning joint bandwidth in a software defined passive optical network PON based mobile backhaul MBH and cache management on base stations for video delivery across the network, the provisioning in each time unit includes grouping bandwidth utilization in the network into a first category used to support video requests which cannot directly be served by caches on base stations, the first category video requests being high priority, and if bandwidth remains after the high priority requests remaining bandwidth being used to deliver some videos that are low priority to caches.
