1. A method for Quality of Experience (QoE) management on a network, the method comprising:
determining a set of service categories for a network operator's traffic, wherein at least one of the service categories is video streaming;
mapping a plurality of traffic flows to each of the service categories;
determining a target and minimum bandwidth intent for each of the service categories for the network operator;
measuring a score, based at least in part on the Quality of Experience of a set of users, wherein the set of users comprises a subset of total users of the network, and bandwidth use for each of the service categories;
determining whether each of the service categories are reaching an associated minimum bandwidth intent;
if the minimum bandwidth intent is not being reached for at least one service category, reducing the minimum bandwidth intent for the video streaming service categories;
allocating a bandwidth per service category based on the reduced minimum bandwidth intent; and
shaping the traffic flow to the allocated bandwidth;
otherwise allowing the traffic flow to continue with a current bandwidth allocation.
