SCHEDULING FRAMEWORK FOR ADAPTIVE VIDEO DELIVERY OVER CELLULAR NETWORKS

摘要

Systems and methods for adaptive video delivery over a network, including receiving a plurality of types of data flows from one or more network base stations; separating resource management of the plurality of types of data flows, wherein the data flows include one or more of adaptive video streaming flows, regular video traffic flows, and other traffic flows by resource slicing. A scheduling framework for adaptive video delivery is instantiated; available choices of video bit rates for all users is received as input to an allocator; optimal allocation of resources is computed for all users by determining and selecting an optimal bit rate for each user using the allocator; the optimal bit rate being sent to an enforcer; resources across flows are isolated using the enforcer; and the optimal bit rate for each user is enforced using per-flow traffic shapers to maximize resource utilization without reaching network capacity.

1. A method for adaptive video delivery over a network, comprising:
receiving a plurality of types of data flows from one or more network base stations; separating resource management of the plurality of types of data flows, wherein the plurality of types of data flows include one or more of adaptive video streaming flows, regular video traffic flows, and other traffic flows by resource slicing; instantiating a scheduling framework for adaptive video delivery; receiving available choices of video bit rates for all users as input to an allocator; computing optimal allocation of resources for all users by determining and selecting an optimal bit rate for each user using the allocator; sending the optimal bit rate for each user to an enforcer; isolating resources across the adaptive video streaming flows using the enforcer; and enforcing the optimal bit rate for each user using one or more per-flow traffic shapers to maximize resource utilization without reaching network capacity.
