TECHNIQUES FOR END-TO-END NETWORK BANDWIDTH OPTIMIZATION USING SOFTWARE DEFINED NETWORKING

摘要

Techniques for end-to-end network bandwidth optimization using software defined networking are provided. In one embodiment, a computer system can receive information regarding a flow to be admitted to a network, where the flow is associated with a source and a destination. The computer system can further calculate, for each path in a plurality of paths between the source and the destination, a projected utilization of the path in view of the flow. If the projected utilization of the shortest path in the plurality of paths is less than or equal to a target utilization threshold, the computer system can assign the flow to the shortest path. Otherwise, the computer system can select a path in the plurality of paths that comes closest to the target utilization threshold without exceeding the threshold and can assign the flow to that selected path.

1. A method comprising:
receiving, by a computer system, information regarding a flow to be admitted to a network, the flow being associated with a source and a destination; for each path in a plurality of paths between the source and the destination, calculating, by the computer system, a projected utilization of the path in view of the flow; if the projected utilization of a shortest path in the plurality of paths is less than or equal to a target utilization threshold, assigning, by the computer system, the flow to the shortest path; else if the projected utilization of the shortest path is greater than the target utilization threshold:
selecting, by the computer system, a path in the plurality of paths whose projected utilization comes closest to the target utilization threshold without exceeding the threshold; andassigning, by the computer system, the flow to the selected path.
