SYSTEM AND METHOD TO CONTROL BANDWIDTH OF CLASSES OF NETWORK TRAFFIC USING BANDWIDTH LIMITS AND RESERVATIONS

摘要

In various example embodiments, a system and method are presented for a bandwidth (BW) management system. The BW management system includes a BW manager module to manage bandwidth of a collection of flows by traffic classes using bandwidth limits assigned to the traffic classes arranged in a hierarchical bandwidth tree (HBT). The BW management system includes a quality of service (QOS) manager module to manage bandwidth for leaf traffic subclasses in the HBT based on application priority classifications. The bandwidth management system including a window manager (WM) module to manage bandwidth for individual flows in the collection of flows using a sliding window protocol to control the rate at which the first host transmits data packets to the second host. The QOS manager module is in communication with the WM module and the BW manager module while the bandwidth management system is actively managing the bandwidth of the collection of flows.

1. A system for bandwidth management, comprising:
at least one processor configured to perform operations for processor-implemented modules including: a bandwidth (BW) manager module configured to manage bandwidth of a collection of flows by traffic classes using bandwidth limits assigned to the traffic classes, the traffic classes arranged in a hierarchical bandwidth tree (HBT), a traffic class at the highest level of the HBT represents a universal traffic class, the traffic classes at the lowest level of the HBT represent leaf traffic subclasses, each of the flows representing an end-to-end connection between two hosts; a quality of service (QOS) manager module configured to manage the bandwidth for the leaf traffic subclasses based on application priority classifications of the flows associated with the leaf traffic subclasses; a window manager (WM) module configured to manage bandwidth for individual flows in the collection of flows using a sliding window protocol to control the rate at which a first host transmits data packets to a second host; and wherein the QOS manager module is in communication with the WM module and the BW manager module while the bandwidth management system is actively managing the bandwidth of the collection of flows.
