Abstract
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.
