Title: FABRIC-WIDE BANDWIDTH MANAGEMENT
Abstract:
In one embodiment, a method includes measuring a rate of traffic received at a leaf node, marking a plurality of packets in the flow as protected at the leaf node to match the rate of traffic with a configured rate of traffic for the flow at the leaf node, and dropping a plurality of non-protected packets at the leaf node when a queue at the leaf node is congested. A minimum bandwidth is provided for the flow based on the configured rate of traffic at the leaf node. The leaf node comprises an ingress node or an egress node connected to a fabric. An apparatus is also disclosed herein.
