Abstract

A method and a system for controlling data flow through a network device involve regulating a first flow of network traffic with a first traffic control rule, regulating a second flow of network traffic with a second traffic control rule, and then regulating the passed portion of the two flows with a third traffic control rule that is generic to both the first flow and the second flow. The third traffic control rule regulates the passed portions of the first flow and the second flow on an aggregate basis, such that the total amount of traffic passed by the third traffic control rule does not exceed a predefined bandwidth limit. By regulating the bandwidth consumption of a group of flows with at least two levels of traffic control rules, bandwidth consumption can be simultaneously controlled for narrowly defined flows and more broadly defined flows.
