Abstract
A method and system for managing asynchronous transfer mode (ATM) traffic in a computer system is disclosed. The computer system is used in sending, receiving, or sending and receiving a plurality of ATM flows. Each ATM flow has a plurality of ATM cells, a minimum ATM bandwidth guarantee, and a maximum ATM bandwidth. The method and system include determining whether excess bandwidth exists for the ATM flows. The method and system also include gracefully increasing a portion of the ATM cells transmitted for each ATM flow during periods of excess bandwidth. The portion of the ATM cells transmitted is not more than the maximum ATM bandwidth limit. If an ATM flow presents a sufficient offered load, the portion of the ATM cells transmitted in the flow is not less than a minimum ATM bandwidth guarantee.
