Benefits of technology

[0013]According to the method disclosed herein, the present invention allows ATM traffic to be efficiently managed.

Problems solved by technology

However, ATM does not otherwise specify how traffic is controlled to meet the goals for each the above categories of service.
Furthermore, the conventional ATM scheduler 40 does not in itself provide for a mechanism to discard excess traffic.
However, if such a threshold has a relatively low value, then bursts of traffic may be unnecessarily discarded; if a threshold has relatively high value, then during an episode of steady congestion, all surviving packets may have undesirably high queueing latency.
Therefore setting discard thresholds may present the administrator with burdensome and confusing performance requirements.
Consequently, providing different levels of ATM services in a conventional manner may be relatively difficult and inefficient.

Abstract

A medium 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 medium 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.
