Abstract
A multimode queuing system for DiffServ routers is provided. The multimode buffering and scheduling system that can be adjusted to show either 'pure' AF/EF behavior, 'pure' DSUI behavior, or a combination of the AF/EF behavior and the DSUI behavior. An operation point parameter may be set to select the desired behavior. DiffServ products utilizing the combination of the behaviors are flexible and more configurable as compared to only AF/EF products. The multimode queuing system deployment is simple and is a low cost modification to DiffServ routers. The same hardware and/or software implementation can support both mechanisms with very small additional cost and effort. Also the management of the system is simplified. For example, there is no need for several parallel queuing systems.
