Guaranteeing types of service in a packet-based system

摘要

A traffic management system for addressing quality-of-service concerns in a packet system combines a peak-rate shaper with weighted fair queuing scheduler for providing quality of service guarantees to a number of user connections. In one example, a front-end peak-rate shaper is combined with weighted fair queuing scheduler for providing both peak rate shaping and an average bandwidth guarantee to a number of user connections. In addition, a back-end peak-rate shaper is combined with the weighted fair queuing scheduler for ensuring packets are not transmitted at a data rate higher than the available downlink/uplink bandwidth.
