Class-Based Traffic Shaping - CBWFQ

Class-Based Shaping (Cisco Systems)
Traffic shaping allows you to control the traffic going out an interface in order to match its transmission to the speed of the remote, target interface and to ensure that the traffic conforms to policies contracted for it. Traffic adhering to a particular profile can be shaped to meet downstream requirements, thereby eliminating bottlenecks in topologies with data-rate mismatches.

Using the Class-Based Shaping feature, you can do the following:
Configure generic traffic shaping (GTS) on a traffic class
Specify average rate or peak rate traffic shaping
Configure class-based weighted fair queueing (CBWFQ) inside GTS

Class-based shaping can be enabled on any interface that supports GTS.
