Explanation:

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.
Configuring GTS on a Traffic Class
Using the Class-Based Shaping feature, you can configure GTS on a class, rather than only on an access control list (ACL). In order to do so, you must first define traffic classes based on match criteria including protocols, ACLs, and input interfaces. You can then apply traffic shaping to each defined class.
Specifying Average Rate or Peak Rate Traffic Shaping
Traffic shaping limits the rate of transmission of data. In addition to using a specifically configured transmission rate, you can use GTS to specify a derived transmission rate based on the level of congestion.
You can specify two types of traffic shaping; average rate shaping and peak rate shaping. Average Domain.com rate shaping limits the transmission rate to the committed information rate (CIR). Using the CIR ensures that the average amount of traffic being sent conforms to the rate expected by the network.
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate, the router uses the following formula:
peak rate = CIR(1+Be/Bc)
where:

Be is the Excess Burst rate.

Bc is the Committed Burst rate.
Peak rate shaping allows the router to burst higher than average rate shaping. However, using peak rate shaping, the traffic sent above the CIR (the delta) has the potential of being dropped if the network becomes congested.
If your network has additional bandwidth available (over the provisioned CIR) and the application or class can tolerate occasional packet loss, that extra bandwidth can be exploited through the use of peak rate shaping. However, there may be occasional packet drops when network congestion occurs. If the traffic being sent to the network must strictly conform to the configured network provisioned CIR, then you should use average traffic shaping.
Configuring CBWFQ Inside GTS
Prior to this release, when GTS queues packets that, when sent, cause the traffic flow to violate the configured rate, only flow-based WFQ was supported for the queued packets. Using the Class-Based Shaping feature, CBWFQ is supported for the queued packets. You can use CBWQ to configure classes of queued traffic and provide relative or absolute bandwidth guarantees to those classes. Note that the relative or absolute bandwidth guarantees are with regard to the configured CIR.
