Using Traffic Shaping with SVCs

To use traffic shaping, you set attributes or parameters specific to throughput,

committed burst, and excess burst. To enhance the effectiveness of traffic shaping,

you may also want to edit values for the SVC Congestion Control and Congestion

Method attributes or parameters. For more information about the interaction

between these elements and traffic shaping, see “Traffic Shaping Considerations”

in Chapter 2.

You can use either the BCC or Site Manager to shape traffic with SVCs.

Using the BCC

To configure traffic shaping you set values for committed burst, excess-burst, CIR,

and traffic shaping.

Committed Burst

The committed burst rate (B

) defines the number of bits the router can transmit

over a specified time interval when congestion occurs. For SVCs you configure

two attributes to define committed burst: committed-burst-in and

committed-burst-out. These are, respectively the maximum number of bits that a

VC can receive and transmit during the VC’s burst period when congestion is

occurring. To enable traffic shaping, these attributes and the CIR attributes must

be greater than zero. The values in the committed burst attributes should be lower

than the CIR attributes.

To change the value for committed-burst-in or committed-burst-out:

Navigate to the prompt for the SVC that you want to edit.

For example:

serial/1/2; frame-relay/1/2; service/8.0.32; svc-options/toronto

Enter the

committed-burst-in

command and the integer value you want

the PVC to use:

committed-burst-in

committed-burst-out

is the number of bits the router can transmit per time interval.

Legal values are 0 to 2,147,483,647 bits. The default is 0.
