• You can set the SVC Traffic Shaping Disable attribute or parameter to Enable,

and provide values for the LL Core traffic shaping attribute or parameters.

If you supply values for the LL Core attribute or parameters, the router

requests an SVC from the frame relay network with the quality of service you

have designed. However, the router can only request the values you have

configured. The actual values the network supplies may be less than requested

because the local router, the network, and the remote end negotiate the actual

quality of service. To track the values an SVC uses, use the Site Manager

Statistics Manager (for more information, see Configuring and Managing

Routers with Site Manager).

• You can set the SVC Traffic Shaping Disable attribute or parameter to

Disable, and provide values for the LL Core Committed Burst, Excess Burst

and Throughput attribute or parameters.

If you configure traffic shaping this way, the router does not enforce the CIR it

requests from the frame relay network. There is a risk of oversubscribing the

interface, which may result in dropped packets.

Refining Quality of Service for SVCs

SVCs allow you to refine quality of service requirements in that you can specify

values for traffic shaping attribute or parameters for both incoming and outgoing

directions, and you can set values for incoming and outgoing minimum acceptable

throughput.

The values you set in incoming and outgoing attribute or parameters apply to

traffic depending on where the SVC call originates. See “Defining

Incoming and

Outgoing” on page 2-29 to understand how the software uses these attribute or

parameters.

Refining Traffic Shaping

The attribute or parameters involved are the LL Core Out Throughput (CIR), LL

Core Out Committed Burst, LL Core Out Excess Burst, LL Core In Throughput

(CIR), LL Core In Committed Burst, and LL Core In Excess Burst. You can use

these attribute or parameters to request values for traffic shaping that distinguish

between incoming and outgoing traffic.
