Frame Relay Overview

Setting Minimum Acceptable Throughput

Throughput that an SVC actually uses may be less than it requests because the

local router, the frame relay network, and the remote end of the connection

negotiate QoS. You can use the Outgoing and Incoming Minimum Acceptable

Throughput attributes or parameters to set the lowest throughput value the router

will accept. If either the local router, the network, or the remote end cannot

guarantee that value, the SVC will not be established.

Defining

Incoming

and

Outgoing

If a local router originates the call, the outgoing committed burst, excess burst,

and throughput values define characteristics of data the local router transmits,

while the incoming values define characteristics of data the local router receives.

If the local router receives a call, the outgoing values define characteristics of data

the local router receives, while incoming values define characteristics of data the

local router transmits. Table 2-6

explains this further.

Traffic Shaping Considerations

Traffic shaping is best used at central offices to prevent the “big pipe” from

sending too much data too quickly to remote sites with “little pipes.” Let this

principle guide your decisions about how to use traffic shaping on your network.
