Configuring Frame Relay Frame Size for Frame Relay to ATM
Interworking
Frame Relay frame size is one of the parameters in IWF equations used for converting Frame Relay
traffic parameters to their equivalent ATM traffic parameters and vice-versa. The default configuration
uses a constant frame size of 250 bytes in the IWF equations. For some Frame Relay network
configurations this could cause problems such as:
•
•
To overcome this problem you can configure the Frame Relay frame size.
If the incoming traffic is always a single frame length, then configure that frame size in the connection
traffic table row (CTTR). However, if the incoming traffic has a varying frame-size, then configure the
Frame Relay CTTR using the highest sustained cell rate (SCR) for a given committed information rate
(CIR) in the corresponding ATM-CTTR. Refer to the section
