Content of Rate Limit Calcuated in CAR

Hi,

Just would like to ask if the average rate and the burst size in the CAR configuration include the medium overhead. Say, if I want to do CAR in an ATM interface to 10Mb/s, do I need to count in the 15-20% overhead imposed by ATM or CAR ?

Best Regards

Raymond Lo

Hi,

You need to encorporate the overhead also while calculating the average rate and the burst size in the CAR configuration.

For any QOS , we need to consider all types of overhead that can occur.

See the following document:
