I would like to use drop precedence of the EF classe in order to prioritize some phone call in case of congestion.
So, voip flux with higher drop precedence would be discarded before voip flux with lower drop precedence.
I wanted to use LLQ algorithm to give maximum priority to EF class and use RED algorithm to delete packet according to their drop precedence value. But according to what I could read on cisco documentation, RED can't be use with LLQ algorithm (logic as voip don't use TCP windows).
Which technik of packet discarding could I use with LLQ algorithm to be able to discard packet in accordance with their drop precedence?
Thanks for your help.
