It's my turn to disagree :). If we are going to consider quality of service from ISP point of view then don't you think that rate-limit is giving you the advantage of passing exceding traffic for your client after marking it such that if you do have free bandwidth as the ISP you can let this traffic through, and drop it if not? Using rate-limit in such a way means that you can think of charging your client more for giving him such an option.
This is not acheivable using traffic-shapping as it just sets a threshold and drops packets exceeding that threshold. What you are doing means to me that you find traffic-shapping is better than rate-limitting so you are applying it on the outgoing traffic to the client. However, as it is unidirectional and you can't rely on asking the client to do it from his side also for the other direction so the only alternative is to rate-limit on the incoming traffic. Would you kindly explain to us why you find your way would provide a better quality from the ISP ? Regards, Yasser >From: Jay Greenberg > >I would have to disagree.
