QOS policy for http (asymetric trafic)

[vrz rrr]

hello all,

I know that http traffic is asymetric, I mean that outgoing traffic has a smaller volume than incoming trafic. (web browsing, no file transfert from inside)

my question :

does it make sense from a QOS point of view to allocate a smaller bandwidth on the inside interface for outgoing packets and a greater one on the outside interface for the returning traffic ?

Thank you for replying.

Best regards.

V.

"it" = QoS policy

"why" = for the reasons you mentioned in your original post.

I.e. Often QoS policies can customized or unique for traffic that's expected to pass through them.

As another example, if you only use FTP to transfer some data from the Internet but never to it, a "down" policy might have special QoS treatment for the expected FTP traffic; and "up" policy no special treatment, at all, for FTP traffic.

Ok, but I do not understand why you are answering that way, along with that "legal" and awful disclaimer.

Regards anyway.

Laugh - yes the "legal" stuff above is awful!  Alas, it's in response to what's in the Cisco User Agreement to use this site.  I've been in court over contract dispute and the Cisco's user agreement shouldn't be taken too lightly, but I digress.

If my answer still isn't clear or you feel your question isn't answered, let me know.

Your original question was:

my question :

does it make sense from a QOS point of view to  allocate a smaller bandwidth on the inside interface for outgoing  packets and a greater one on the outside interface for the returning  traffic ?

I originally answered "It may/could."  a very brief way of saying yes, it may make sense or it could make sense from a QoS point of view to allocate smaller bandwidth on the inside interface for outgoing  packets and a greater one on the outside interface for the returning  traffic.

The reason for may/could, it might not too.  QoS depends on what you're trying and/or need to accomplish with QoS.  QoS policies in each direction might be identical or very much different.
