QOS by IP without automatic classification
« on: July 25, 2010, 07:28:04 PM »

I just want to confirm that QOS doesn't need to be enabled on individual machines when QOS is enabled on the router, WITHOUT "automatic classification" enabled.

If I wanted to kid myself, I would wrongfully say "yeah, to use QOS in any way, I need to have it enabled on each computer" without any basis for that claim other than presumption.  Because of how I want it configured, however, I am under the same presumptuous impression that QOS is unnecessary for this configuration I have in the router.

My understanding is that QOS-tagged packets sent from the computer identify the type of traffic, more so than what the router could infer based solely upon the port number and protocol.  If the router is only setup to adjust packet prioritization based on IP and port numbers alone, QOS can effectively be disabled on all computers, correct?

(incase someone says "why would you want to do that?", I use cfos speed for packet prioritization on my main computer, and simply want to lower the priority of my web server and others below the main one in general, without any care for what type of data is flowing from them)

Can a D-Link developer confirm/deny the internal functionality of D-Link's QOS engine in this way, without automatic classification or relying upon QOS-tagged packets?  Typically, I don't think the majority of users disable QOS and ipv6 in the adapter settings, and then go on to disable IP Helper entirely to disable tunneling as I have...I'm looking to minimize all unnecessary overhead since I want to prioritize by IP rather than data type.

Not a Dlink tech, but QoS on the client is different from the QoS engine used on the DIR655. AFAIK, they do not interact at all.

QoS on the client needs more configuration anyway, so out-of-the-box it does not give any advantage unless called by a specific routine. Your Cfos does that, prioritizing the dataflow that is sent through your NIC.
