QoS and setting it up

I am curious how exactly it is best to run QoS on a link.

The link coming in to our site is a 10meg. now I of course only have rights to set up traffic shaping / QoS on my end of the link, however the main trouble is with incomming traffic, mainly web traffic, (little out lots in).

how can I set up traffic shapeing to limit this traffic in and prevent it clogging up the link for all traffic.

Am i correct in thinking that if you set incomming shaping, beacause inbound traffic will be que by the router in its bufferes, and "good traffic" will be moved to the frount and "bad" traffic will be dropped? And this will allow incomming traffic as well as out going to be shaped?

Or do I need to have the ISP also run traffic shapeing ?

Or how else can I make sure I have control of traffic both in and out of site..

What I want to do i limit non work web browseing and insure it can only use a % of the total band with.

Cheers

technically it is feasible to conduct traffic shaping on incoming web access. but, this will significantly impact on web user experience. is it a good practice for your organization?

I wasn't just really thinking of web traffic but in generaly. can you shape incomming traffic from only one end of the link.

our link in to site is shared by web, application, and video traffic. i want to think about shaping all of it, but I didnto know if the ISP needs to be involved, or will just runnin shaping on traffic comming in to my router from the ISP work ?

sorry for replying late.

in regard to traffic shapping, there are two approaches: hardware based and software based.

obviously the HW based solutions are comprehensive and efficient but expensive. an outstanding product line is PacketShaper

FYI - Network Performance Monitoring | PacketShaper Features

SW based solutions are cheaper but commonly not suitable for enterprise environment because of lack of high performance and comprehensive rules. an example is SoftPerfect Bandwidth Manager

hope it helps,
