QOS/Priority Queuing on an Internet Access Router

[a.read]

Hi all,

I'm trying to figure out a way of allocating/prioritising bandwidth on a router that connects our network to the Internet.

I’d like to for example give 60% of the bandwidth to HTTP/HTTPS, 20% to a VPN link, and the rest allocated on a fifo basis. This is for internal users browsing the web, not for external access to our servers.

I have no control over the router at the Internet Service Providers end.

It seems that queuing will not help, as I’m trying to prioritise traffic being received, not sent.

I imagine the bandwidth is limited at the ISP’s end, so I can’t see congestion helping.

Are there any other ways I could achieve what I’m after?

Regards,

Andrew

Andrew,

You should be using CAR (commited access rate, otherwise called policing, or rate limiting).

Basically what CAR does is, you set some threshold values of bandwidth (rate of sending data - can be done for both input and output).

You have the option of transmitting, dropping, setting Ip precedence values etc, once the specified rate is reached or exceeded.

All traffic excceeding a particular rate can be dropped.

thanks for the response,

Looks like what I need. I should have mentioned my router is a 2611 IOS 12.2.

Anything available for something as small as this?

Yes you should be able to do it with 12.2 IOS. (even with IP only version, would do)
