We would like to set up a Linux Bridge to replace a FreeBSD/ipfw box doing shaping. Currently, we can only chape per IP/protocol on the FreeBSD box, and not by type of traffic (local/international).
Our upstream provider, Internet Solutions (www.is.co.za) differentiates between Local and International Bandwidth as follows:
"Local traffic DSCP bit is set to 20. International is set to 18."
What steps would be involved in, say, setting up shaping to a host to give it a 32kb International and 64 local. Would it be possible to allow bursting when bandwidth is available?
I have read the LARTC Guide at lartc.org, which has an example of how to shape an particular host, but not how to incorporate matching the DSCP bit.
I'm assuming iptables is used to match the DSCP bit, something like the following:
# iptables -t mangle -A INPUT -m dscp --dscp 16 -j ????
Once it is matched, though, how does on force it into a queue? Or am I thinking of this in the wrong way?
