tinc - Jan 2011 - QOS Wishes

Hello all,

It would be a great feature if QOS could be implemented in Tinc.
It's not to do any sort of comparison, but with OpenVPN, the traffic can
be shapped.

In the way that tinc works as mesh VPN, the great feature would be to
fix a shapping value on each nodes, known and respected by each others.
(like MPLS does)
As an exemple, you've got 3 nodes A,B and C, you want Tinc flows on A
node only use 1000kbits on your link, even if B and C send
simultaneously to A, they will not overrun this limit.

A+

Rate limiting can also be done outside of tinc. If you want to limit your
ingress on A, then on Linux you can use the limit module of iptables to limit
the amount of UDP packets you accept on port 655. You could also use iptables
or tc on the VPN interface.

Personally, this would be a very low priority feature. But if someone wants to
implement it in tinc, I wouldn't mind adding such functionality.
