Re: [LARTC] wrr question

I've got a full HTB setup currently, and I'm just looking at other
options for greener pastures. The thing at the moment is that we offer
internet to students, and South African bandwidth is probably the most
expensive in the world... We want to limit things to stop abusive
behaviour even before it begins...

My main concern is that since we do overschedule the available
bandwidth, I need everyone's bandwidth to degrade equally, depending
on the amount of users. Currently I basically set my rules like this:

rate = total rate / num of users
ceil = total rate / 8

I'm just worried about the equal degrading of everyones links..

Anycase, I just thought that WRR might offer a smoother experience for
the users, but I'll stick with my HTB setup for now since it's working
beautifully. If anybody has an alternative suggestion, please shout.

Thanks for the reply though.
