[c-nsp] QoS and groups of subscribers

[Mike]

Hello,


    I have a group of subscribers using PPPoE, and I was wondering if
there would be a way to implement a common QoS policy whereby every
member of this group shares a single virtual 100mbps pipe? The situation
I want to deal with is oversubscription and wanting to try and enforce
queuing at the head end router where I know the bandwidth of the
transport network behind it, and wanting to try and improve fairness for
these users so a small group does not drown out everyone else. I know
and already have a working solution for implementing CAR for individual
users (well tested here), but what I am talking about here is for an
entire group sharing one pool of bandwidth.

    I don't really know what I am looking for here other than more
fairly sharing 100mbps amoungst a group of competing users, but in
concept if I am going to do it, then it might be nice to see what can be
done not only for a larger group but also at the level of per subscriber
and see about making more intelligent queuing / shaping decisions to
improve overall service quality for end users who otherwise DDoS
themselves. Would love any pointers or examples of how this has been
done already elsewhere.


Thank you.
