Re: [openstack-dev] [Neutron][QoS] Applying QoS as Quota
Kevin, I'm aware of the blueprint. Actually I've tried to make it work, but the rules are not applied to the OVS bridge. Moreover there are these limitations: 1. it considers only dscp and rate limit 2. it doesn't introduce a way to manage these policy (i.e. from the admin side) Anyway it's a good starting point. I hope it will be extended (not sure whether the incubation proposal passed or not).

Right! If the wikihttps://wiki.openstack.org/wiki/Neutron/QoS is up to date, you can look there.

In this way it is possible to set/manage QoS quotas from the admin side, and for instance set the maximum bandwidth allowed per tenant (cumulative). What do you think about it? I’m cautious about this. We’d either need to allow a “Number of DSCP settings” and set them outside the quota or leave it out altogether. Let’s not forget that there’s more than just rate limiting in QoS, and we need to make sure all the options are included. Otherwise, there’s going to be a lot of user and operator confusion as to what is and isn’t considered part of the quota. -Anthony Regards, Giuseppe Giuseppe Cossu CREATE-NET ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.orgmailto:OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev -- Kevin Benton ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
