When you say 'associate to VMs', that would be associating to neutron ports, right? If so, this is a subset of what is in:
https://blueprints.launchpad.net/neutron/+spec/neutron-port-template-framework https://blueprints.launchpad.net/neutron/+spec/neutron-port-template-policy which also include things like bandwidth guarantees and security policy. I'm not sure if anyone is pursuing these right now, but there may be some useful ideas in there.

I was thinking about a “network flavor” that a tenant can associate to VMs. Basically the network flavour is a QoS policy. The admin can define the network flavors (Gold, Silver, ... call it as you want) with a set of parameters (some visible to user, some not). If we define this kind of flavours, a related quota should be define to keep track the network resources.

Can you clarify what you mean by cumulative bandwidth for the tenant? It would be possible to rate limit at the tenant router, but having a cumulative limit enforced inside of a tenant would be difficult.

Let’s suppose using rate-limit for managing QoS. The quota parameters could be such as rate_limit (per port) and max_bandwidth (per tenant). 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.org<mailto: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<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
