Hi all,

A new Feature page for "Network Quality of Service" feature was published.

You are more than welcome to share you thoughts and insights.

Thanks,
Ofri.

some questions:
1. "In the Add/Edit Network two parts will be added - one for the QoS
properties of the network, the other for the QoS properties preset for
VNICs attached to the network."

so the first part of QoS for network is the limit of the logical network
on the host for all vnic's associated to it, compared to other logical
networks?

Exactly. first part is the network level limitation.

ok. i guess in most cases it wouldn't make sense for network level and vnic level to be the same?

...


3. "outbound_burst         Bigint "
just wondering - what numbers do you expect here that Integer like the
average and peak is not enough?


the units for the "burst" parameter are Mb (Mega bits). so, if we would like to 
allow burst of over 4GB (Giga byte) we will need Bigint.

integer is up to +2147483647 (Mb)? that's way more than 4GB?

...


5. behavior with provider networks (quantum)?

Traffic shaping using the Network QoS feature will be available only for oVirt 
networks at this stage.

1. please comment as much
2. btw, why? if libvirt is the one setting the traffic shaping, how would it be different for (some) quantum networks like bridge or ovs?

Thanks,
   Itamar
