Yes, it’s been posted on github[1].</div>

<div class="">IMHO, the design should be what’s best for the whole neutron project looking</div>

<div class=""><br class="">
</div>
<div class="">by this I mean that we should not influence the design by what was already designed D/S, </div>

</div>
<div class="">*but*, I’m sure there are lots of logic that we could reuse from the DSCP perspective, and</div>

<div class=""><br class="">
</div>
<div class="">Absolutely. I’m by no means insinuating that what we have is the only way, or even the ‘right’ way. We had to do it for business requirements so we just got it done and are carrying patches. I’m definitely interested in Salvatore’s suggestion
for starting with how to define things in the API first.</div>

I’m very interested in seeing this feature mature. Sean was writing this code initialy while working with our team here at Comcast and we’re still carrying the patches he wrote through to new versions of Neutron. I’d very much like to discuss ways to bering
them back into mailine.<br class="">

<div class=""><br class="">

<div class="">I agree with starting simple. We’ve implemented basic DSCP marking only at this point to allow hardware switches to to queue and filter based on the marks. It would be great to bring the queueing down into the vSwitch and then extend this to
things like minimum guaranteed bandwidth. I have a fair few applications that would benefit from these kinds of features.</div>

<div class="">There’s no best way. Just pick an open meeting timeslot, email out the meeting details and get your notes/meeting minutes onto the wiki. Hopefully this works out and I’d be glad to help!</div>
