The BP name is a little confusing. It is not all about
scheduler. But it needs us to have a scheduler.<br>

<div>Yong, you should be able to rename the blueprint URL using
the "edit details" link: <a moz-do-not-send="true"

I have a patch for this BP: <a moz-do-not-send="true"
href="https://review.openstack.org/#/c/18216/"
target="_blank">https://review.openstack.org/#/c/18216/</a><br>
<br>
please see the schedule_xxxx methods in this file:<br>
<a moz-do-not-send="true"
href="https://review.openstack.org/#/c/18216/3/quantum/db/multipleagents_db.py"
target="_blank">https://review.openstack.org/#/c/18216/3/quantum/db/multipleagents_db.py</a><br>
<br>
I composed a draft admin guide (attached) for the BP,
please have a look at: Appendix A. Demos Setup ->Scale
and HA of agents.<br>
<br>
I read your <a moz-do-not-send="true"
href="http://wiki.openstack.org/Quantum/LBaaS/Architecture/Scheduler"
target="_blank">http://wiki.openstack.org/Quantum/LBaaS/Architecture/Scheduler</a>
and have this:<br>
1. Quantum scheduler can be multischeduler, just like one
in nova-scheduler although it schedules only VM to compute
hosts now.<br>
2. With multischeduler, we can have sub schedulers. for
example sub scheduler for allocating networks to DHCP
agents<br>
sub scheduler for allocating quantum routers to l3
agents, and subscheduler for allocating 'pool' to devices<br>
So here it is: <br>
class multischeduler(object):<br>
scheduler['network'] =
import_class(conf.network_scheduler)<br>
scheduler['router'] = import_class(conf.router_scheduler)<br>
scheduler['pool'] = import_class(conf.pool_scheduler)<br>
<br>
3. Then the sequence diagram is calling scheduler['pool'].<br>
My BP is calling other two.<br>
<br>
Thanks<br>

<div>I see you've started working on <a
moz-do-not-send="true"
href="https://blueprints.launchpad.net/quantum/+spec/quantum-scheduler"
target="_blank">https://blueprints.launchpad.net/quantum/+spec/quantum-scheduler</a></div>
<div> <br>
</div>
<div>We also thought on designing/implementing
scheduler for load balancer service.</div>
<div>Although we're working on it within LBaaS effort,
we're designing scheduler to be a framework where
service-specific scheduling algorithms may
easily be plugged.</div>
<div><br>
</div>
<div>Could you briefly go over <a
moz-do-not-send="true"
href="http://wiki.openstack.org/Quantum/LBaaS/Architecture/Scheduler"
target="_blank">http://wiki.openstack.org/Quantum/LBaaS/Architecture/Scheduler</a> and
share your thoughts?</div>
<div> I think it would be better to have one
scheduling component in quantum rather than a set of
shedulers for each kind of service.</div>
<div><br>
</div>
<div>Also I have a question regarding quantum
scheduler architecture proposal (both options1 and
2) in blueprint spec:</div>
<div>why does it need to be a separate process?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Eugene.</div>
