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

I have a patch for this BP:
<a 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 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 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 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 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>
