<div>Eugene,</div>
<div><br>
</div>
<div>First of all, I was surprised that we do not have any support for h/w LBs and VIrtual LBs.</div>
<div><br>
</div>
<div>Now, we badly get into Architecture discussion again for addressing all these concerns before we go for the summit.<br>
<br>
Pls let me know suggestions/comments.<br>
<br>
</div>
<div>Thanks

<div>I'm not sure I understood your question.</div>
<div>Currently quantum's lbaas plugin supports the only type of loadbalancer and it's not customizible via drivers at this point.</div>

<div>Hi Ilya,</div>
<div> </div>
<div>As described in the document given in the below link:</div>
<div> </div>
<div><a href="http://wiki.openstack.org/Quantum/LBaaS/Agent" target="_blank">http://wiki.openstack.org/Quantum/LBaaS/Agent</a></div>
<div> </div>
<div>Agent part will be running on Compute Node or Controller Node ?.</div>
<div> </div>
<div>I guess it should be on the Controller Node only. As the driver abstraction layer is for choosing the right driver for the device it has to connect like Driver A to the Device Type A. etc. [This approach is for HW device LB]</div>
<div> </div>
<div>If we want to have SW-based-LB like SLB VM, does the above architecture is valid?</div>
<div> </div>
<div>Can you please through some light on the Agent part of the architecture like where exactly the agent will be running like OpenStack Controller Node or OpenStack Compute Node.?</div>
<div> </div>
<div>Thanks in advance.</div>

Hi Pattabi,
<div><br>
</div>
<div>Code for LBaaS agent and driver API is on review. You may check it from Gerrit topic <a href="https://review.openstack.org/#/c/20579" target="_blank">https://review.openstack.org/#/c/20579</a>. Instructions on how to run the code in DevStack environment
