> Carlos: how does this relate to older traffic steering BP. Cathy: we can discuss offline and work together to incorporate the traffic steering BP idea into this BP.

> Isaku: does Kyle know about BPs? Cathy: yes
> 
> Uri: how do these BPs relate to rest of Openstack? Cathy: There will be a presentation on the service chain framework at 2pm May 18 at the Vancouver Summit. It will be presented by Cathy together with Kyle Mestery and Dave Lenrow.
>

> 
> 2.     Swami will send an email to Kyle Mestery requesting a time slot for service chaining topic in Neutron design session so that we can get all interested parties in one room for a good face-to-face discussion.

> 3.     Cathy will discuss with Carlos offline about incorporating the traffic steering idea into the service chain BPs.
> 
> 4.     Service chaining is a complicated solution involving management plane, control plane, and data plane as well as multiple components. The consensus is to first design/implement the two Neutron related service chain BPs https://review.openstack.org/#/c/177946 and get the feature approved by Neutron Core/Driver team and implemented for the OpenStack L release. If we can not get a slot in the design session, we will meet at the service chain presentation on May 18 and find a room to discuss how to move forward with this feature development in OpenStack.
