> 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.
