Hi, There is a section in Openstack Network installation Guide called "Install Software on Data Forwarding Nodes". I'm wondering What is difference between the concept of "Data Forwarding Nodes" here and the SDN control and forwarding plane? Is it possible to have a node in openstack act as a SDN control plane while another, as forwarding plane (termed "Data Forwarding Nodes" here)? Thanks, Qing -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-dev/attachments/20131005/e144d505/attachment.html>
