Red Hat demonstrated OpenDaylight (ODL) as an SDN Controller for OpenStack. We showed the integration of the Boron release of OpenDaylight with the Mitaka release of OpenStack. The primary objective of the demo was to show how NetVirt can easily create and manage virtual networks that are flexible, secure and scalable.

ODL is part of Red Hat’s overall OpenStack/NFV Solu=on
1 Validated VNFs run on operating systems other than Red Hat Enterprise Linux.
2 Certified VNFs are tested, verified, and supported on Red Hat Enterprise Linux.
3 Future development.
4 partners can certify products through the Red Hat Connect for
5 Enhanced platform awareness delivers performance improvements through CPU pinning,
memory hugepages, and
non-uniform memory access (NUMA) affinity.
6 Single-root input/output virtualization.
7 Service function chaining with OpenDaylight is in Technology Preview.

Demonstrate network virtualization using vxlan overlay, L3 and floating ip
● Three nodes in a single ova that can be consumed by vm players:
○ openstack control, compute, OpenDaylight, CentOS 7, devstack
○ openstack compute, CentOS 7, devstack
○ router for external access, CentOS 6.5
