+This document introduces scenario descriptions for Euphrates 1.0 of
+deployment with the OpenDaylight controller and SFC feature enabled.
+ :depth: 3
+This scenario is used to deploy an Ocata OpenStack deployment with
+OpenDaylight Nitrogen, Ceph Jewel, and SFC feature enabled.
+Scenario components and composition
+This scenario includes a set of common OpenStack services which are Nova,
+Neutron, Glance, Cinder, Keystone, Heat, Ceilometer, Gnocchi, Aodh,
+Horizon. Ceph is used as the backend of Cinder on deployed hosts. HAproxy
+is used to balance all the services running on 3 control nodes behind a
+VIP (Virtual IP address). OpenDaylight will also be deployed in this
+scenario. ODL is also running in HA. Neutron communicates with ODL
+through a VIP. Open vSwitch with NSH patched is used instead of native
+Open vSwitch to support ODL SFC. Neutron communicates with ODL SFC to
+create port pair, classifier, port chain and etc.
+Scenario usage overview
+To deploy with this scenario, you just need to assign the
+os-odl-nofeature-ha.yaml to DHA file before deployment.
+Limitations, Issues and Workarounds
