+SFC Script ReadMe File
+**********************
+
+Topology
+---------
+
+Validated with the Fuel Enviroment.
+
+
+Things to Remember :
+--------------------
+
+1] This Script basically Tests the SFC functionality with ONOS controller.
+2] Ip address of Openstack and ONOS are got dynamically.
+3] Initally this sfc script can be used for ONOS and on Request , if need will modify for other controllers.
