-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.
