+Summary:

+        This test uses the null-provider to simulate a network topology
+        and tests the throughput via a python script called flow-tester.py.
 
-Pre-requisites: To run out-of-the box this test requires 7 NODES. 
-    OC1->OC7 must be set before initiating the test. Passwordless login
