Yardstick Test Case Description TC050
*************************************

+-----------------------------------------------------------------------------+
|OpenStack Controller Node Network High Availability                          |
|                                                                             |

|test case id  | OPNFV_YARDSTICK_TC050: OpenStack Controller Node Network     |
|              | High Availability                                            |
+--------------+--------------------------------------------------------------+
|test purpose  | This test case will verify the high availability of control  |
|              | node. When one of the controller failed to connect the       |
|              | network, which breaks down the Openstack services on this    |
|              | node. These Openstack service should able to be accessed by  |
|              | other controller nodes, and the services on failed           |
|              | controller node should be isolated.                          |
+--------------+--------------------------------------------------------------+
|test method   | This test case turns off the network interfaces of a         |
|              | specified control node, then checks whether all services     |
|              | provided by the control node are OK with some monitor tools. |
+--------------+--------------------------------------------------------------+
|attackers     | In this test case, an attacker called "close-interface" is   |
|              | needed. This attacker includes three parameters:             |
|              | 1) fault_type: which is used for finding the attacker's      |
|              | scripts. It should be always set to "close-interface" in     |
|              | this test case.                                              |
|              | 2) host: which is the name of a control node being attacked. |
|              | 3) interface: the network interface to be turned off.        |
|              |                                                              |
|              | There are four instance of the "close-interface" monitor:    |
|              | attacker1(for public netork):                                |
|              | -fault_type: "close-interface"                               |
|              | -host: node1                                                 |
|              | -interface: "br-ex"                                          |
|              | attacker2(for management netork):                            |
|              | -fault_type: "close-interface"                               |
|              | -host: node1                                                 |
|              | -interface: "br-mgmt"                                        |
|              | attacker3(for storage netork):                               |
|              | -fault_type: "close-interface"                               |
|              | -host: node1                                                 |
|              | -interface: "br-storage"                                     |
|              | attacker4(for private netork):                               |
|              | -fault_type: "close-interface"                               |
|              | -host: node1                                                 |
|              | -interface: "br-mesh"                                        |
