Check connectivity from one VM to an external host on | +| | the Internet to verify SNAT functionality. | +| | | +| | Result: The monitor info will be collected. | +| | | ++--------------+--------------------------------------------------------------+ +|step 2 | Start attackers: | +| | SSH connect to the VIM compute nodes and kill the Vswitch | +| | processes | +| | | +| | Result: the SDN Vswitch services will be shutdown | +| | | ++--------------+--------------------------------------------------------------+ +|step 3 | Verify the results of the IP connectivity monitors. | +| | | +| | Result: The outage_time metric reported by the monitors | +| | is not greater than the max_outage_time. | +| | | ++--------------+--------------------------------------------------------------+ +|step 4 | Restart the SDN Vswitch services. | +| | | ++--------------+--------------------------------------------------------------+ +|step 5 | Create a new VM in the existing Neutron network | +| | | ++--------------+--------------------------------------------------------------+ +|step 6 | Verify connectivity between VMs as follows: | +| | 1. Check the L2 connectivity between the previously | +| | existing VM and the newly created VM on the same | +| | Neutron network by sending ICMP messages | +| | | ++--------------+--------------------------------------------------------------+ +|step 7 | Stop IP connectivity monitors after a period of time | +| | specified by “monitor_time” | +| | | +| | Result: The monitor info will be aggregated | +| | | ++--------------+--------------------------------------------------------------+ +|step 8 | Verify the IP connectivity monitor results | +| | | +| | Result: IP connectivity monitor should not have any packet | +| | drop failures reported | +| | | ++--------------+--------------------------------------------------------------+ +|test verdict | This test fails if the SLAs are not met or if there is a | +| | test case execution problem. The SLAs are define as follows | +| | for this test: | +| | * SDN Vswitch recovery | +| | * process_recover_time <= 30 sec | +| | | +| | * no impact on data plane connectivity during SDN | +| | Vswitch failure and recovery. | +| | * packet_drop == 0 | +| | | ++--------------+--------------------------------------------------------------+ + |
