As a distributed system, increasing the number of ONOS nodes can increase overall system performance - shown here latency to discover a topology decreases with number of ONOS nodes. See Test details and other performance related tests, go to: ONOS System Tests.
Hight Availability Tests
ONOS as a distributed system provides high availability for network operations - ONOS is tested against various network failure scenarios. See Test details and other performance related tests, go to: ONOS System Tests.
