HA Sanity Test

This tests runs through all the state and functionality checks of the HA Test suite but waits 60 seconds instead of inducing a failure. This is run as a 7 node ONOS cluster.

Minority of ONOS Nodes restart

Restart 3 of 7 ONOS nodes by killing the process once the system is running and stable.

Entire ONOS cluster restart

Restart 7 of 7 ONOS nodes by killing the process once the system is running and stable.

Single node cluster restart

Restart 1 of 1 ONOS nodes by killing the process once the system is running and stable.

Control Network partition

Partition the Control Network by creating IP Table rules once the system is in a stable state.

During Partition:

• Topology is replicated within the sub-cluster the event originated in
• Get flows will only show flows within a sub-cluster
• Intents should only be available in the majority cluster (Intent behavior is not fully defined for the raft implementation)
• Mastership behavior has not been defined for split-brain scenario

After partition is healed:

• Topology is consistent across all nodes and should reflect the current state of the network(including updates during partition)
• Flows view should be consistent across all nodes
• Intents should be available on all nodes including any new intents pushed to the majority sub-cluster
• Mastership should be consistent across all nodes

Partial network partition

Partially partition the Control Network by creating IP Table rules once the system is in a stable state. (A and B can't talk, but both can talk to C)

• Topology should be consistent across all nodes
• Flows view will show reachable controllers (A sees AC and B see BC and C sees ABC)
• Intents(Wait for Raft implementation, but will depend on which node is the raft leader)
• Mastership(Wait for Raft implementation)

Description

Passing Criteria

Roadmap

• All Switches, Links, and Ports are discovered
• All information (DPIDs, MACs, Port numbers) are correct
• ONOS correctly discovers any change in dataplane topology
• Each node in an ONOS cluster has the same correct view of the topology

• Devices have one and only one ONOS node as master
• Mastership correctly changes when device roles are manually changed
• Mastership fails over if current master becomes unavailable
• Each node in an ONOS cluster has the same view of device mastership

Intents

• Intents can be added between hosts
• Hosts connected by Intents have dataplane connectivity
• Intents remain in the cluster as long as some ONOS nodes are available
• Connectivity is preserved during dataplane failures as long as at least one path exists between the hosts

now

Switch Failure

• Topology is updated and intents are recompiled

• Topology is updated and intents are recompiled

now

Applications can run for leadership of topics. This service should be safe, stable and fault tolerant. 

• The service is functional before and after failures, nodes can withdraw and run for election
• There is always only one leader per topic in an ONOS cluster.
