What is ISSU?
ISSU is an acronym for In-Service Software Upgrades. This means supporting software updates to the ONOS core and its applications without interrupting service. Support for ISSU will include both mechanisms for upgrading core and application state and semantics and rolling back failed upgrades.
Extensive documentation and discussion of the proposed architecture for ISSU in ONOS is available online:
