Rationale: Let's assume we have a working group with multiple sinks. We try to delete the sinks all together, also in this case for each sink a sink removed event is generated. For each event we create a new next objective removing the ports no more needed. Solution is related to the previous patch (group editing). Failure scenario: Sink1 removed -> fwdObj A -> Next B McastHandler store has been updated at this point. Sink2 removed -> remove fwdObj A The remove operations is executed immediately but the Next B could not exist at this point -> flow installation failed Change-Id: Icf568b26b2f3ae3feb935b13038db6195125a5c4
ONOS : Open Network Operating System
What is ONOS?
ONOS is a new SDN network operating system designed for high availability, performance, scale-out.
Top-Level Features
- High availability through clustering and distributed state management.
- Scalability through clustering and sharding of network device control.
- Performance that is good for a first release, and which has an architecture that will continue to support improvements.
- Northbound abstractions for a global network view, network graph, and application intents.
- Pluggable southbound for support of OpenFlow and new or legacy protocols.
- Graphical user interface to view multi-layer topologies and inspect elements of the topology.
- REST API for access to Northbound abstractions as well as CLI commands.
- CLI for debugging.
- Support for both proactive and reactive flow setup.
- SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
- IP-Optical use case demonstration.
