NB – Application Intent Framework Southbound Core API Protocols Adapters Apps Protocols Adapters Protocols Adapters Protocols Adapters ONOS Instance 1 ONOS Instance 2 ONOS Instance 3 ONOS Instance N Distributed Core (performance, scale-out, availability, state management, notifications) ONOS Distributed Architecture
9. Scale-­‐Out  Design  w/  Mul3ple  ONOS  Instances   ONOS Apps Apps Global Network View / State Global Network View / State Each instance is identical One can add and remove instances seamlessly Each instance is a master for a subset of switches It works like a single system for apps and network devices ONOS Instance 1 ONOS Instance 2 ONOS Instance 3
10. ONOS  Architecture  Tiers   Northbound - Application Intent Framework (policy enforcement, conflict resolution) OpenFlow NetConf . . . Apps Apps Distributed Core (scalability, availability, performance, persistence) Southbound (discover, observe, program, configure) Northbound Abstraction: - network graph - application intents Core: - distributed - protocol independent Southbound Abstraction: - generalized OpenFlow - pluggable & extensible
