5 / 63 ONOS Open Network OS ONOS provides the control plane for a software-de ned network (SDN), managing network components, such as switches and links, and running software programs or modules to provide communication services to end hosts and neighboring networks. ONOS applications and use cases often consist of customized communication routing, management, or monitoring services for software-de ned networks. ONOS can run as a distributed system across multiple servers, allowing it to use the CPU and memory resources of multiple servers while providing fault tolerance in the face of server failure and potentially supporting live/rolling upgrades of hardware and software without interrupting network tra c.

6 / 63 ONOS Architecture Tenets High-availability, scalability and performance (required to sustain demands of service provider & enterprise networks) Strong abstractions and simplicity (required for development of apps and solutions) Protocol and device behaviour independence (avoid contouring and deformation due to protocol speci cs) Separation of concerns and modularity (allow tailoring and customization without speciating the code-base) Ref: ONOS Distributed Tutorial

27 / 63 REST Interface ONOS uses Swagger to auto-generate REST API documentation. This can be viewed from any running ONOS instance at the URL: :8181/onos/v1/docs/ O ers a nice way to directly run queries or copy & paste curl commands for testing. Endpoints contributed by non-core applications can be reached through the top menu. The REST API exists primarily to provide an easy (but slow) way for web applications and scripting languages to interact with the ONOS system. It is not recommended for routing or high-performance network applications, but can be useful for human-timescale tasks such as system management. It can also be useful for testing and debugging.
