2 What is ONOS? Open Network Operating System (ONOS) is an open source SDN network operating system. Our mission is to enable Service Providers to build real SDN/NFV Solutions. ONOS Framework (ONOSFW) is the OPNFV project focused on ONOS integration. It is targeted for inclusion in the Brahmaputra release.

4 Quarterly Releases Avocet (1.0.0) released in December 2014 Initial release of clean & modular code-base, protocol independence Blackbird (1.1.0) released in March 2015 Improved performance, scale-out, increased robustness Cardinal (1.2.0) released in June 2015 New use-cases, additional core features, additional SB protocols Drake (1.3.0) released in September 2015 Platform enhancements, security features, UI enhancements Emu (1.4.0) - currently in progress for December 2015 Dynamic cluster scaling, Virtual Network and CORD features

5 Architectural 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 specifics Separation of concerns and modularity allow tailoring and customization without speciating the code-base

9 Key Northbound Abstractions Network Graph Directed, cyclic graph comprising of infrastructure devices, infrastructure links and end-station hosts Flow Objective Intent Device-centric abstraction for programming data-plane flows in table pipeline-independent manner Network-centric abstraction for programming data-plane in topologyindependent manner

10 Device Protocol Support Included - OpenFlow - 1.0, 1.3+, driver-based pipeline support via Flow Objectives - OVSDB - NetConf - PCEP - TL1 (available from select vendors) Under development - BGP-LS - SNMP (v2c)

11 Approaches to Virtualization 1. Overlay (implemented) OpenStack/Nicira-style virtualization Collection of ports with L2/L3/etc. connectivity No topology 2. Hypervisor (in progress) OpenVirtex-style virtualization Virtual topology elements (devices, ports, links) No implied connectivity
