#ONOSProject 3

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.

#ONOSProject 4

distributed core provides high-availability, scalability and performance

abstractions & models allow applications to configure and control the network

without becoming dependent on device specifics applications platform

allows developers to dynamically extend the base capabilities

#ONOSProject 5

Releases

● Avocet (1.0.0) released 2014-12○ initial release of clean and modular code-base, protocol independence ● Blackbird (1.1.0) released 2015-03○ improved performance, scale-out, increased robustness ● Cardinal (1.2.0) released 2015-06○ new use-cases, additional core features, additional SB protocols ● Drake (1.3.0) released 2015-09○ platform enhancements, security, UI enhancements ● Emu (1.4.0) - released 2015-12○ CORD features, prototype of dynamic cluster scaling

#ONOSProject 6

Releases

● Falcon (1.5.0) - released 2016-03 ○ dynamic cluster scaling, model extensibility, YANG compiler incubation ○ secure mode ONOS enhancements ○ new southbound protocols: OSPF, REST & SNMP ● Goldeneye (1.6.0) - released 2016-06 ○ distributed core enhancements ○ compiling intents to flow objectives ○ spring cleaning, YANG compiler incubation, GUI scaling, P4 PoC● Hummingbird (1.7.0) - released 2016-09 ○ new distributed primitives, Kafka & RabbitMQ integration ○ new GUI L&F, incubation of new GUI scalability features ○ build tooling migrated from Maven to Buck for faster builds

#ONOSProject 7

Releases

Ibis (1.8.0) planned for 2016-12

● Dynamic Configuration of Devices and Services○ allow new YANG models for devices and services to be introduced at runtime so that applications can leverage new models and features without recompilation ● Virtualization○ provide SDN-capable virtual networks and virtualized services for each network; introduce virtual networks as a first class abstraction ● GUI Scalability Enhancements○ provide support for nested layouts & regions ● Intent Framework Enhancements ○ enhance existing intent framework to enable new deployments that require SDN-IP & VPLS capabilities

Global SDN Deployment Powered by ONOS

#ONOSProject 9

Global ONOS- based products

-The Agile Controller 3.0, launched today at the Huawei Connect show, fits into the company’s theme of taking open source components and building products around them to deliver cloud-based services. The Agile Controller is based on the open source ONOS controller managed by the Linux Foundation(https://www.sdxcentral.com/articles/news/huawei-launches-commercial-sdn-controller/2016/09/)

-NTT Comm has decided to do a field trial in Tokyo of a very disruptive packet-optical network that is built using open-flow enabled disaggregated ROADMs and white box packet switches with ONOS based SDN control plane.

#ONOSProject 10

The Federated Testbed Initiative

● Goal: Create a federated 5G playground for the industry. Experiment SDN, NFV and cloud technologies in a multi-domain, multi-vendor environment, looking forward to 5G.

● Based on the SoftFIRE testbed infrastructure

● Integration of ONOS and CORD○ Control of the infrastructure○ Act as platform to evaluate for Users

● Driven by EIT Digital

● First Participants:○ Deutsche Telekom○ Ericsson○ Fraunhofer FOKUS○ IEEE○ Politecnico di Torino○ TIM (JolNET)○ University of Surrey

#ONOSProject 11

Roadmap Items

● Dynamic Configuration (in progress) ● Virtualization (in progress) ● GUI Scalability (in progress) ● In-Service Software Upgrade ● gRPC API ● Federation (hierarchical & peering) ● Intent Subsystem 2.0 (a.k.a Intent Domains) ● Distributed Platform & Network Core Seperation
