From Portal to SDC: Inside the ONAP Architecture

By Blog

See below for a quick overview of ONAP informational videos from Architecture sub-committee members Manoop Talasilla and Michael Lando.

The ONAP platform is made of several software subsystems and two major architectural frameworks – a design-time environment to design, define and program the platform; and an execution-time environment to execute the logic programmed in the design phase. Whether new to the platform or well-versed, understanding the ONAP architecture is critical to deployment, and our latest video series is here to help.

To kick off the series, we’ll focus on the ONAP Portal and Service Design and Creation (SDC). The videos feature two key members of the ONAP Architecture Team:  Manoop Talasilla, Portal Technical Lead at AT&T Research Labs, and Michael Lando, Service Design Technical Lead of AT&T. In our video series, Manoop covers the ONAP portal, and Michael the Service Design and Creation (SDC).

Video 1: ONAP Portal

Manoop takes a beginners look at the ONAP portal, focused on the platform and its ability to integrate different applications into a centralized portal core. Additional capabilities of the portal include application onboarding and management, decentralized access management, and hosed application features, as detailed in the video.

Video 2: Service Design and Creation (SDC)

SDC, and Integrated Development Environment (IDE), is a subsystem of the design-time framework, accessible through the ONAP portal. In the video, Michael discusses that as an IDE, SDC provides the tools for designing services as well as creating the necessary artifacts for service orchestration. With its graphical interface and visual tools, users can drag and drop different components onto the SDC canvas to model their service, see what’s connected where, what the capabilities are and the requirements each VNF provides to the service.

As the design time component, SDC handles all design time activities. Check out the full video below to hear Michael’s explanation of SDC in ONAP.

Introducing The Linux Foundation’s Open Source Networking Days

By Blog

This post, by Arpit Joshipura, first appeared on

One of my primary goals at The Linux Foundation is to foster innovation across the entire open source networking ecosystem. This involves coordinating across multiple open source projects and initiatives and identifying key areas for collaboration to create an open source networking stack.

We are working across the entire ecosystem with industry-leading partners — from developers to service providers to vendors — to unify various open source components and create solutions that will accelerate network transformation. As part of this journey, I am pleased to introduce Open Source Networking Days (OSN Days), a series of free events that are hosted and organized by local user groups and The Linux Foundation members, with support from our projects, including DPDK,, ONAP, OpenDaylight, OPNFV, PNDA, and others.

OSN Days are a fantastic opportunity for network developers and users to learn how ONAP, OPNFV, OpenDaylight  and other open source initiatives are changing NFV/SDN orchestration and networking solutions. Stops on the tour include: ParisMilan, Stockholm, London, Tel Aviv, and Japan. Register today for an upcoming OSN Day in your region.

The day-long events will start with a plenary session where attendees will hear from site hosts and The Linux Foundation speakers on the state of the industry and the collaboration and touch points between projects that make up the open source networking stack. Presenters will also explore how business opportunities like 5G and IoT are enabled by network transformation.  In the afternoon, events may feature technical sessions, tutorials, demonstrations, and workshops that empower attendees to participate, contribute, and deepen their knowledge of open source networking.

Our first OSN Day kicks off October 9 in Paris, followed by stops in Milan (October 12), Stockholm (October 13), London (October 16), Tel Aviv (October 19), and Japan (October 19). Thanks to our incredible site hosts Amdocs, ATOS, Cloudify, Ericsson, Huawei, NEC, Orange, RedHat, SUSE and Vodafone, along with our high-caliber roster of speakers, for helping to make these OSN Days a reality!

More details about the events, including site-specific agendas, registration info, and details on hotel and travel, can be found here: If you have any questions, or would like to host an event yourself in the future, please email

Fierce Wireless: AT&T confident in ONAP’s ability to attract more operators

By In The News

AT&T is so confident in Open Network Automation Platform (ONAP), an operating system for automating virtual network functions, that it believes more players will jump on board to support it in the coming weeks.

“I think ONAP becomes basically the de facto standard for SDN for operators,” AT&T Labs President and CTO Andre Fuetsch told FierceWirelessTech. “I’m predicting that the majority of operators around the world will sign onto ONAP.”

Webinar: ONAP Poised to Transform Industry

By In The News

Earlier this year, the Linux Foundation announced that it was merging open source ECOMP with OPEN-O to create a powerful automation platform for telcos’ NFV and SDN networks. During this Telco Transformation radio show, AT&T’s Mazin Gilbert and the Linux Foundation’s Arpit Joshipura will discuss some of the key concepts of ONAP, including the recent formation of its technical steering committee as well as opening up the code and documentation to the industry.

Other highlights of this radio show include:

  • Industry involvement – ONAP’s members include the largest global services providers and technology leaders
  • Goals of ONAP – Becoming the network operating system for SDN automation
  • Accessing the code – Developers can now access the production-ready code, along with instructional materials and videos

Light Reading: AT&T Confidence Builds on ONAP Adoption

By In The News

AT&T’s announcement of its $200 million commitment to a venture capital fund backing tech startups grabbed some headlines last week, but on closer inspection, this is practically business as usual for the telecom giant.

What’s different this time around is that AT&T is expecting whatever solutions are developed to run on top of the Open Network Automation Platform ( ONAP) it helped launch earlier this year with the Linux Foundation — because AT&T is convinced this is going to be the operating system most telecom providers will be using.

Light Reading: Windstream Formally Embraces Open Source

By In The News

Windstream is dipping its toe into the open source waters, joining the Open Network Automation Project (ONAP), its first active engagement in open source. (See Windstream Joins ONAP.)

The announcement could be the sign of broader engagement by US service providers in the open source effort. At Light Reading’s Big Communications Event in May, a CenturyLink speaker said his company is also looking closely at ONAP. (See Beyond MANO: The Long Walk to Network Automation.)
