OVP: OPNFV Verification Program

By | Resources

A community-led compliance and verification program to improve quality and interoperability in the NFV ecosystem.

Network functions virtualization (NFV) and software- defined networking (SDN) offer service providers increased service agility, OpEx improvements, and back-office automation. Disaggregation, the approach of decoupling the various layers of the stack, from hardware, to NFVI/VIM software, to dataplane acceleration, SDN controllers, MANO components, and VNFs, enables multi-vendor deployments with best-of-breed options at each layer.

Interoperability has always been a challenge, and as the number of vendors and interfaces between layers increases, those interoperability challenges increase proportionally. In response, OPNFV launched the OPNFV Verification Program (OVP) in early 2018, focusing on commercial NFVI/VIM product offerings. Around that same time ONAP began activities in its Beijing and Casablanca releases to focus on compliance activities for VNF vendors.

As ONAP and OPNFV (as well as several other open source networking projects) have now come together under the LF Networking (LFN) umbrella, they have joined forces to add VNF compliance testing to OVP. This program is the first of its kind to combine automated compliance and verification testing for multiple parts of the NFV stack. OVP provides testing of commercial products built on top of the requirements from the ONAP VNF Requirements project, multiple SDOs such as ETSI and GSMA, and the LF Networking End User Advisory Group (EUAG). OVP has also introduced a Verified Labs program.

This new whitepaper provides a guide for understanding the OPNFV Verification Program, how to get involved, and how to complete verification on your NFVI and VNF products and services.

Harmonizing Open Source and Open Standards: The Progress of ONAP

By | Resources

As part of the broader evolution of open networking, the Linux Foundation networking projects have been working closely with
a range of networking standards groups to align complementary efforts. This work has been described in “Harmonization 2.0: How Open Source and Standards Bodies Are Driving Collaboration Across IT” and “Harmonizing Open Source and Standards in the Telecom World” in 2017.

Following the direction, in 2018, “Harmonizing Open Source and Open Standards: A Case Study of ONAP” provides a closer look at the ONAP (Open Network Automation Platform) project within the Linux Foundation in order to provide concrete details about what standards might be related for ONAP project and what ONAP is doing on harmonizing open source and Open Standards.

This paper elaborates in more detail about the progress and status along the way from both the open source community
and the standard organizations perspectives. We leverage various community use-cases/blueprints as the vehicle and focus on three areas of ONAP-related industry standards and best practices: architecture, model-driven approaches, and APIs. By sharing our experiences to date, we hope to stimulate broader industry contributions towards shared objectives.

Harmonization 2.0: How Open Source and Standards Are Driving Collaboration Across IT

By | Resources

The networking industry is at a significant turning point as network operators spanning telecommunications, cable, enterprise, cloud, and the research community work to redefine the network architecture.

Widespread new technology adoption takes years to succeed, and requires close collaboration among those producing network technology and those consuming it. Traditionally, standards development organizations (SDOs) have played a critical role in offering a forum for discussion and debate, and well-established processes for systematically standardizing and verifying new technologies. In a software driven world, it is infeasible to standardize a priori complex reference architectures and software platforms without a more iterative approach. As a result, industry has been increasingly turning to open source communities for implementation expertise and feedback.

This whitepaper outlines the key concepts, and invites an unprecedented collaboration among the SDOs, open source projects, and industry groups that each play a vital role in the establishment of a sustainable ecosystem which is essential for success. Join us to usher in a new era of collaboration and convergence to reshape the future of networking.

Multiple open source communities and organizations collaborate to bring mobile services to the edge

At Open Networking Summit Europe, Oct 25-27 2018 in Amsterdam, a team made up of 30 volunteers from 15 organizations from the LF Networking project communities unveiled the Virtual Central Office 2.0 proof of concept in a live keynote demonstration. The demo was the next evolution of the Virtual Central Office Demo 1.0 shown in Beijing during the 2017 OPNFV Summit that highlighted residential and enterprise services — this time highlighting the ability to deliver mobile services based on 5G network infrastructure. The demo was then shown again the following week at the Open Compute Project Regional Summit, Oct 1-2, also in Amsterdam.

In this solution brief, discover how four open source communities came together to develop a proof of concept based on one of the industries most pressing use cases and how this approach can help carriers with their VCO strategies.

ONAP Dublin DDF and OPNFV Gambia Plugfest Joint Report

By | Resources

The fourth ONAP DDF and sixth OPNFV Plugfest were co-located at the Nokia facility in Nozay, France. The event spanned four days from January 8-11, 2019.

The focus of this joint event was to bring commercial vendors and open source community members together to plan the upcoming ONAP Dublin release, perform testing and integration of the OPNFV Gambia release, and foster collaboration between the ONAP and OPNFV communities. The combined event was attended by 213 individuals from 55 organizations that included 11 end-users and 11 research and nonprofit organizations.

An important outcome of the joint event was the collaboration between the OPNFV and ONAP communities and there was interest in both communities to come together and leverage each other’s work. Joint activities ranged from extending the OPNFV Verified Program (OVP) to verify ONAP VNF compliance; using OPNFV test tools such as Functest, Yardstick, and Dovetail for ONAP; adopting the OPNFV CI pipeline for ONAP; and collaborating around cloud native and edge computing technologies.


Benchmarking Software Data Planes Intel® Xeon® Skylake vs. Broadwell1

By | Resources

Software data plane performance and efficiency are foundational properties of any NFV and cloud networking system design. They do not only impact network service economics by dictating feasible service density per unit of compute, but can also be a key enabler of new service architectures.

A good example is the cloud-native architecture based on distributed micro-services, that require meshed IP connectivity for scaled-up inter-process communication and data exchange. Those systems heavily rely on service-aware software data plane for L2 switching, IP routing, load balancing and granular in-band policies used for securing all application interactions.

The exponential Internet traffic growth is still one of the main challenges for the Telco industry. In the past, Moore’s Law has helped us to keep our production cost for the exponentially growing traffic under control. With Moore’s Law flattening out, we see a strong trend in the industry towards the disaggregation of hardware and software. From monolithic black-box solutions, we are moving towards a modular, best-in-class, flexible and open ecosystem, including an automated lifecycle management in true DevOps style. None of the Telcos can do this on their own – the success of this industry depends on collaboration.

Beside its engagement in the Telecom Infra Project (, Deutsche Telekom has now joined the Linux Foundation as a Silver member, and The Linux Foundation Networking Fund (LFN) as a Platinum member to drive the development of open source software for the telecommunication market. Existing projects like ONAP,, Open Daylight as well as upcoming projects on Edge Computing and AI are important for our success.

After all, open source is about community. So, together with the worldwide open source community, we look forward to contributing to solve the greatest technology challenges around virtualization, as well as evaluating the potential to incorporate open source code into our networks. As founding member of O-RAN, we are already leading the drive to introduce more openness and flexibility into the radio access domain, and participating also in ONF for an enhanced network programmability within our infrastructure. Joining the LFN now complements Deutsche Telekom’s embrace of open source software as a key technology in our architectural vision for future networks.

The work in ONAP, together with our activities in ETSI-ZSM, will lead the industry towards a fully automated network and service management. One thing is very clear to me: Intelligent and automated networks will be the critical success factor to leverage the full benefits of 5G, for our customers, both consumers and verticals. And we believe in joining forces with partners in the industry to bring in innovation and accelerate the path to this shared future!

Solution Brief: A Virtual Central Office Results in Reduced Total Cost of Ownership

By | Resources

Central offices (COs) provide critical access/aggregation networking services (e.g. for cable, fiber, DSL, wireless customers) and there are more than 10,000 COs in the United States alone. Network services in a central office have traditionally been built using proprietary, complex and single-function boxes but that is changing with the advent of the virtual Central Office (VCO) that brings service agility, improved customer experience, and a significant reduction in costs. Using a OPNFV Enterprise VCO concept first demonstrated at the OPNFV Summit — and run through a TCO calculator from Intel — a new Solution Brief has been developed that shows how CSPs can deliver network services to their customers at up to 43% lower total cost of ownership (TCO).
