Top Predictions for Networking in 2018

By | Blog

Arpit Joshipura, GM of Networking and Orchestration at the Linux Foundation, shares his 2018 predictions for the networking industry.

1. 2015’s buzzwords are 2018’s course curriculum.
SDN, NFV, VNF, Containers, Microservices — the hype crested in 2016 and receded in 2017. But don’t mistake quiet for inactivity; solution providers and users alike have been hard at work with re-architecting and maturing solutions for key networking challenges. And now that these projects are nearing production, these topics are our most requested areas for training.

2. Open Source networking is crossing the chasm – from POCs to Production.
The ability for users and developers to work side by side in open source has helped projects mature quickly — and vendors to rapidly deliver highly relevant solutions to their customers. For example:

3. Top networking vendors are embracing a shift in their business models…

  • Hardware-centric to software-centric: value-add from rapid customization
  • Proprietary development to open-source, shared development
  • Co-development with end users, reducing time to deployment from 2 years to 6 months

4. Industry-wide adoption of 1-2 Network Automation platforms will enable unprecedented mass customization.
The need to integrate multiple platforms, taking into account each of their unique feature sets and limitations, has traditionally been a massive barrier to rapid service delivery.

In 2018, mature abstractions and standardizing processes will enable user organizations to rapidly on-board and orchestrate a diverse set of best-of-breed VNFs and PNFs at need.

5. Advances in cloud and carrier networking are driving skills and purchasing shifts in the enterprise.
The ease and ubiquity of public cloud for simple workloads has reset end user expectations for Enterprise IT. The carrier space has driven maturity of open networking solutions and processes. Enterprise IT departments are now at a crossroads:

  • How many and which of their workloads and processes do they want to outsource?
  • How can they effectively support those workloads remaining in-house with the same ease and speed users expect?
  • What skills will IT staff need, and how will they get them?

Which brings us to…

6. Prediction #1 will also lead off our Predictions list for 2019.

Announcing Amsterdam, ONAP’s First Code Release

By | Blog

We are pleased to announce the launch of Amsterdam, ONAP’s first united platform. We are incredibly proud of the community for all of the hard work that has gone into this release, which launched just eight months ago. A Herculean effort from a diverse and growing community, Amsterdam not only merges two separate, existing projects (OpenECOMP and Open-O), but re-architects and optimizes the code base into a single, flexible and modular platform. Amsterdam delivers a unified architecture for end-to-end, closed-loop network automation — which is becoming a mandatory requirement before 5G and IOT deployments — and by doing so, celebrates a new milestone for open source networking.

None of this could have been possible without vast support and contributions of time, resources, and passion from across the growing, global ONAP community. Since coming together, ONAP is now comprised of:

  • 58 members (Turk Telekom just joined as the newest Platinum), including major global carriers, collectively representing more than 55 % of the world’s mobile subscribers
  • All top 10 networking vendors, plus leading global services firms
  • 538 contributors from 46 different organizations (including 7 carriers)

With Amsterdam, ONAP is already delivering on its promise to accelerate the development of a vibrant ecosystem around a globally shared architecture and implementation for network automation. Additionally, ONAP is the first open source project to unite the majority of operators (end users) with the majority of vendors (integrators) in building a real service automation and orchestration platform.

Key Features of Amsterdam

So let’s get to the heart of the release–the key features.  At a high level, Amsterdam is the first vendor-agnostic, policy driven network orchestration and automation platform with closed loop automation.  

For ONAP’s first platform release, it was crucial to lay out a framework that would benefit not only the technology but also the ecosystem. As a result, the Technical Steering Committee (TSC) developed a high-level framework of initial requirements for the release, which have come to fruition with Amsterdam. The requirements include things like modularity; enhancement of model-driven design; the addition of new features/functionalities; open code; upstream collaboration; harmonization with standards bodies; and CI/CD, to name a few.

Architectural principles and and how they funnel into the stack are also critical element of the release. These include:

  • Policy- and Model-Driven: The ability to automate according to intent, without hard-coding
  • Cloud-Native: Built for the cloud and has ability to manage the cloud through native VNF
  • DevOps CI/CD: Built using CI/CD Manage VNFs using CI/CD Break/Fix → Plan/Build

Another key capability of Amsterdam is VNF automation. In current deployments, every VNF works in a different way and can start/stop at various points. Configuring a variety of VNFs is therefore a very time-consuming, manual process. Amsterdam has standardized VNF automation by creating a streamlined deployment process that  happens through the abstraction layer (through the virtual controller) and has a SDK plug-in. More details on automation and CLAMP can be found on the ONAP Developer Wiki, here.

Additionally, ONAP’s focus on automation helps move the industry forward in accelerating the development and deployment of next-gen use cases. Automation is mandatory for 5G deployments due to the scale, access, bandwidth, and latency it demands. Amsterdam provides the platform to deploy new services to enable 5G in an automated manner.


Real-World Support for Amsterdam

Despite ONAP’s infancy, we are proud to see early deployments, testing, and POCs using various modules of pre-release code from member carriers and vendors including Amdocs, AT&T, Bell Canada, China Mobile, China Telecom, Fujitsu, Huawei, Orange, Vodafone and many others. Members have also been testing blueprints of early use cases like VoLTE and residential vCPE. Stay tuned for more information on user stories in the near future!  (To see what members are saying in support of the Amsterdam release, please visit our Member Quotes page here. Additional videos with commentary from members can be found here.)

#OSSummit Recap: Arpit Joshipura meets with theCUBE

By | Blog

Earlier this week Arpit Joshipura, our general manager of networking, talked with John Furrier (@furrier) and Stu Miniman (@stu) at Open Source Summit 2017 in Los Angeles.

In this video Arpit says open source networking is now mainstream among telcos and carriers.

The Linux Foundation is home to 8 of the top 10 open source networking projects. ONAP, one of the most recently launched projects, has already grown to 55 members and more than 1,000 developers contributing to the code. With the addition of Vodafone, more than 55 percent of the 4 .5 billion global subscribers will be influenced by ONAP.

What’s the main driver for growth with orchestration, SDN and NFV? According to Arpit, with 5G and IoT on the horizon, networks better be automated.

In this recent FierceWireless article, Arpit says many of the major carriers already support ONAP. Vodafone joins AT&T, Bell, China Mobile, China Telecom, Jio, and Orange as Platinum ONAP members. Working collaboratively the carriers will be able to deliver new services faster to boost revenue even before 5G hits, according to Arpit.
