LF Networking (LFN) represents the largest set of networking projects with the broadest community in the industry that collaborate on the many challenges and opportunities in the open source networking stack. Since forming in January 2018, it has grown to over 100 members that represent ~70% of the world’s mobile subscribers. Network operators like AT&T, China Mobile, China Telecom, and Orange are deeply engaged in the technical work of the community, and some of that innovation will be on display at the LF Networking booth at ONS Europe, Sept 23 – 25, 2019 in Antwerp, Belgium.

The ONS Europe CFP collected a record number of submissions this year for speaking as well as for community-driven demos. Accordingly, we’ve expanded the number of demo stations from 10 to 12 and highlight innovations from 7 of the 8 LFN projects from within the LF Networking umbrella (FD.io, ONAP, OPNFV, OpenDaylight, OpenSwitch, PNDA, and Tungsten Fabric), as well as projects from adjacent technology stacks, including Collectd, DPDK, HAPROXY, Helm, Kafka, Kubernetes, Openstack, OpenWRT, and Prometheus. We welcome you to spend some time talking to and learning from these experts in the technical community during the Technical Showcase in the Atrium Monday – Wednesday.

For the first time, the LFN Booth will feature the demo “OPNFV Verification Program (OVP) in Action” where visitors can learn about the three verification tracks—NFVI, VNFs based on requirements from the ONAP community, and test labs. Through OVP, CSPs can accelerate time to deployment for new network services, improve interoperability and software quality, and reduce in-house testing and costs, while vendors improve time to revenue for new product offerings, achieve greater alignment with customer requirements, and demonstrate product quality.

Listed below is the full networking demo lineup, and you can read detailed descriptions of each demo here.

The past month and a half we have been putting CompuLab's Airtop 3 computer through some demanding benchmarks and a variety of endurance workloads. With the Airtop 3 under test loaded with an 8-core / 16-thread Xeon processor, NVIDIA Quadro RTX 4000 graphics, and 64GB of RAM with NVMe SSD storage there were some concerns over thermal throttling and if this fan-less industrial PC design could really deal with the generated heat. But after all of this testing, the Airtop 3 continues running strong and another shining example of CompuLab's engineering strength.

Guest Post By Kelsey Skunberg, Linux Kernel Mentorship Program Mentee

 

My name is Kelsey Skunberg and I am starting my senior year for my Undergraduate in Computer Science at Colorado State University. This summer, I had the honor of participating in the Linux Kernel Mentorship Program through CommunityBridge. Throughout the mentorship, I grew very fond of working on open source projects, learned to work with the open source communities, and my confidence as a developer has grown tremendously.

Since the beginning, I found the Linux kernel community to be very welcoming and willing to help. Many of the developers and maintainers have taken time to answer questions, review patches, and provide advice. I’ve come to learn contributing is not quite as scary as I first anticipated. It’s ok to make mistakes, just be open to learning and new ideas. There are a lot of resources for learning, and developers willing to invest time in mentoring and helping new contributors.

Before learning of the Linux Kernel Mentorship Program, I was interested in learning how to contribute to the Linux kernel, but didn’t know how and where to start. The application process alone helped me learn the basics of Linux kernel development, how to get started contributing, and more importantly how to work with the kernel community.

The application process gave me the foundation needed to contribute to the Linux kernel by teaching me how to build patches, debug, complete boot tests, and start working with open source communities. I was able to grow these new skills throughout the mentorship program while working on my selected project.

I chose to work on PCI Utilities and Linux PCI with Bjorn Helgaas as my mentor. Bjorn has been an incredible mentor who provided me with a great amount of advice and has introduced me to several tools which make the development process easier.

My project has consisted of multiple tasks that helped clean up code, and enhance existing PCI features.

I enhanced lspci to:

• Decode AIDA64 log files (Started by Bjorn Helgaas)
• Decode earlydump output (Started by Bjorn Helgaas)

I restructured and improved lspci and Linux PCI code by:

• Finding and removing unused code (functions, API)
• Moving functions to better locations
• Improved logic to improve maintainability of Linux PCI code paths

I’ve been able to study how PCI works, learn how to navigate the kernel tree, and gained a lot of experience working with the Linux kernel community to get patches applied successfully.

I am also very thankful for the mentorship program for bringing me to Open Source Summit 2019 in San Diego, where I’ve been able to learn, network, and work on my public speaking. I co-presented with Shuah Khan about my experience as a mentee. View my presentation slides.

Moving forward, I plan to continue contributing to the Linux kernel and being part of the Linux kernel community even after the mentorship ends. I’ve truly enjoyed the past three months and while I continue to learn, I hope I can pass on what knowledge I’ve gained to future mentees and others interested in learning Linux kernel development while I continue to grow myself.

Thank you Shuah and the Linux Foundation for this opportunity. I am thankful to everyone who has helped me get my feet on the ground.
