  • News announced via LFN governing board member, Koby Atival, during ONE Summit keynote
  • Fully open-sourced, L3AF enables Kernel Function as a Service by providing complete lifecycle management of eBPF networking application programs
  • The project brings a strong existing ecosystem, with support from Microsoft, Wipro, Tech Mahindra, and more

SAN FRANCISCO, October 11, 2021LF Networking (LFN), which facilitates collaboration and operational excellence across open source networking projects, today announced that Walmart has moved its L3AF project to the Linux Foundation. L3AF provides complete life-cycle management of eBPF networking application programs with the help of an advanced control plane, offering a cloud and vendor-agnostic platform for launching and managing eBPF programs.

Koby Avital, executive vice president, Walmart Global Tech, announced the news during his keynote address, “Open Innovation Driving Retail Transformation” as part of Open Networking and Edge (ONE) Summit + Kubernetes on Edge Day, this morning.

“I’m excited to open source L3AF, a platform that has allowed us to operate various security and network functions in this omni environment,” said Koby Avital, Executive Vice President, Walmart Global Tech. “With L3AF life cycle management, we’ve been able to tap into the power of eBPF while accelerating and streamlining its usage. This has allowed us to replace third party and Cloud provider-specific solutions with a common platform that’s not only much easier to manage but also more cost effective. By sharing this capability with the community, we hope to help accelerate the development of solutions for managing an omni environment for other enterprises or service providers and bring about standards and practices that benefit everyone.”

“L3AF as a network application for large-scale enterprise complements the eBPF Foundation and other accelerated forwarding and data plane projects under LF networking quite well,” said Arpit Joshipura, general manager, Networking, Edge and IoT, the Linux Foundation. “We’re looking forward to building an open source networking community within this critical application space.”

L3AF is an open source project, developed by Walmart, housing cutting-edge solutions in the realm of eBPF (a revolutionary technology that allows us to run sandboxed programs in an operating system kernel) that provides complete life-cycle management of eBPF programs with the help of an advanced control plane that has been written in Golang. The  control plane orchestrates and composes independent eBPF programs across the network infrastructure to solve crucial business problems. L3AF’s eBPF programs include load-balancing, rate limiting, traffic mirroring, flow exporter, packet manipulation, performance tuning, and many more.

“Lifecycle management of eBPF programs is an exciting area of innovation that will enable new scenarios and use cases,” said Krishna Ganugapati, VP of Software Engineering, Microsoft.  “We look forward to collaborating with Walmart and the L3AF project.”

Tech Mahindra

As a founding member of the L3AF project, we are pleased to see the community join Linux Foundation Networking as a neutral venue for open collaboration,” Manish Mangal, Global Business Head – Network Services, Tech Mahindra. “The collective work being done in L3AF to provide eBPF- based networking and observability solutions in an open format is aligned with Tech Mahindra’s mission to unlock the value of 5G and Networks by helping Enterprises and CSPs transform to Cloud Native Software Centric Digital Operators. We are eager to see the work progress even further.” 


“Walmart is making a significant technology contribution in open sourcing the L3AF platform, enabling production-tested secure kernel-level networking functionality required by the edge computing ecosystem. Open sourcing L3AF under the Linux Foundation umbrella will provide the support necessary for increased pace of innovation and industry adoption,” said Andrew Aitken, General Manager, Open Source Leader, Office of CTO, Wipro Limited.
