Why I Network Saurav Das

ONF Principal System Architect, Saurav Das, shares how a Professor got him into networking.   Why am I in networking? There is a simple way to answer that – Professor Nick McKeown. Let me explain. ln a previous life, I spent several years working in the optical communications industry, related to, but not quite the same […]

OSSDN Drives Interoperability

Bithika Khargharia shares an overview of three open source projects from ONF’s With SDN and a disaggregated network stack, interoperability is what enables best-of-breed choice and prevents vendor lock-in when the pieces are aggregated back in the context of use cases and solutions. This week I want to talk about three different ONF […]

Paxos made switch-y

By Huynh Tu Dang, Marco Canini, Fernando Pedone, and Robert Soulé. Paxos is one of the most widely used protocols for solving consensus, the problem of getting a group of participants to reliably agree on some value used for computation. Paxos is used to implement state machine replication, which is the foundation for building fault-tolerant […]

Let’s get started

First things first: Welcome to, the official home of the P4 language, open-source P4 programs, developer tools, compilers and apps. P4 is a declarative language for telling forwarding-plane devices (switches, NICs, firewalls, filters, etc) how to process packets. It’s really cool and we think it’s going to change how networking devices are designed forever. […]

Dan Talayco – Self-Referential Software

 Dan Talayco has been involved with SDN from 2009 when he worked at Stanford in the CleanSlate Lab where the first OpenFlow® standard was defined. He developed early hardware implementations of the protocol. In 2010, he joined Big Switch Networks where he spearheaded the Indigo and Loxi projects. He became the chair of the ONF […]
