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 […]
Posted by P4.org on September 25, 2015 Quicklinks : INT Specification – INT GitHub repository – INT demo video Compute virtualization and the widespread deployment of virtual machines has led to an extension of the network into the hypervisor. Network virtualization solutions have emerged that enable rapid provisioning of network services — logical switches, logical routers, load balancers, […]

We have some big news to share about our development of an open SDN software distribution. ONF has been hard at work for the last couple of months, focused on giving end users a clear migration path to open SDN and leveraging open source software to lower the barrier to adoption. We’d like to introduce […]
ONF Atrium Eases Entry to Open Source SDN Adoption; Solves Critical Integration Challenges Facing Today’s Network Operators PALO ALTO, Calif., June 9, 2015 – The Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open Software-Defined Networking (SDN), today announced the release of Atrium, an open SDN software distribution. Atrium is […]
First things first: Welcome to P4.org, 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 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 […]
ONF OpenFlow® Conformant: Certified Product List The OpenFlow® Conformant Product registry provides a real time list ensuring that the following products demonstrate conformance to the OpenFlow® specifications. The OpenFlow® specification is the first Software-Defined Networking (SDN) standard and a vital element of an open software-defined network architecture. All conformance testing is performed by independent, accredited […]
On September 16, 2014, in the opening keynote address at the ONF Member Workday, Nick McKeown (Stanford University professor and ONF Board Member) presented on the subject of Protocol Independent Forwarding, and also described the P4 language. The video with embedded slides is perhaps the best way of understanding the innovative ways that network programming is […]
Protocol Independent Forwarding Background OpenFlow® was originally designed to find a balance between the relatively-fixed functionality of the fastest switching ASICs and the need to encourage ASIC vendors to produce more flexible chips that software can program. The OpenFlow® 1.3 specification (with TTPs) provides a good abstraction for more fixed-function devices. This whitepaper came about […]
