Introducing New P4 Compiler, P4 Applications, APIs and Dataplane Debug and Visibility Tools to Accelerate Adoption of Programmable Forwarding Planes

AMSTERDAM, Sept. 25, 2018 (GLOBE NEWSWIRE) -- Open Networking Summit Europe 2018 -- Barefoot Networks, a provider of high-performance and fully-programmable networking solutions, today announced Barefoot P4 Studio, the next generation Software Development Environment (SDE) used to harness the power of Barefoot Tofino™ series of P4-programmable Application Specific Integrated Circuits (ASICs). Barefoot P4 Studio accelerates the adoption of programmable forwarding planes by making it easier to develop, debug and optimize P4 applications and enables smoother integration with the network operating system control and management planes. With Barefoot P4 Studio, users gain the advantage of a robust modular infrastructure, production-ready P4 applications, streamlined set of APIs and powerful dataplane visualization tools.

“With the fast-growing adoption of Tofino in multiple markets, the speed at which our customers are able to develop both standard and new features and deploy them at scale is of paramount importance,” said Craig Barratt, CEO of Barefoot Networks. “With our Barefoot P4 Studio software development environment we are enabling all users of Tofino to seamlessly develop efficient and high quality switch systems that can be used to build scalable and future-proof networks.”

As networks experience greater demand due to ever-increasing traffic and the need to deliver new and differentiated services, Barefoot P4 Studio gives developers the tools necessary to build efficient and scalable network systems. The new offering provides a complete suite of tools including:

  • Barefoot P4 Compiler - drawing upon multiple years of programmable networking experience, Barefoot is introducing the next-generation P4 compiler with dramatically improved compilation speeds, stronger automatic debugging capabilities and support for both P4-14 and P4-16 versions of P4 language. With the P4-16 language introducing a concept of target architectures, a Tofino Native Architecture (TNA) specification is provided to leverage rich capabilities of Barefoot Tofino using P4-16 and support different use-cases.
  • Barefoot Target Simulation Model - software register-accurate model for Barefoot’s current and future ASICs that allows developers to rapidly prototype their P4 applications before deploying them on real hardware.
  • Barefoot P4 Insight™ - dynamic web-based dataplane visualization tool, which gives developers visibility on how their P4 program will be laid out in the hardware and allows them to optimize those programs for maximum scalability and feature density.
  • Barefoot Runtime Interface (BRI) - BRI is a streamlined and P4 program-independent API for enabling communication between control plane and forwarding plane in an extensible and scalable manner. It supports directly configuring all areas of the Barefoot ASIC by control plane or system vendor hardware abstraction layer. In particular, it is a foundation for supporting ONF’s Stratum switch operating system and P4 Runtime.
  • Barefoot Model-driven Abstraction Interface (BMAI) - a new infrastructure empowering developers to create their own higher-level object abstractions of P4 constructs and automatically generate APIs which can be used by the control plane to configure those objects.
  • Barefoot P4 Applications - support for feature rich P4 switch applications written in a modular and reusable fashion and fully integrated with BMAI framework in one package. This integration enables developers to easily extend these P4 applications and have all parts of P4 program to be configured by the same abstraction API.
  • Barefoot Packet Test Framework - Python-based test framework to validate functionality of the P4 applications at all API levels including BRI, BMAI and SAI.
  • Barefoot Unified Device Driver - a single device driver supporting all current and future Barefoot ASICs.

Tofino is the world’s first end-user programmable Ethernet switch ASIC, built using a Protocol Independent Switch Architecture (PISA). Currently in trials with multiple customers, Barefoot P4 Studio is a single SDE supporting all current and future Barefoot ASICs as well as various use-cases that require different ASIC pipeline configurations.
