Intel® Programmable Ethernet Switch Products
Build customizable, ultrafast networks to meet your unique infrastructure needs and deliver differentiated solutions to your customers.
As data growth accelerates and demanding new workloads become mission critical, our customers need their networks to work harder. With Intel® Programmable Ethernet Switch Products, you can create ultrafast networks that are fully customized to your needs. This portfolio eliminates bottlenecks and can transform even the largest data center into a focused, balanced, and optimized high performance computer unto itself.
The products spotlighted here are from the Intel acquisition of Barefoot Networks in June 2019. The move helps Intel meet the performance and ever-changing needs of network owners, while supporting the company’s focus on end-to-end networking and infrastructure leadership.
Intel® Tofino™ Series
Meet the skyrocketing demand for bandwidth and data availability with the world’s fastest P4-programmable Ethernet switch ASICs.
Intel® Tofino™
Intel® Tofino™ is the world’s first end-user programmable Ethernet switch. It is built using a Protocol Independent Switch Architecture (PISA) and is P4-programmable. Intel® Tofino™ switches are available in a selection of SKUs to suit different applications and needs.
Intel® Tofino™ 2
The next generation of programmable Ethernet switch, Intel® Tofino™ 2 is the best choice for meeting the needs of hyperscale data centers.
Built with the same architecture as Intel® Tofino™, it’s capable of delivering twice the bandwidth of its predecessor—up to 12.8 Tb/s.
Intel® P4 Suite
Access a complete set of tools, APIs, and more to develop and optimize P4 software for Intel® Programmable Ethernet Switch products. P4 is the only open source language designed for programmable packet processing devices.
Intel® P4 Studio
In a next-generation development environment, Intel® P4 Studio gives you a use case‒driven toolset that includes all the resources you need to quickly develop custom P4 software for Intel® Tofino™ Programmable Ethernet Switches. It’s flexible and hardened for multiple control-plane options and offers helpful production-ready data-plane implementations.
Intel® P4 Insight
Reduce the development time for networking solutions and fully optimize your network software with Intel® P4 Insight. This software provides powerful debugging tools and gives you a detailed dashboard view of your P4 program so you can see exactly how it’s mapped to hardware resources.
Intel® Deep Insight Network Analytics Software
Intel® Deep Insight Network Analytics Software enables real-time per-packet visibility into your network infrastructure. Monitor and analyze every packet drop. Detect and store anomalies and events for deeper historical analysis.
Highlighted Use Cases
Real-Time Network Telemetry
Collect end-to-end data on your network state in real time to monitor issues—including short-lived events—that cause data bottlenecks and network failures. This will allow your enterprise to fix configuration errors and optimize data routing to greatly improve network performance.
Layer 4 Load Balancer
Load-balancing efforts often need complex appliances that can be a burden on the network infrastructure. With Intel® Tofino™ and Intel® P4 programmability, load balancing can be done inside the switch, bridging the gap between multiterabit switches and gigabit servers and appliances.
In-Network DDoS Detection
Intel® Tofino™ Programmable Ethernet Switches can enable networks that detect DDoS attacks faster and mitigate them more effectively due to their exceptionally high performance, and because these tasks are performed in the network and don’t rely on other resources.
Additional Use Cases
- DNS caching
- Firewall
- Network packet broker
- Tunnel gateways

FAQs
Frequently Asked Questions
No. ASIC cost is determined by die size. The Intel® Tofino™ die size is similar to the die of legacy fixed-function ASICs running at the same speed.
No. In fact, in many cases they consume less. For equivalent features and protocols, the power consumption is identical. In a programmable switch, you can turn off features you don’t need and reduce power or use smaller tables.
No. With Intel® Tofino™ and Intel® Tofino™ 2, we have shown that programmability does not come with a compromise on performance. Intel® Tofino™ and Intel® Tofino™ 2 can be fully programmed by users, using the P4 programming language, and can currently process up to 12.8 Tb/s.
P4 is an Apache-licensed open source language owned by P4.org, an independent nonprofit. Any company, university, or individual can join P4.org free and contribute to the language, compiler, and tools. Intel is one of over 100 members of P4.org, including companies from all across our industry, from AT&T to ZTE, and some of the world’s top universities. The P4.org Advisory Board consists of Amin Vahdat (Google), Jennifer Rexford (Princeton), Nate Foster (Cornell), Guru Parulkar (ONF), and Nick McKeown (Stanford/Intel). The language was designed by world experts in programming language design from Princeton, Cornell, Stanford, VMware, Intel, Microsoft, Xilinx, Barefoot, and Google. P4 is open source and owned by everyone. The language is carefully designed to be target independent and can be used to program any programmable forwarding device. So far, it has been used to program a variety of software and hardware switches and NICs from different sources. See P4.org for more details.
P4 is more general than OpenFlow, allowing users to define exactly how the forwarding plane processes packets. OpenFlow can be expressed in the P4 language; openflow.p4 provides a helpful way to get started.
This is a very valid question for a switch that is based on a fixed-function ASIC. Intel® Tofino™ is highly programmable, consisting of multiple pipelines and Match Action Units (MAU) inside each pipeline. An MAU contains a flexible parsing logic and multiple SRAM and TCAM table blocks that can be carved to accommodate a specific deployment. Intel can provide sample verified scalability numbers based on a reference P4 program and under NDA. However, they should never be interpreted as maximum theoretical scalability values of the chip.
Programmability enables limitless flexibility and multiple use cases, ranging from the customization of the switch table sizes for efficient scale to the enhancement of the existing networking functions and the addition of new capabilities such as telemetry, security, and load balancing.
Absolutely! You should ask your vendor about their support for Intel® Tofino™ in their switching platform. Once the Intel® Tofino™-based platform is offered, you should be in full power to make data-plane feature requests and expect a feature delivery road map on the existing ASIC.
