Bringing OCP Vision to Reality with Programmable Dataplanes: A Progress ReportArkadiy Shapiro | Mar 12, 2019
It’s that time of the year again when IT professionals descend on San Jose, CA to check on the progress of the OCP community since last year, discuss new technologies and be “open together.” Throughout my personal career, it has been a pleasure to witness the tremendous growth of this community through the size and number of events each year. Open Compute Summit is one of the most important trade shows on Barefoot’s calendar for one simple reason - fully programmable networking dataplanes unlocked by an open programming language are key to the realization of OCP’s vision of open IT infrastructure.
Last year, together with our partners, we made several announcements during the summit:
- Full upstreaming of Barefoot Tofino support for SONiC, in partnership with Microsoft, Edge-core Networks and WNC.
- Partnership with IP Infusion to enable their commercial enterprise-grade network operating system to run on Barefoot Tofino-based switches with full support for Smart Programmable Realtime Inband Network Telemetry (SPRINT) and integration with Barefoot Deep Insight analytics.
Since then, we have been hard at work enhancing already available solutions and bringing announced visions to reality, all while significantly growing our presence in the marketplace with Barefoot Tofino and Barefoot Deep Insight. In addition, the P4 community has grown to over 150 participating organizations with several summits held in the United States, United Kingdom, Korea, Japan and China in 2018. Multiple presentations and demonstrations that involve Tofino, Deep Insight, P4 Studio and P4 will be held this year to show how far we have come.
- SONiC Deployments Powered by Programmable Dataplane
Presenter: Arkadiy Shapiro, Barefoot Networks
Since last year’s announcement, we have kept up with validating every new SONiC release and worked with our ODM partners to expand the set of supported Barefoot-based switches. In addition, we upstreamed support for dataplane telemetry (INT and SPRINT™) and enabled multiple new use-cases such as bare metal server hosting easily inside the same SONiC image. In this presentation, I will present Barefoot’s unique approach to SONiC and explain how programmable data plane has helped to accelerate SONiC adoption in 2018.

- Software Defined Fabric for OCP-based Leaf & Spine Switches
In the fall of 2018, Kaloom was a launch customer for Barefoot P4 Studio and announced their first product. SDF is a next-generation data center fabric solution built from the ground up on a fully P4-programmable data plane inside Tofino-based bare metal switches. This presentation will explore technical details and benefits of SDF as well as touch on the new requirements for the data centers such as slicing, automation, server style management and containerization.

- Uncompromised Dataplane Telemetry on Multi-vendor Cloud fabric with Barefoot Tofino and Barefoot Deep Insight
Partners: IP Infusion, Microsoft
Since last OCP Summit, we have been able to integrate the P4 program that enables Smart Programmable Real-time INT (SPRINT) in two network operating systems: SONiC and IP Infusion OcNOS. SONiC dataplane telemetry feature based on Dtel SAI APIs is fully upstreamed as of SONIC July 2018 release and is also available on IP Infusion OcNOS. For this demonstration, we built a data center fabric and enabled SPRINT capability on Barefoot Tofino-based bare metal switches from different vendors running SONiC and OcNOS. Using this fabric and the Barefoot Deep Insight analytics engine, we will explore how easy it is to identify and root-cause the most challenging network performance scenarios impacting a real application. During the demonstration we will leverage powerful analytics tools, such as path and latency tracking, packet drop analysis, microburst detection and congestion analysis to get full visibility on aggressor and victim flows. Demonstration will analyze the real-time application traffic, all in the data-plane and packet-by-packet, with no synthetic probes or traffic sampling.

- Disaggregated Chassis with SONiC and VxLAN
Partners: Microsoft, Arista Networks
In 2018, Barefoot, Arista Networks and Microsoft used P4 and Tofino to develop a bare metal server hosting use-case. This will be demonstrated with interoperability across multiple ASICs in a data center fabric acting as a disaggregated chassis switch. After looking at this demonstration, one may wonder whether P4-programmable data plane inside Arista 7170 offers anything unique for this scenario that others do not. In fact, today all ASIC and system vendors can support features required here such as Layer 2, Layer 3 and VxLAN tunneling with decent scale. Programmable dataplane helps us repurpose and dedicate all the resources of the ASIC to enable broad adoption of this use case with hundreds of thousands of virtual networks deployed on a cloud infrastructure. After seeing the demonstration in the Microsoft booth, we invite you to visit the Barefoot booth to learn more about how P4, Barefoot Tofino and Tofino 2 offer unmatched value for this use case.

- Network Infrastructure High Availability with SONiC Warm Reboot
As more and more services are consolidated onto the cloud, high availability for infrastructure becomes more critical than ever before. Barefoot Tofino has always been supporting the ability to execute ASIC “restart” without service disruption for many scenarios ranging from SAI upgrade to unplanned crash. In 2017, the SONiC community introduced Fast Reboot capability, which we integrated with Tofino as part of our SONiC support announced in OCP Summit 2018. Back then, we were already able to achieve a dataplane outage of less than 1 second, far exceeding the results from our competition and stated expectations of SONiC Fast Reboot. With the SONiC November 2018 release and Warm Reboot feature, the community completed improvements to SONiC control plane that significantly increased the high availability bar to expect no service disruption. Here at OCP Summit 2019, we are showcasing our support for SONiC Warm Reboot along with Microsoft and other ASIC vendors. After seeing the demonstration at the Microsoft booth, we invite you to visit the Barefoot booth to learn what makes our support for SONiC high availability unique.
Location: Microsoft, Booth A6
Stop by our booth for additional hardware show-cases including switches based on recently announced Tofino 2 ASIC.
We look forward to being open together at OCP Summit 2019!
