High Performance Multi-function Programmable Platforms

The Arista 7170 Series of programmable switches combine high performance with a fully programmable pipeline for a range of flexible solutions at both the spine and leaf tiers. The 7170 Series allow the data plane to be customized using EOS and P4 profiles to address multiple use-cases for Cloud, Enterprise, Service Provider and Content Networks.

The 7170 Series with Arista EOS support a rich set of both data plane and control plane features. Advanced features are enabled through profiles, that add features, new header formats, adjust resource scale, alter the order of operations or change the types of lookups performed on traffic passing through the switch. This level of flexibility means that not only is the 7170 Series a high performance data center switch, it can be used for a wide variety of new applications where traditionally appliances or expensive proprietary routers were required.

Based on the Barefoot Tofino switch chip, the Arista 7170 Series delivers fully programmable systems for a range of applications for network security, application telemetry, offloading hypervisors and flexible routing with custom encapsulations and new protocols.
