Electronic Trading

Arista's Layer 1 and FPGA-based switching platforms address the full latency range of electronic trading infrastructure, from the sub-200 ns Layer 2 switching of the 7132LB and 7135LB series to the programmable Layer 1 replication and fan-out of the 7130 platform family with fan-out latencies as low as single-digit nanoseconds. These platforms are purpose-built for exchange connectivity, market data distribution, and high-frequency trading environments where each nanosecond of avoidable latency represents measurable execution risk.

The 7130 series Layer 1 FPGA switch operates below the software processing layer, forwarding market data feeds at the speed of electrical or optical signal propagation through the device. This makes it the right platform for passive fan-out architectures where a single exchange market data feed must be replicated to many trading strategy servers simultaneously, with each replica receiving an identical and identically timed copy. The 7132LB and 7135LB extend the portfolio with FPGA-based Layer 2 and Layer 2+ switching at 25G speeds, adding IP routing and PTP timing while maintaining sub-200 ns latency for exchange gateway and order management connectivity.

Arista EOS runs across both the 7130 and 7132/7135 platform families, enabling consistent management, telemetry, and automation from CloudVision regardless of whether a port is operating at Layer 1, Layer 2, or Layer 3. PTP (IEEE 1588v2) precision timing integration supports the timestamping accuracy required by regulatory reporting frameworks and co-location facility timing infrastructure that trading firms depend on for best-execution documentation and market surveillance compliance.
