NeoTap

Industry-leading FPGA timestamping, synchronization and tap aggregation solution.

NeoTap is a tap aggregation and timestamping solution built on the Neo reconfigurable networking platform. It offers precise monitoring while enhancing network performance with industry-leading FPGA-based timestamping and clock synchronization. NeoTap provides ultra-low latency Layer 1 connectivity and flexible software packet processing making it the optimal solution for high-speed, mission-critical environments.

If you are looking for further improvements, our next-gen NeoTap X provides 100G timestamping, optional on-device storage of up to 60 TB and 4x more bandwidth than NeoTap.

Benefits

Ultra-low Latency

NeoTap Layer 1 fabric Hard Wire offers ultra-low latency of just 1.8ns, making it suitable for high-speed environments such as exchanges.

High Timestamp Precision

NeoTap provides industry-standard leading 100ps timestamp accuracy, which is crucial for latency-sensitive applications such as financial trading.

Configurable 10G/25G Support

NeoTap supports both 10G and 25G Layer 1 options, providing future-proof solution for various exchange environments.

Simplified Infrastructure with Enhanced Signal Quality

Eliminate the need for a separate Layer 1 device and optical taps, streamlining network setups, while offering full signal regeneration (retiming), for better signal quality compared to using optical taps.

Detailed Network Troubleshooting

NeoTap includes extensive statistics and troubleshooting software, making it easier to identify and resolve network issues.

Technical Specifications

Timestamping and synchronization

  • Two fixed 40G ports: Dynamically switchable speeds between 10G and 25G on the remaining ports.
  • Advanced PPS synchronization with 1 Mhz and 10 Mhz support – 0 timestamp jitter within a second, when 10 Mhz signal is available.
  • Safran White Rabbit synchronization support: industry-standard implementation from Safran.
  • Fully coherent 10G and 40G timestamps – simpler latency analysis in modern infrastructures that involve market data at multiple speeds.
  • Industry-standard 16-byte Ethernet trailer with EPOC timestamp and extra fields – propagated advanced latency calculation data such as PCS codes and 40G-specific performance fields.
  • FPGA generates up to two VLAN-tagged 100G streams to the backplane or external devices.
  • Once processing on the FPGA is complete, the incoming packets can optionally be VLAN-tagged with timestamped Ethernet trailers, before being aggregated into up to two streams of 100G per second each.

NeoTap Editions

NeoTap Standard

  • 16-core 3.7 GHz AMD EPYC Milan CPU for standard configuration
  • Up to 256 GB RAM for ultra-deep packet buffers
  • One or two PCIe 4.0 x16 100G NICs for up to 400G backplane
  • Multiple NIC options: Intel E810, Mellanox Connect-X6, etc.
  • Simple VLAN interface mode: work with front panel ports using standard Linux tools: ping, tcpdump, etc.
  • DPDK-based high-performance packet routing utility from LDA: receive data from front panel ports, aggregate and rebroadcast through another port. Source code available for custom modifications: compression, packet manipulation, etc.
  • Third-party tools and libraries supported out of the box: all standard Linux and NIC drivers used.

NeoTap Basic

The NeoTap Basic ingests data which is delivered to an external capture system. This is the most cost-effective option for firms which have already invested in a packet capture and processing infrastructure.

  • 2x 100G streams delivered to external infrastructure directly from the FPGA
  • Cost-efficient CPU, only for configuration
  • No ability to rebroadcast through front panel ports
  • Only 100G is supported for the FPGA's output data streams.
