The World’s First 40G Network Analysis Adapter

23-Feb-2012

Napatech offers the world’s first 40 Gbps Ethernet adapter for network monitoring and analysis. The NT40E2-1 Capture Adapter is a high-performance 1 x 40 Gbps intelligent PCIe Gen2 network analysis adapter for Capture & Replay applications. The NT40E2-1 intelligent network adapter provides a single QSFP+ 40 GbE port and can be used for both packet capture and transmission.

Designed for Off-the-Shelf Standard Servers
The NT40E2-1 Capture Adapter is based on a low-profile hardware design and can be installed in almost any standard server.

High-Speed Packet Capture and Transmit
The NT40E2-1 is based on a PCIe Gen2 interface with 25 Gbps bus capacity. Nevertheless, 40 Gbps packet capture at full line-rate is possible in burst situations ensuring zero packet loss. Packet transmission up to the PCIe bus limit is possible allowing 2 x NT40E2-1 network adapters to be used in In-Line applications.

Intelligent flow identification, filtering and distribution
Intelligent features for frame decoding, flow idenfiication, flow filtering and distribution to 32 CPU cores allow the NT40E2-1 to off-load and accelerate customer applications.

Plug-and-Play Capability
The NT40E2-1 supports the same API, feature set and capabilities as existing Napatech 10 Gbps network adapters allowing OEM customers to support 40G on a plug-and-play basis.

Precise Time Stamp
The NT40E2-1 Capture supports 10 ns time-stamping of both captured and transmitted frames. Timing can be synchronized to GPS, CDMA or IEEE 1588v2/PTP. An external SMA time synchronization connector is complemented by two internal time synchronization connectors allowing daisy-chain distribution of timing signals.

Capture and Replay Features

  • 40 Gbps packet capture and transmit with zero packet loss
  • Zero-copy DMA transfer to host memory with cache-hit optimization
