Napatech Intros NT20E2 Capture and NT20E2 In-line Adapters

Napatech announced the world's first 2x10 Gbps Intelligent Real-time Network Analysis adapters based on PCI-Express Gen 2 with the introduction of the NT20E2 Capture adapter and NT20E2 In-line adapter products. The NT20E2 In-line is ideal for applications that require both capture and transmit in real-time, such as Intrusion Prevention Systems (IPS) and Policy Enforcement applications operating at 10 Gbps line-speed. This is complemented by the NT20E2 Capture adapter, which provides full 20 Gbps packet capture throughput over the PCI-Express Gen 2 bus.

The NT20E2 Capture and In-line adapters provide an impressive list of features for pre-processing, off-loading and accelerating network appliance performance. Both products are based on a low-profile form factor with SFP+ modules and PCI-Express Gen 2.

Key features for the NT20E2 Capture adapter include:
- Full throughput 20 Gbps capture and analysis;
- Zero packet loss no matter the packet size;
- Near-zero server CPU load;
- 10ns precision time-stamping of received packets;
- Hardware time synchronization based on GPS, IEEE1588v2 or CDMA;
- Merging, dynamic slicing and de-duplication of traffic;
- Advanced packet classification with intelligent identification of flows;
- Flow filtering and intelligent distribution to up to 32 CPU cores;
- Zero-copy DMA transfer to host memory with cache-hit optimization;
- Ethernet, TCP and UDP checksum verification;
- Supports libPCAP and PCAP applications (e.g. SNORT).

Key features for the NT20E2 In-line adapter include:
- Full throughput 20 Gbps capture, analysis and re-transmission;
- Zero packet loss no matter the packet size;
- Near-zero server CPU load;
- Advanced packet classification with intelligent identification of flows;
- Flow filtering and intelligent distribution to up to 32 CPU cores;
- Zero-copy DMA transfer to host memory with cache-hit optimization;
- Ethernet, TCP and UDP checksum verification and generation;
- Transmit of packets according to individual packet time stamps;
- Configurable Inter-Frame Gap (IFG);
- 10ns precision time-stamping of transmitted packets;
- Supports libPCAP and PCAP applications (e.g. SNORT).
