| 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). write your comments about the article :: © 2010 Computing News :: home page |
