Napatech Announces 4×1 Gbps In-line Network Adapter with Bypass

(Ping! Zine Web Hosting Magazine) – Napatech today announced the availability of a new 4×1 Gbps In-line network adapter with bypass functionality for high performance Intrusion Prevention System (IPS) applications. Designed for use in off-the-shelf standard servers, the NT4E2-4T-BP provides comprehensive bypass functionality for assurance of in-line connections while also providing intelligent flow identification and distribution to up to 32 server CPU cores. This allows IPS applications to improve throughput performance on a per CPU core basis while assured that every packet can be examined at full load.

The NT4E2-4T-BP provides 4 electrical RJ45 Ethernet ports supporting port speeds from 10 Mbps to 1 Gbps. Non-latched bypass functionality is provided for port pairs ensuring that connectivity is maintained in the event of power failure, system breakdown or software failure. The bypass functionality can be configured as fail-open or fail-closed allowing the NT4E2-4T-BP to be configured in normal, bypass or disconnect modes at startup and shutdown.

In addition, bypass can be initiated on command via the software Application Programming Interface (API) using watchdog timer functionality that allows software programmable time-out intervals to be configured. Local power is provided on-board ensuring that bypass can be performed within 10 ms even in the event of power failure.

The NT4E2-4T-BP provides the same comprehensive feature set as existing 20 Gbps and 40 Gbps Napatech In-line network adapters including guaranteed zero packet loss, flow identification, filtering and distribution to up to 32 server CPU cores. Designed for standard off-the-shelf servers, the NT4E2-4T-BP enables OEM vendors of Intrusion Prevention Systems to build a high performance IPS using off-the-shelf hardware reducing risk, time-to-market and total cost of ownership.

“All our OEM vendors are focused on improving efficiency, performance and cost and our IPS vendor customers are no different”, stated Henrik Brill Jensen, CEO Napatech. “Adoption of standard servers as a hardware platform provides a cost-effective, high performance alternative to in-house development. With the strong roadmap of server CPU chipsets providing an annual 60% improvement in processing performance, this approach is quickly becoming the de-facto choice for vendors of network security appliances. Using Napatech In-line network adapters, OEM vendors ensure that they are taking maximum advantage of standard server platforms while accelerating throughput performance.”
