Napatech zero packet loss technology boosts data throughput


ANDOVER, Massachusetts, July 2009 (Eskenzi PR) – Napatech today extended its range of In-line adapters to support 1 Gbps networks. The NT4E In-line and NT4E-STD In-line adapters provide full line-rate throughput at 1 Gbps with zero packet loss, no matter the packet size. This allows vendors of network appliances, such as Intrusion Prevention Systems (IPS) or WAN Optimization solutions, to build high performance products based on cost-effective, standard server platforms.

“This is not just a question of introducing new, more advanced network adapters. The NT4E and NT4E-STD change the rules of the game. It is no longer necessary to build proprietary hardware to achieve high performance. Cost-effective standard servers can be used with the NT4E and NT4E-STD providing the data processing horsepower and throughput to guarantee that all traffic can be analyzed at full line-rate, in real-time”, said Erik Norup, President Napatech Inc.

“We are witnessing a transition from 1 Gbps to 10 Gbps networks. But this does not mean that 1 Gbps is no longer interesting; quite the contrary. There will still be a need for in-line network appliances that monitor, analyze and secure the 1 Gbps links into 10 Gbps networks. One can expect that these links will be fully utilized requiring full 1 Gbps line-rate performance. In this regard, Napatech’s 1 Gbps network adapters are highly relevant”, said Roy Illsley, senior research analyst, Butler Group.

The NT4E In-line and NT4E-STD In-line adapters are ideal for OEM network appliance vendors in the network performance monitoring, network test, network security, financial trading and policy enforcement markets, especially those, which require full 1 Gbps throughput. The NT4E-STD In-line adapter provides a cost-effective solution for customers who require accurate time-stamping and full line-rate reception and transmission of 1 Gbps data traffic with zero packet loss. The NT4E In-line adapter extends these features with advanced protocol and flow recognition, filtering and intelligent distribution of traffic processing on up to 32 CPU cores. An extensive software suite is provided for ease of integration supporting Linux, FreeBSD and Windows.

Napatech is a leading OEM supplier of multi-port 10 GbE and multi-port 1 GbE intelligent real-time network analysis adapters. Napatech adapters provide full line-rate, real-time throughput with zero packet loss no matter the packet size. Intelligent features enable off-load of data traffic processing and packet analysis traditionally implemented in software or proprietary hardware. Napatech has sales, marketing and R&D offices in Mountain View, California, Andover, Massachusetts, and Copenhagen, Denmark. For more information visit
