Napatech Announces New Set for Network Adapters

By DE Editors

Napatech (Andover, MA) announced ANAHEIM,  the latest release for its NT family of 10GbE high-performance network adapters for PCI-Express. ANAHEIM adds features to its earlier TUCSON software release:  deduplication, filter priorities, packet coloring, and daisychain time synchronization of Napatech adapters.

The new Deduplication feature can remove duplicate frames (frames containing identical payload) from the traffic captured by the Napatech adapter. This saves a substantial amount of server CPU cycles and, for applications storing the network data to disk, also large amounts of disk space.

The new Filter Priorities extend the possibilities of the 64 programmable hardware filters by enabling full control filters working on overlapping definitions. The high performance adapters include features such as line rate capture and processing of frames up to 20Gbps, 10ns time-stamping of every packet, channel merging, frame classification, conditional dynamic frame slicing, support for 32 CPU cores, and more. The feature set supports Linux, FreeBSD and Windows, and includes a programming interface and development tools.

Napatech is seeing more OEMs using several adapters in one server or in servers next to each other, so several Napatech adapters can now be daisy-chained and time-synchronized without using external boxes. In this way, an inter-adapter time-stamping precision better than 30ns can be obtained.
