Traffic Recording

With increasing network complexity, it becomes necessary to store the content of network communication in order to guarantee that the services they are providing are flawless. In order to pass audits they need to collect all their traffic to prove there is no wrongdoing, banks have to fulfil many regulations as they are handling money of all of us. Telco’s in many countries are obliged by law to perform data retention as a form of evidence collection. Network security solution vendors need to offer the option of offline traffic analysis and offline troubleshooting.


The amount of data on today’s high-speed networks presents a great challenge for traffic recording. There are two main issues: throughput of disk subsystems does not scale with throughput of computer networks and storage capacity of today’s disks is not sufficient to store all the data running through the network. However, it is not necessary to store all the data, for instance huge data flows of videos from Netflix or Youtube that are uninteresting from a security point of view. This problem can be circumvented by filtering this type of traffic in hardware through FPGA network cards that let only the traffic of interest to be stored on HDD.

Netcope Packet Capture and Netcope Session Filter are high-performance FPGA network cards with added intelligence perfectly suited for traffic filtering at wire-speed. With these products, it is possible to preset a number of filtering rules for both Rx and Tx traffic based on input network interface and L3 and L4 header fields, distribution of incoming traffic over multiple DMA channels, cropping of incoming frames before forwarding them to SW with configurable length in each filtering rule, or forwarding and duplication of incoming frames to an output network interface and a DMA channel.

Netcope Products Offer:

  • Ready-to-use firmwares

    • Wire-speed packet processing

    • Stateless/stateful hardware filters (NPC/NSF)

    • Extraction of NetFlow/IPFIX data in hardware (NPC, NSF)

Netcope Success Stories


NSF-100G2-Picomass-Netcope Network Traffic Monitoring

Picomass uses Netcope Session Filter in the IPS200 DPI solution because NSF is capable of offloading traffic to hardware. This makes real-time DPI on 100G networks possible.

Flowmon Networks

Flowmon Networks Network Traffic Monitoring

Flowmon Networks aims to develop a new generation of NetFlow/IPFIX probes that can monitor and process traffic of 100GE high-speed networks. Because of that, Flowmon Networks needs to find a network card that would be able of handling 100 GE monitoring requirements.
