n2disk™

100 Gbit network traffic recorder with on-the-fly indexing

n2disk™ is a network traffic recorder application capable of capturing full-sized network packets up to 100 Gbit from a live network interface, and write them into files without any packet loss. n2disk™ has been designed to write files into disks for very long periods. When n2disk™ reaches the maximum configured data retention (disk space), it will start recycling the files from the oldest one.

n2disk™ uses the industry standard PCAP file format to dump packets into files so the resulting output can be easily integrated with existing third party or even open-source analysis tools (e.g. Wireshark).

NetFlow technologies are more manageable and require less disk space to be stored, but in some cases, like DPI analysis, troubleshooting, or controlled traffic replay, it is not useful.

n2disk™ can be effectively used to perform numerous activities, among these:

  • Off-line network packets analysis by feeding a specialized tools like IDSs
  • Reconstruct particular communication flows or network activities
  • Reproduce the previous captured traffic on a different network interface

Ideal for Every Environment

Use Cases

Troubleshooting

n2disk enables continuous packet capture with zero packet loss, providing a reliable record of all network activity. When issues arise (such as service disruptions, dropped connections, or abnormal latency) engineers can quickly rewind network traffic and pinpoint root causes with full-packet visibility.

In security-sensitive environments, having a searchable, time-stamped archive of packet data is critical. n2disk supports long-term retention and indexed search capabilities, making it an ideal solution for forensic investigations, regulatory audits, and lawful interception scenarios.

In ultra-low latency environments like High-Frequency Trading, every microsecond matters. n2disk, when used with PF_RING and hardware timestamping, allows precise capture and analysis of packet timing and jitter. This helps trading firms validate performance, troubleshoot delays, and optimize infrastructure for maximum speed and accuracy.
