How Great Hashing Can (More Than) Double Application Performance
Most ntop applications (ntopng, nProbe, Cento) and libraries (FT) are based on the concept of flow processing, that merely means keeping track of all network communications. In order to implement this, network packets are decoded and, based on a “key” … Continue reading
How to Dump, Index, and Layer-7 Filter Network Traffic at High Speed
n2disk is an application that many of the ntop community uses to dump traffic up to 100 Gbit. What few people know is that n2disk can index data not just using packet header information (i.e. IP, port. VLAN, MAC…) but … Continue reading
Monitoring Industrial IoT/Scada Traffic with nDPI and ntopng
Monitoring Industrial IoT and SCADA traffic can be challenging as most open source monitoring tools are designed for Internet protocols. As this is becoming a hot topic with companies automating production lines, we have decided to enhance ntop tools to … Continue reading
