Supporting 64 bit ARM platforms is important because there is now a plethora of inexpensive boards based on this architecture. Thanks to the use of docker containers, several manufacturers allow their devices to take advantage of this technology to run third-party software on devices that used to be not extensible. Here you can read how […]
How To Analyse Asymmetric VLAN Traffic
A VLAN is a method for partitioning a layer two broadcast domain creating virtual networks of homogeneous systems hence promoting network segmentation. A ethernet port with no VLAN tag is called access port, whereas a switch port with VLAN-tagged packets is called tagged or trunk port. End systems are usually connected to access ports meaning […]
How Flow-Based Traffic Classification Works
Many ntop products such as ntopng, nProbe, and PF_RING FT just to name a few are based on network flows. However not all our users know in detail what is a network flow, and how it works in practice. This blog post describes what they are and how they work in practice. What is a […]
Going Beyond 5-Tuple in Network Flow Analysis
Traditionally flow-based tools are based on the 5-tuple attributes (source and destination IP, source and destination port and the protocol field). Often they are complemented with additional attributes such as VLAN or Tunnel Id in order to avoid mixing in the same flow packets that belong to different communications. The above picture shows the 5-tuple […]

How to Keep your Infrastructure Healthy with ntopng
Almost 3 years ago we introduced Active Monitoring support in ntopng. This allows you to monitor the infrastructure and make sure that all systems are operational. In fact ntopng can continuously monitor hosts in your network by periodically running different active measurements including: ICMP, which measures the RTT (Round Trip Time). Continuous ICMP, which evaluates network reachability […]
