QUIC, What’s That?

As you may know, I do ntopng consulting, and support companies in their implementation of ntop solutions. For some time now, ntopng users have noticed a high amount of QUIC traffic in their respective networks. Most people don’t really know what QUIC is, which is why I’d like to take this as an opportunity to…

Into the Flows: Collecting Data with nProbe and nTop

The role of these two components is pretty clear: nProbe has the role of collecting traffic data, while nTop makes that data visible and easily analyzable. There is something, however, that needs to be explicitly stated, which is to decide whether it’s ntopng that should contact nProbe or vice versa, and as we’re in a…

nTop and nDPI: How to Increase Network Traffic Analysis

nTop now uses the nDPI (network deep packet inspection) library to classify packets within network traffic for those protocols that either do not use a standard port (defined as well known ports like and or that are dynamically assigned. In any case the need to classify not only the packet header but also…

nBox to NetEye Elastic Module

A customer asked me to analyze their network flows, with a solution oriented towards using an nBox that collects NetFlow data from a router located away from the branch office, takes it in for analysis, and then sends it to a NetEye Elastic module, which act as an analysis console for that NetFlow data. The…

Distributed, Multi-Instance nProbe: NetFlow Analysis

A client with a really large number of routers installed at their client asked me one day to analyze each of those network flows. They hoped that an analysis tool would be able to discover and impose a multitenant configuration all on its own, so that access could be granted to final users while guaranteeing…

nProbe and nTop All-in-One (Single Node): Netflows Analysis

One of my clients with a number of routers installed at their own remote location asked me if I could analyze the network flows at multiple locations. Their network architecture is a full mesh, and thus has private subnetworks, data center environments, and even in some cases cloud providers. Complex architectures like this require increasing…

Chi si sta mangiando la banda? Scoprilo con ntopng

Chi riesce a sapere veramente quali sono i protocolli utilizzati nella rete locale? Solitamente con i netflow si può distinguere il traffico attraverso le porte L4 (80=http,443=https,..) ma non è più sufficiente. Alcune applicazioni usano invece porte dinamiche (vedi nfs, ftp, routed sap, …), altre le porte stesse, come si può allora essere in grado…
