Not All Servers Are Alike (With DNA) – Part 2
Some time ago, we discussed on the first part of this post, why not all servers spot the same performance with DNA. The conclusion was that beside the CPU, you need a…
BYO10GPR: Build Your Own 10 Gbit Packet Recorder
Packet recorder appliances are one of the last network components that have insane prices. Years ago this was justified by the fact that in order to capture traffic at high speed it…
Monitoring on the MicroCloud
When I started to develop ntop in 1998, it was clear to me that the network was a huge, volatile (or semi-persistent if you wish), constantly changing database. In ntop this database…
10 Gbit (Line Rate) NetFlow Traffic Analysis using nProbe and DNA
In the past couple of years, 10 Gbit networks are gradually replacing multi-1 Gbit links. Traffic analysis is also increasingly demanding as "legacy" NetFlow v5 flows are not enough to network administrators…

SFProbe: Embedding nProbe on an SFP
In 2004 my friend Alex Tudor of Agilent involved ntop on a very challenging project. The idea was to monitor the network from the exact place where packets were originated. In fact…
Packet Monitoring using ntop and Cisco ON100
From time to time, Cisco builds ntop-friendly products. This is the time of the Cisco ON100 network agent. This tiny device that can fit on your hand, has been integrated with ntop…
Precise Interface Merging Without Hardware Timestamps
In network monitoring it is very common to use taps for duplicating network traffic (RX and TX directions). Taps are important as they allow network probes to operate passively without interfering with…
