On August 8th, 2017 Luca Deri the founder of ntop was kind enough to call in and discuss Network Performance Monitoring (NPM). Luca is a well-recognized leader in the field of NPM having started at IBM Research back in 1993. He then went on to launch ntop in 1997 and has never looked back. In this specific market PF_Ring, n2Disk and several other tools by Luca and his team have become the de facto standard by which all others are compared. Today we discussed NPM then and now, touching on the abuse of port 80 for a wide range of wrapped traffic. We then moved on to packet capture, and the need for smart NICs moving forward if we wish to keep pace with faster networks like 50 and 100GbE.
