This third and final article completes our introduction to ∆Q and the new science of network performance. It follows on from the first and second articles.
The history and philosophy of ∆Q

This is the second in a series of articles introducing ∆Q, the breakthrough new science of network performance. For the first article, click here.
A beginner’s guide to ∆Q
October 26, 2015 By
I would like to offer you a different way of thinking about networks. The ∆Q framework (shortened to “ΔQ”) may be hard to type, but it’s quite easy to understand. As the ‘ideal’ metric, it is also rather useful, since it enables the precision engineering of performance and cost. In this three-part series, we will take a […]
Why Active Queue Management should worry telco investors
October 28, 2014 By
You may be interested to know that the IETF is pushing a technology that potentially undermines the economic basis for the Internet. This is called “Active Queue Management”. It is the response to a technical problem whose (mis)diagnosis has been labelled ‘bufferbloat’. When long queues build up in routers, real-time and interactive applications are prone […]
How do junk and infidelity make SDN risky?
October 19, 2014 By
I gave a short speech today at SDN & Openflow World Congress in Düsseldorf. For your benefit, I have turned my notes into an article that introduces the ideas of ‘junk’ and ‘infidelity’. These are important engineering terms that aren’t (yet) widely known.
Network Neutrality: Fantasy or Folly?
October 17, 2014 By
I have been invited to write on network neutrality for the industry newsletter VA Telekommarknaden. They are covering the European Telecommunications Network Operators meeting #46GA in Stockholm tomorrow (Friday 17th October).
There is no quality in averages: IPX case study

Here is a crate of apples. Nice, aren’t they? Don’t they all look smooth and shiny! What if I told you that the average apple in this crate was only picked a week ago? So fresh, too!
How is network neutrality like pigeons playing chess?
June 7, 2014 By
The idea of “network neutrality” has been in the news a lot recently. Rather than address it directly, I want to offer you some thinking tools to help position the whole debate in the right place in your head. I have read Nassim Taleb’s brilliant Antifragile, together with other writing of his. He uses three […]
Where are the “structural engineers” for broadband?
June 4, 2014 By 5 Comments
Imagine you are walking out of the elevator on the 57th floor of a skyscraper. You turn to the right, and in front of you is the glass wall of the building. Beyond that is a magnificent view of the city, and many other tall buildings around. How do you feel? Inspired? Awed? Or absolutely […]
Why we need antifragile applications and polyservice networks
April 16, 2014 By Leave a Comment
The radical idea of ‘antifragility’, proposed by the polymath scholar Nassim Taleb, has significant implications for telecommunications. Last December I tweeted a profound thought, originally expressed by my colleague Peter Thompson, who is CTO of Predictable Network Solutions Ltd. It joins the idea of antifragility back to packet networking: “A polyservice network enables the ‘optionality’ that every antifragile […]
