The unconscious and near-universal belief is that packet networks are a telecoms service, and one that constructs an ‘additive’ resource called ‘bandwidth’. This is demonstrably technically false. They deliver distributed computing services, as they calculate how to divide up an underlying telecoms transmission resource.

Whilst people argue over the virtues of net neutrality as a regulatory policy, computer science tells us regulatory implementation is a fool’s errand.

Network performance science took a small step forward today, with the first “commodity” high-fidelity service quality measurement data.

There is a new telecoms and cloud industry growth sector, Virtual Quality Networks (VQNs). My belief is that VQNs are due to become as pervasive for enterprise users as Virtual Private Networks (VPNs). They will be far more profitable as they are much more valuable. Here are a dozen reasons why VQNs are strong candidate […]

Pretty much every aspect of the present Internet’s design needs rethinking. It does one thing really well – abstracting away the implementation of connectivity. Everything else is pretty borked from inception.

This is the story of Sprint’s pioneering, and failed, effort to become the first telco to turn itself into an open application and business platform. The story starts in 1999 in Dublin, Ireland during a warm and pleasant summer.

We have been trying to build packet networks without having a basic and essential mathematical concept. This matters. A lot.

Every IP network will at times offer too much quality for too little money, creating an arbitrage opportunity. This presentation gives an introduction to the concept and how network operators can respond.

The IETF has the final day of its 98th meeting in Chicago today (Friday 31 Mar), far away from here in Vilnius. The Internet is maturing and becoming indispensable to modern life, and is transitioning to industrial types of use. Are the IETF’s methods fit-for-purpose for the future, and if not, what to do about […]

I have summarised my last seven years of work in one slide.
