The unnatural nature of networks

Imagine for a moment you’re standing in a remote jungle in the tropics. Around you there are thousands of swaying trees, flapping birds and mildly worrying creepy crawlies. You venture forth, carefully noting the shapes and colours of each species you encounter.

The real reason why network ‘neutrality’ is impossible

In “Net Neutrality: Discrimination, Competition, and Innovation in the UK and US”, Alissa Cooper and Ian Brown explore the relationship between two broadband regulatory regimes and their practical outcomes. The paper is of (paradoxical) interest as it (unintentionally) demonstrates how policy is being made without sufficient understanding of packet network performance.

The appeal against broadband reclassification

A British perspective on a very American process As a new member of the the “Tech Elders”, I was invited to join yesterday’s hearing [PDF] in Washington, DC on the reclassification of broadband Internet access services. The US Federal Communications Commission (FCC) has decreed that Internet access should switch from from being lightly regulated as an ‘information service’ […]

What is a ‘polyservice’ network?

The issue of quality in networks has been long being troublesome, as the underlying science of ‘QoS’ has fallen short of what we need. We have now filled in a significant part of the missing mathematical foundations. The culmination of that work is the ∆Q framework.

Superfit Broadband

The ISP industry has been selling the public (and government) on the benefits of ‘superfast’ broadband. This was a good approach, as historically more quantity did mean better quality. That relationship is now breaking down. A lot of capital is being squandered on delivering substandard experiences.

Quality Arbitrage – Who will be the ‘Uber of telecoms’?

What is ‘quality arbitrage’? When networks went from circuits to packets, they gained a huge increase in efficiency. This was done by sharing the transmission resource more intensively through ‘statistical multiplexing’. At present, all telcos are holding the risks of statistical multiplexing without extracting the corresponding quality of experience (QoE) value. This is because the very […]

Did we build the ‘right’ Internet?

An interview with Prof Andrew Russell The longer I have been in the tech industry, the more I have come to appreciate the hidden complexity and subtlety of its past. A book that caught my attention is Open Standards and the Digital Age by Prof Andrew Russell of Stevens Institute of Technology in New Jersey. This important work shines […]

Contextual comms in agriculture

An Interview with Bruce Rasa, AgVoice The frontier of IT isn’t necessarily found in Silicon Valley, at least not now its fruit orchards are long gone. Since necessity is the mother of invention, those who continue to harvest from capricious Mother Nature have found an ongoing need for innovation.

How ∆Q metrics helped BT to save £millions

∆Q is not only a breakthrough in terms of the science of network performance. It also is transformational to capital and operational costs. Here is one case study from BT Operate (from 2012) to illustrate. If you want to make similar large savings, learn how by coming to my ∆Q workshop in San Francisco next week.
