Future of Broadband workshop presentation - ITU Telecom World 2013Martin Geddes
Is "bandwidth" the right resource model for broadband? This presentation suggests that the telecoms industry is in a death spiral because it has fundamentally misunderstood the nature of the resource it offers. In its place it offers a "quality" model that has the properties we desire, and enables us to properly match supply to demand.

Digital supply chain quality managementMartin Geddes
We've figured out how to send physical goods around the world: aggregate them into containers. We're still struggling how to do digital good, which we disaggregate into packets. Here's the answer.
The goal of this presentation is to share exemplars of important broadband Internet access performance phenomena. In particular, we highlight the critical role of stationarity.
When they have non-stationarity, networks are useless for most applications. We show real-world examples of both stationarity and non-stationarity, and discuss the implications for broadband stakeholders.
These phenomena are only visible when using state-of-the-art high-fidelity metrics and measures that capture instantaneous flow.
Superfast or superfit? The case for UK broadband policy reformMartin Geddes
This is a critical moment for UK digital infrastructure policy. The context is one of rapid political, market and technological change. As a nation, we face important decisions over topics like post-Brexit regulation, universal service delivery, Openreach independence, TETRA replacement and 5G readiness. The imperative is to reflect on whether our historic approaches will meet our future needs. Where we anticipate a shortfall, we must act to protect our long-term national interest.
This paper aims to educate policymakers about one specific shortfall: the growing ‘capability gap’ between broadband demand and supply.
It makes two recommendations.
This unwanted situation is avoidable by two readily attainable changes in our policy approach.
Firstly, our policy metrics need to reflect the readiness of broadband infrastructure to support both present and future demand.
Secondly, the money needs to move to incentivise the right market behaviours to create a correspondingly fit-for-purpose supply.
When these reforms are enacted together, this will help to position the UK with a world-class infrastructure ready to attract capital and talent on a global scale.
Broadband service quality - rationing or markets?Martin Geddes
"Net neutrality" is implicitly framed as a debate over how to deliver an equitable ration of quality to each broadband user and application. This is the wrong debate to have, since it is both technically impossible and economically unfair. We should instead be discussing how to create a transparent market for quality that is both achievable and fair.
Introduction to network quality arbitrageMartin Geddes
Many large operators have expressed a desire to undertake disruptive change, and we have often proposed an agenda for such change. What typically happens is that, after several rounds of engagement, we observe that there is little mainstream organisational appetite to engage in disruption. Why so?
The main reason is a perception gap between the current state of the art (which any leading operator delivers) and our understanding of the state of the possible (which most operators are very far from). This gap exaggerates the risks of engaging in disruption, and underestimates the potential rewards.
Another reason is that our industry as a whole implicitly believes that network service quality is a matter of detecting and rectifying ‘faults’. This framing inhibits the consideration of the alternative paradigm of networks as resource trading spaces. As a result, the significant ‘quality arbitrage’ that exists in all IP networks is not visible.
Operators face the risk that others will exploit the arbitrage opportunity, to their serious commercial disadvantage. This has happened before, e.g. with TDM and the rise of ISPs, and is happening now with SD-WAN. We propose that a larger multinational operators need to proactively initiate the disruption via a new business unit.
The End of Information Technology: Introducing Hypersense & Human TechnologyMartin Geddes
If we were to climb into a time machine and set the dial for ten years into the future, what might personal communications look like? Might you inhabit a soothing virtual reality where your conference call takes place in a simulated lakeside villa? Might you consult with a virtual doctor? Employ a “Guardian Avatar” to act autonomously on your behalf eliminating online drudgery and security concerns? Although no particular future is certain, the seeds of what is to come can always be found within the present reality, albeit often only in retrospect.
Sample proposal summary for quality arbitrage business unitMartin Geddes
The telecoms industry is getting to grips with quality and performance. The current system has a weak control over quality, and many pricing mismatches. As a result, there are arbitrage opportunities everywhere. This presentation for a global telco proposed a new business unit to take advantage of them.
The future of computing is a symbiosis of machines and people. To achieve this we need an "operating system" upgrade for digital technology. We all need a Guardian Avatar to help us to navigate the "metaverse", and to care for us and protect us.

FCC Open Internet Transparency - a review by Martin GeddesMartin Geddes
How technically sound and effective are the Federal Communications Commission's proposed rules on broadband measurement? This short informal report evaluates them and finds a concerning shortfall.
The human race is on a journey from beasts to superheroes to gods. This short presentation frames our progression, and the key challenge that we need to face to get there.
Beyond 'neutrality' - how to reconnect regulation to reality?Martin Geddes
How can we anchor broadband policy in technical reality? The key is to understand that there is a critical missing element missing from the current literature: the stochastic nature of broadband. This has significant and serious implications for all regulators, ISPs and consumer advocates.
The issue of quality in networks has been long being troublesome, resulting in endless deferral. It was a hard issue for the pioneers to deal with ‘quality’ and ‘QoS’ as the underlying mathematics was insufficient to support their ambitions. We have now filled in a significant part of the missing mathematical foundations. The culmination of that work is the ∆Q framework.
As a by-product of this framework, a new approach to sharing quality has become possible: a polyservice network. We believe that this is a significant conceptual and practical advance. However, we have (until now) lacked industry standard terminology to describe it.
This short presentation introduces the idea of a polyservice network, and contrasts it with pre-existing approaches to ‘priority QoS’.
The ISP industry has been selling the public and government on the benefits of 'superfast' broadband. This presentation argues that the goal should instead be 'superfit' broadband.
The perception gap: the barrier to disruptive innovation in telecomsMartin Geddes
The 'state of the possible' in telecoms is a long way ahead the 'state of the art'. The new science of network performance enables a large leap in customer experience and cost. However, the perception among operators is that only relatively small, incremental improvements are possible.
This presentation explores the reasons for this 'perception gap' between what is seen to be possible, and what actually is. It draws on our work at senior levels for tier 1 operators, as well as examples from outside the telecoms industry.
Overcoming this gap opens the possibility to disruptive innovation. Who will seize the opportunity? Incumbents, challengers or new entrants?

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Economy Standard Premium
Airlines offer multiple tiers of service, based on comfort, rather than arrival
time (bar a bit of queue-jumping at check-in). In networks, the tiers of
service are based on how much you can time-shift traffic.
