PING

In this episode of PING, Ege Cem Kirci from ETH Zurich discusses his IMC paper on users perceptions of internet outages, measured using Google Trends. This was presented at the IMC conference held in NIce, France in October 2022.

Ege and his co-authors have been exploring the relationship of Internet outages, (for example caused by weather events) and the information in google trends, with a mechanism to combine snapshots of data by time period which auto-scale, to a single unified time series. In their IMC talk they presented SIFT, a detection and analysis tool for capturing user-affecting Internet outages. SIFT leverages users' aggregated web search activity to detect outages.

In this episode of PING, APNIC's Chief Scientist Geoff Huston explores how APNIC Labs has been able to look inside behaviour in the DNS, to see signs of the "centrality" problem: How much concentration of delivery of service is there, across different market segments of users, and between the supply side (name serving as an authority) and and request side (recursive resolvers)

In this episode of PING, Juan Garcia Pardo from ETH Zurich discusses the Cooperative Lightweight Inter-domain Bandwidth-Reservation Infrastructure (COLIBRI) project for the SCION network, last discussed in episode 18 of PING.

Juan explores the motivations for setting up a bandwidth reservation framework, and how it might be used in practice.

APNIC's Chief Scientist, Geoff Huston, joins PING for his monthly chat, to share his thoughts on the associated trust with routing security and whether it can hold up as a sustainable model.

We'll talk about the history of trust in communication and associated challenges within routing security and the rise and future of Resource Public Key Infrastructure (RPKI) and BGP security.

At the recent APNIC 54 meeting, we sat down with local keynote speaker Alexander Ling, Director of Singapore's Quantum Engineering Programme, in his offices at the National University of Singapore’s Centre for Quantum Technologies.

In this episode, Alex will give us a brief 101 on quantum networking — given it may be a relatively new concept for many of you, even though it's been in development for quite some time — and discuss its current and pending use cases in the next 3 to 5 years, including via satellite technology.

Watch Alex's APNIC 54 keynote presentation From HTTP to HTTQ - Working Towards the Quantum Internet.

APNIC's Chief Scientist, Geoff Huston, joins PING for his monthly chat, to warn the service provider industry about pressuring regulators to make content providers pay to use their networks; a situation currently playing out in Korea as we chatted about in Episode 13.

Korea v. Content Provider: When the customer isn’t always right

As he outlines in his recent post, Geoff forecasts the consequences of turning our backs on net neutrality which could jeopardize service providers' current hold on the provision market and Internet users’ access to sites like Netflix and YouTube, increase the centrality of the Internet and in some cases compromise the security of certain economies communication infrastructure.

In this episode, we’re returning to a topic that we last discussed in Episode 20, with Robin Marx, and unpacking the intricacies and perceived complexities of the QUIC and other similar new protocols.

To help, we’ve invited Larry Peterson and Bruce Davie, who among their extensive list of experience spanning the past thirty years, are co-authors of the renowned ‘Computer Networks: A Systems Approach’ textbook, which is now in its fifth edition and open source.

APNIC's Chief Scientist, Geoff Huston, joins PING for his month chat, to share his thoughts on discussions at the recent meeting of the Decentralized Internet Infrastructure Research Group (DINRG) at IETF 114.

The DINRG investigates open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery with a focus on infrastructure services that can benefit from decentralization or that are difficult to realize in local, potentially connectivity-constrained networks.

For Geoff the discussion about whether technology has led to centralization is misplaced — technology was merely and will remain simply a lever that 'The Big' use to remain big. Rather the discussion needs to focus on the economic factors that have historically repeated themselves and allowed the biggest companies of the world to control their markets.
