In this episode, we chat with Anant Shah, Principal Architect at Edgecast, about the challenges with measuring video streaming quality of experience. We'll discuss the fundamentals of video streaming, including the protocols, how it is delivered and different vantage points from which it can be measured.

Understanding the challenges associated with delivering and measuring content can provide insight into how we need to improve observability in the Internet as a whole as well as how we can develop the network to deliver low latency content in the future.

APNIC's Chief Scientist, Geoff Huston joins us again on the show, this time to discuss three related presentations by Google, ISC and Mozilla that caught his attention during the recent IETF 114 and DNS-OARC 38 meetings on securing the DNS against spoofing.

DNS spoofing involves third parties intercepting and responding to queries for benign or malicious purposes; recent studies show that DNS spoofing has more doubled since 2016.

Google is protecting its DNS service against spoofing using multiple methods including using a combination of DNS cookies, randomizing the choice of name servers, stripping duplicate queries from the outbound queues, performing rate limiting and unilaterally probing for support of Authoritative DNS over TLS (ADoT); it projects that these measures will cover 99% of queries after the various rollouts are complete.

While such results are impressive, Geoff and others argue that the widespread use of DNSSEC could do just as good as a job and with little impact on performance, as per ISC's and Mozilla's findings in their recent studies.

We’re continuing the theme of our last episode and learning more about the intricacies and perceived complexities of the QUIC protocol from one of its contributors and proponents Robin Marx, a web protocol postdoc researcher at KULeuven in Belgium and soon-to-be technical solutions architect at Akamai.

Having researched HTTP2 performance as part of his PhD, Robin became involved in the development of HTTP3 and QUIC in the IETF while they were being designed. He also created the popular QUIC and HTTP/3 debugging and testing tools qvis and qlog.

In this episode, we discuss how the perceived complexities are unwarranted and how similar perceptions directed at other new protocols can impact innovation, especially from new contributors to forums like the IETF. Robin also shares his experience with contributing to the development of QUIC in the IETF, and the importance of user experience when it comes to measurement.

In this episode, APNIC’s Chief Scientist, Geoff Huston joins us to discuss a new measurement project that he and his APNIC Labs colleague Joao Damas have established to measure the use and performance of the QUIC protocol (RFC 9000).

Although QUIC has only recently been standardized by the IETF (May 2021), it has been around since 2012 with an initial public release included in Chromium version 29, in August 2013. After nine years, how widely is it being used and is it living up to its billing and improving the reliability, security and speed of the Internet?

Today’s Internet is a Frankenstein’s monster of parts that have been bolted together. If it was a house, it would be a knock-down job — far easier to start from scratch.

This is easier said than done or so many thought as we’ll come to learn in this episode featuring Nicola Rustignoli a founding engineer at the SCION Association, which is taking a clean-slate approach to overcoming the architectural limitations of today’s Internet, to provide route control, failure isolation, and explicit trust information for end-to-end communication.

In this episode, APNIC’s Chief Scientist, Geoff Huston, joins us to discuss IPv6 — a topic he has investigated exhaustively over the last 30 years.

Specifically, we’re talking about the seemingly never-ending transition to IPv6, the hallmarks it shares with previous IP transitions, how Network Address Translation (NAT) has hindered its deployment for the good and bad of the Internet, and whether 100% IPv6 is even the end goal given how far technology has come since IP was first implemented.
