The document discusses Apache Traffic Server's plans to implement QUIC, including:
- Their goal is to start development of a QUIC implementation, with a first draft coming soon.
- QUIC is a new protocol that implements improved TCP and TLS over UDP. It includes congestion control and loss detection.
- There are 4 QUIC specifications covering the core transport, loss detection, TLS mapping, and HTTP mapping.
- They discussed initial prototype issues and a revised design, with milestones including experimental ATS support in 2018.
Matt Summers, NCC Group - Web technology has changed a lot in the last 25 years but the underlying transport mechanism has stayed the same. The web we have today was not designed for the plethora of new device types and communication methods but things are changing and you probably don’t even know it. You probably don’t even notice the problem because it is so ingrained. In this presentation we are going to delve into the problems with the web and how we use it today. We will also take an in depth look at the proposed solutions for the next generation web and the implications that come with it.

HTTP/2 and QUICK protocols. Optimizing the Web stack for HTTP/2 erapeychevi
The new HTTP/2 protocol which is going to replace HTTP 1.1 was finished on February. Together with it, QUIC is being developed rapidly. Discover why are they so important for the Web and how will they influence the way we optimize the Web stack for the HTTP/2 era.

HTTP/3 over QUIC. All is new but still the same!Daniel Stenberg
HTTP/3 is the designated name for the coming next version of the protocol that is currently under development within the QUIC working group in the IETF. HTTP/3 is designed to improve in areas where HTTP/2 still has some shortcomings, primarily by changing the transport layer. HTTP/3 is the first major protocol to step away from TCP and instead it uses QUIC.
Daniel Stenberg does a presentation about HTTP/3 and QUIC. Why the new protocols are deemed necessary, how they work, how they change how things are sent over the network and what some of the coming deployment challenges will be.
The Open vSwitch kernel datapath may have flows offloaded to hardware using the TC Flower classifier and related actions. This is a powerful mechanism to both increase throughput and reduce CPU utilisation. This presentation will give an overview of the evolution of this offload mechanism: features available in OvS v2.8, those targeted at v2.9 and possible future directions.
The TC Flower Classifier allows control of packets based on flows determined by matching of well-known packet fields and metadata. This is inspired by similar flow classification described by OpenFlow and implemented by Open vSwitch. Offload of the TC Flower classifier and related modules provides a powerful mechanism to both increase throughput and reduce CPU utilisation for users of such flow-based systems. This presentation will give an overview of the evolution of offload of the TC Flower classifier: where it came from, the current status and possible future directions.

As you will see in this film, there are a lot of questions from an interested and educated audience.
Daniel Stenberg is the founder and lead developer of the curl project. He has worked on HTTP implementations for over twenty years. He has been involved in the HTTPbis working group in IETF for ten years and he worked with HTTP in Firefox for years before he left Mozilla. He participates in the QUIC working group and is the author of the widely read documents ”HTTP2 explained” and ”HTTP/3 explained”.
Keynote given at DRCN2018, shows that innovation is back in the transport and network layer with a description of Multipath TCP, QUIC and IPv6 Segment Routing.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

"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.

4. IETF QUIC
• It was mostly HTTP/2 over UDP + α
• It is something else over UDP + α
• Totally new protocol to ATS
≈ Improved TCP + TLS + Improved HTTP/2
HTTP over QUIC
UDP
TLS 1.3
QUIC
TCP-like congestion control, loss detection
5. 4 specifications & 2 layers
1.Core Transport Protocol
2.Loss Detection and Congestion Control
3.TLS Mapping
4.HTTP Mapping
6. 4 specifications & 2 layers
1.Core Transport Protocol
HTTP over QUIC (4)
UDP
TLS 1.3
QUIC (1,2,3)
TCP-like congestion control, loss detection
• Implements improved TCP with
modern technologies on UDP, in
userland
• Existing hardware should be
able to transfer QUIC traffic
without any change
• Protocol version is negotiable
7. 4 specifications & 2 layers
2.Loss Detection and Congestion Control
HTTP over QUIC (4)
UDP
TLS 1.3
QUIC (1,2,3)
TCP-like congestion control, loss detection
• Ensure reliable transfer
• Difference from TCP is “HOW”
• Modern algorithms
8. 4 specifications & 2 layers
3.TLS Mapping
HTTP over QUIC (4)
UDP
TLS 1.3
QUIC (1,2,3)
TCP-like congestion control, loss detection
• Current draft uses TLS 1.3
• Key exchange will be done at
the beginning of session on a
dedicated QUIC stream
• Need to implement it with low
level APIs in crypto libraries
9. 4 specifications & 2 layers
4.HTTP Mapping
HTTP over QUIC (4)
UDP
TLS 1.3
QUIC (1,2,3)
TCP-like congestion control, loss detection
• Some parts are the same as
HTTP/2
• Many parts of HTTP/2 will be
moved down to QUIC transport
layer
• Frame structure will be changed
• HPACK will be replaced
11. Issues
• TCP (stream) vs UDP (datagram)
• Code for UDP is not maintained
• Multiplexing is on transport layer
• HTTP over QUIC looks like HTTP/3 (totally different)
12. Current design (2nd try)
Too many things to talk here…
• No QUICNetAccept
• No changes for VIO itself
• ProxyClientSession isn’t
used for now
• Most parts will be into
iocore/quic/
13. Milestones
• 2017 May — Prepare for development
• 2017 Jul — Implement first implementation draft
• ATS Summit 2017 Fall — Report result of interop
• 2018 May — Add experimental support (ATS 8.0)
