Today's Internet faces severe challenges including:
* IPv4 address exhaustion
* explosion of BGP tables and IP routing tables
* exponential traffic growth (which might not be a problem after all)
This is an introduction about 6RD, a protocol to transport IPv6 in IPv4 invented by Remi Despres. It is the protocol for SPs who want to provide access to their customers over an IPv4 Internal Backbone.
It is actually 6to4 protocol customized for Service Providers with a configurable prefix.
It has been deployed in 2007 by Free, a French SP and has proven its scalability and its reliability.
It is supported by CISCO in IOS and in other devices like ASR1K for the BR and in more and more cheap CPE for access as well as Linux.

The Impact of IPv6 to Net Politics
CGN Killer IPv6
- Why CGN isn't a good concept for the future, but IPv6 is.
464XLAT Tutorial, by Masataka Mawatari.
Presented at the APNIC 40 "Hypes? Fanfares? Fads? Wading through the muddy IPv6 puddle" session, Wed 9 Sep 2015.
IPv6 is the most recent version of the Internet Protocol (IP), and was developed by IETF to overcome the inevitable exhaustion of IPv4 addresses. In order to simplify the transition towards IPv6, the protocol iterated very little on how IPv4 operates other than offering more address space. This inadvertently produced the exact opposite of the intended effect: with no compelling new features for anyone outside of network engineering, IPv6 deployment has been hampered for decades, as developers find increasingly creative ways of efficiently using IPv4 address space rather than bearing the cost of transition.
In this talk, Fastly Network Engineer João Taveira discusses these protocol design failures and instead explain how Fastly re-architected its infrastructure around IPv6. By addressing IPv6 in a clean-slate manner, Fastly avoided perpetuating many of the mistakes of IPv4, and the resulting network architecture has the potential to significantly affect the performance, resilience, and economics of content delivery.

You may have hoped to retire before IPv6 became a reality, but unfortunately the IPv4 address exhaustion came too fast. For the rest of us, we’re going to bite off a small piece of the 15-year old IPv6 pie and talk about how to get started!
• Address format refresher
• IPv4 and IPv6 protocol comparison
• IPv6 neighbor discovery and auto-configuration
• Current migration and coexistence strategies
• ICMPv6, DHCPv6, and DNSv6
• How to get started at home

IPv6 Success Stories– Network Operators Tell All!
Asela Galappattige (Sri Lanka Telecom); Senevi Herath (LEARN); Patrick Okui (Network Startup Resource Center); Matsuzaki Yoshinobu (IIJ)
In this session, we invite network operators to share their IPv6 success stories and lessons learned along the way that can help other managers of networks deploy IPv6. How did they do it? What technical, organizational, and political challenges did they face? Attendees will gain vital insight as network operators lay out the stages for IPv6 implementation—creating the business case for management buy-in, initiating a planning process, flipping the switch, and, finally, gathering measurements and proving success.
The Internet industry is undergoing a fundamental change as it transitions from IPv4 to IPv6. These slides are from the May 2011 webcast which provided an introduction to IPv6, covering the various issues and concerns about this new protocol, as well as the opportunities it offers.
The webcast featured Limor Schafman and Dale Geesey, IPv6 experts, discussing what IPv6 is, why it’s different, its advantages, the transition period from IPv4 and how organizations should start preparing.

BGP: Whats so special about the number 512?GeoffHuston
It was reported that parts of the Internet crashed when the number of routes in the Internet's Inter-domain routing table (BGP) exceeded 512K routes. This presentation looks at the growth of the Internet's routing table and how this correlates to the capacity and speed of memory in hardware routers.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
"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.
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.
