- The APRICOT-APAN 2015 conference network offers dual-stack and 464XLAT connectivity for IPv6 access. - 464XLAT allows IPv4-only devices to access the IPv6 network through address translation at the Customer Location Address Translator (CLAT) and Port-Limited Address Translator (PLAT). - Statistics on the 464XLAT network at the conference venue show uplink and downlink traffic volumes and the number of WiFi associations using the 464XLAT SSID.

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.

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

Getting started with IPv6

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. For a full overview of all the principle Transition Protocols, please refer to this blog: http://www.fastlaneus.com/blog/?p=335 And this video: http://youtu.be/TqmKCqYsk5A And a Video of this presentation is currently uploading on youtubes: http://youtu.be/PrnFWgqlhj0 Fred Bovy IPv6 Forum Gold Certified Engineer IPv6 Forum Gold Certified Trainer CISCO 15 years CCIE #3013 CISCO 18 years CCSI #33517 (before was #95003)Meet me on Twitter: FredBovySkype: FredericBovyBlog: http://www.fastlaneus.com/blogEmail: fred.bovy@fastlaneus.com, fred@fredbovy.com

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.

From KubeCon to ContainerDays, eBPF is trendy in the Cloud Native world. What is eBPF, and why is it revolutionary, and what can it bring to you specifically? Through concrete examples applied to observability, networking, and security, this talk will explain the principles of eBPF and its concrete advantages to connect and secure Cloud Native applications. This talk will explain what is eBPF, why it is revolutionary is several fields, give examples of tools using eBPF and what they gain from it, and open up to the future of that technology.
