Happy Eyeballs Version 3: Better Connectivity Using Concurrency

Many communication protocols operating over the modern Internet use hostnames.  These often resolve to multiple IP addresses, each of which may have different performance and connectivity characteristics.  Since specific addresses or address families (IPv4 or IPv6) may be blocked, broken, or sub-optimal on a network, clients that attempt multiple connections in parallel have a chance of establishing a connection more quickly.  This presentation describes the requirements for algorithms that reduce this user-visible delay and provides an example algorithm, referred to as “Happy Eyeballs” over its various iterations.

IPv6 + CDN

Date: November 30, 2023
Time: 16:00 UTC - 17:00 UTC
Register: Register
This session will discuss the role of a Content Delivery Network (CDN) and its role in modern network infrastructure as it impacts IPv6 and IPv6 Extension Headers. 
CDNs play a crucial role in optimizing web content delivery by reducing latency and improving performance. Here’s a breakdown of the key components
1. Edge Servers (or Cache Servers):
   – These are servers distributed across various geographical locations, strategically placed closer to end-users.
   – Edge servers store cached copies of web content, such as images, videos, stylesheets, scripts, and other resources, from the origin server.
   – When a user requests content from a website, the CDN’s edge server closest to the user responds to the request if it has the requested content in its cache.
   – Edge servers help reduce latency and improve load times because they are physically closer to users, minimizing the distance data needs to travel.
2. Origin Server:
   – The origin server is the original web server where the website’s content is hosted and managed by the website owner (in your example, Facebook’s servers).
   – While edge servers cache and serve content, the origin server is the authoritative source for the website’s content.
   – CDNs periodically fetch or update content from the origin server to keep their caches up to date.
3. IPv6 Extension Headers:
   – IPv6 Extension Headers are additional headers used in IPv6 packets to provide extra information or services. These headers are added to the standard IPv6 header to support various features or optimizations.
In this session, we will discuss the process as well as potential problems with IPv6 implementations as well as IPv6 Extension Headers.

Enhancements for Neighbour Discovery

Neighbour Discovery for IPv6 forms the cornerstone of efficient network communication in the IPv6 realm. It facilitates address resolution, duplicate address detection, and router discovery, making it indispensable for seamless communication across IPv6 networks. However, as enterprises migrate to IPv6, the conventional ND6  protocol may face challenges in terms of scalability and performance.

To address these limitations, our research focuses on incorporating the enhancements proposed for 6lowpan in RFC 6775 and 8505 into the mainstream ND6 protocol. These RFCs present innovative solutions that improve the speed and accuracy of neighbour discovery while optimizing the use of multicast messages.

In particular, RFC 6775 outlines mechanisms for optimizing ND6 for low-power and lossy networks (6Lowpan). By bringing these optimizations into the mainstream ND6, we aim to enhance its performance and adaptability, especially in enterprise settings.

Additionally, RFC 8505 proposes solutions to reduce unnecessary traffic and processing overhead in ND6, further optimizing its performance in larger networks. This reduction in overhead is critical for scaling ND6 to meet the demands of modern enterprise environments.

In this presentation, NITK students Sudesh, Advaith, and Kavya will elaborate on our hypothesis, the advanced packet modifications, and their efforts in implementing these upgrades in FreeRtr – an open-source IPv6 routing software. They have been actively involved in the implementation of these enhancement.

In the process of planning for an IPv6 deployment, some desire to create a design analogous to private RFC1918 deployments. In this webinar we will discuss the structural differences between technologies such as RFC1918 and unique local addressing (ULA). We will address topics such as why they aren’t the same, where they make sense, where they don’t. We will also discuss the underlying implementations of address selection and how it relates to IPv6 differently than IPv4. Webinar participants should expect a mix of architectural policy and technical depth and come away with a better understanding of ULA and the mechanisms that define it.

6LoWPAN Trace Reading

Time: 15:00 UTC - 16:00 UTC
Slides: Slides
Recording: Recording
Register: Register

The 6LoWPAN adaptation layer defines compression, fragmentation and reassembly, and frame delivery mechanisms for IPv6 datagrams. As specified in RFC 4944, when an entire IPv6 datagram fits within a single IEEE Std 802.15.4 frame, then the datagram is transmitted unfragmented without adding a fragmentation header in the LoWPAN encapsulation. On the opposite hand, if the compressed IPv6 datagram is larger than the IEEE Std 802.15.4 MTU (i.e., 127 bytes), then fragmentation is required to split the large datagram into multiple link-layer fragments of up to 127 bytes. The length of each link fragment is specified in multiples of eight bytes. The first part of this talk will be dedicated to the whole process of 6LoWPAN Fragmentation and Reassembly operation. The second part of the talk will be dedicated to 6LoWPAN Frame Delivery modes, the mesh under and the route over (or Per-Hop Fragmentation and Reassembly mode). Both approaches are widely employed in the Smart Grid networks around the world. The first mode takes place at the 6LoWPAN adaptation layer, where the nodes require the knowledge of the routes at Layer 2 based on MAC, whereas the second mode does it at Layer 3 based on IP. Finally, in the third and last part of the talk, an alternate approach called 6LoWPAN Fragment Forwarding (6LFF), i.e., RFC 8930, will be presented, whereby an intermediate node forwards a fragment without reassembling the complete IPv6 datagram first.

Concerned about adding a new protocol to your IP stack? Is someone in your company demanding that you have that capability on your mainframe? Don’t know what needs to be done and how much effort is involved? And what does it all mean?
Rob has done the hard work for you and can tell you what it takes to enable your mainframe systems for IPv6. This presentation will give you the few steps you need to get you going, to get IPv6 active on your z/OS system.
Rob started programming mainframe computers in 1971, and learned an exceptional array of languages, tools and techniques, all without internet assistance. He did some dazzling database work in the `80s, and wrote over half of the first online registration system for the University of Toledo. In the ‘90s he did contracts with three oil companies, a software company and a credit bureau, involving VM, MVS, VSE, OS/2, several flavors of Unix, and an equal variety of networking protocols. He is now with Chemical Abstracts Service, a division of the American Chemical Society, supporting z/OS, z/VM and Linux, along with proprietary networking software. He has been involved with and a fan of IPv6 since early this century, performing the configuration and software upgrades required to support it on the mainframe. He happily notes that the mainframe was the first platform configured for it, with applications using IPv6 sockets exclusively. Rob is also co-author of RFC8250.

Introduction to IPv6 Security

Date: October 8, 2020
Time: 00:00 UTC - 00:00 UTC
Slides: Slides
Recording: Recording

How security will be handled in IPv6 is a question asked by many. Myths abound. In this session, we will start to look at:

• NAT is not a firewall (security by obscurity)
• Complexities introduced by multiple stacks
• Risks introduced by not considering IPv6
• Reconn attacks and defense
• Local network attacks and defense
• Unauthenticated NDP (similar to ARP)
• Cache table exhaustion and ping-pong attacks
• Rogue device attachments
• Mitigations
• Extension Headers
• ICMPv6

This is only a start. In the following year, we plan to do a more detailed investigation of this critical area. There will be follow-on webcasts. In the survey to enterprises, many people said that this was a topic they considered very important.

This webinar will be taught by Jon Worley (ARIN) and Nalini Elkins (INTC). This is a part of the Community Grant to INTC from ARIN.
Jon will start by helping you better understand IPv6 address planning, how to determine the right block size for your organization, and how to plan for growth. We will include some real-life examples and even an opportunity to try your hand at planning for your own organization! Nalini will go into even more detail and provide some rules for IPv6 address planning.In this session, we will:

  • Review the important prefixes needed for an IPv6 address plan,
  • Do a sample address plan together,
  • Discuss how a good address plan makes security and routing policy easier,
  • Consider numbering your LAN segment, SSID, or VLAN,
  • Consider numbering for sites, backbone, links, Consider how to remember your addresses for diagnostics and troubleshooting, and
  • Look at plans that other enterprises have done.

Jon Worley is the Senior Technology Architect with ARIN and has been a member of the Registration Services team since 2004. He has experience with all ARIN policies and procedures for requesting, managing, and transferring IP addresses and AS numbers, including technical services such as ARIN’s RESTful API. Jon has spoken about these topics as well as IPv4 depletion and IPv6 adoption at many ARIN events.

IPv6 Transition  Mechanisms and DHCVPv6

This session is funded with a grant from ARIN. It is a two-hour webinar. 

Dual Stack and Transition Mechanisms

 Enterprises rarely switch over from IPv4 to IPv6 in one step. Generally, companies will run dual-stack for a time, where both IPv4 and IPv6 are available on devices. This doesn’t solve most of the problems IPv6 was designed to solve, so we will discuss the benefits and drawbacks of:

  • Dual-stack
  • NAT44
  • Dual-stack Lite
  • NAT64/DNS64
  • 464xlat
  • MAP-T
  • MAP-E
  • IPv6-Only

DHCPv6Although IPv6 provides new addressing possibilities (SLAAC), most enterprises will want to continue using DHCP — which is now DHCPv6. We will describe how a client finds a DHCPv6 server, what information it can request and expect back. We will compare DHCPv6 to SLAAC.  We will discuss:

  • DHCPv6 Solicit Advertise, Request, Reply
  • DHCPv6 multicast addresses
  • IA_NA, IA_PD
  • Prefix “hints” to request the same prefix, or any prefix of a certain size
  • Additional information (DNS, transition mechanism, etc.)
