IPv6 Webinars Phase II

ULA in IPv6 Enterprise Networks

Oct 27, 2022

8:30 PM IST

Nick Buraglio

[Video] [Slides

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.

This session will be presented by Nick Buraglio who has been in the networking industry since 1997, focusing primarily on service provider technologies, high performance networking, and disruptive technologies. He is currently in the planning and architecture team for Energy Sciences Network (ESnet) working on next generation traffic engineering and as the Department of Energy IPv6-only implementation lead.

6LoWPAN Trace Reading

Oct 06, 2022

8:30 PM IST

Georgios Z. Papadopoulos

[Video] [Slides

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.

This session will be presented by Georgios Z. Papadopoulos who has received the prestigious French national ANR JCJC 2017 grant for young researchers. He has been involved in the organization and program committee of many international events, such as IEEE ISCC’20, IEEE DIPI’19, AdHoc-Now’18, IEEE CSCN’18, GIIS’18, IEEE ISCC’17. Moreover, he has been serving as Associate Editor for Wireless Networks journal and Internet Technology Letters since 2018. He is author of more than 60 peer-reviewed publications in the area of computer communications, networks and cybersecurity. He actively participates at the IETF standards organization with multiple drafts in the ROLL and RAW Working Groups. His research interests include Industrial IoT, 6TiSCH, 6lo, LoRa & LPWAN, Wireless Battery Management System, Smart Grid, Cybersecurity and Moving Target Defense. Dr. Papadopoulos has received the Best Ph.D. Thesis Award granted by the University of Strasbourg and he was a recipient of two Best Paper Awards (IFIP Med-Hoc-Net’14 and IEEE SENSORS’14).

Mesh routing is difficult, mesh routing for low power and lossy networks is straight up comatose. This session will help understand how the signalling/messaging works and depict sample packet captures for RPL signalling from real environments. It will also introduce tools apart from wireshark, such as scapy that can help construct/deconstruct the messaging. Obtaining performance data for mesh networks is another aspect covered in the session. What makes taking performance difficult? What are the best practices and some of the case studies? The session will also provide a demo into creating a sample 10 node RPL network on a laptop and getting the packet capture for the network formation.

[Video] [Slides

RPL, the IETF standard for routing in low power lossy networks, was designed to meet unusual constraints in terms of scale (high), device capabilities (limited), and link reliability and capacity (very low). To meet those constraints, RFC 6550 introduced a number of innovations with the use of anisotropic routing, stretched P2P path, autonomic properties, objective functions, multi-topology routing, and a distance-vector operation that is proactive in setup but reactive in maintenance. RPL is now being extended at one extreme with a fully ADHOC mode called AODV RPL, and a centrally controlled mode called Route Projection. This session will browse through the main features of RFC 6550 and the route projection work.

 

The presenter, Pascal Thubert from Cisco, is a co-editor of RFC 8655 (the DetNet architecture), RFC 9030 (the 6TiSCH architecture), and the WIP draft RAW architecture, and well as the RPL routing protocol (RFC 6550), the 6LoWPAN Header Compression (RFC 6282) and Neighbor Discovery (RFC 8505 / 8928 / 8929) protocols.

In this IPv6 and 6LoWPAN Webinar, a detailed overview of the 6LoWPAN Adaptation layer will be given. Indeed, this webinar is dedicated on how 6LoWPAN enables to use of IPv6 over IEEE Std 802.15.4 networks. During this webinar, the following three objectives will be covered:

  • First, the principles of IPv6 Header Format overview will be given, then the constraints that IPv6 presents over IEEE Std 802.15.4 technology are explored, and finally, an overview on 6LoWPAN Adaptation layer is introduced.

  • The second objective is dedicated on 6LoWPAN header compression (i.e., RFC 6282) and IPv6 packet fragmentation mechanisms (i.e., RFC 4944) that allow the transmission of IPv6 packets over IEEE Std 802.15.4 radio links.

  • The third and the last objective of this webinar is dedicated on standardized fragment forwarding approaches. This objective is split in two parts. In the first part, the two Frame Delivery modes (i.e., Mesh-Under and Route-Over) are described, while in the second part, an alternate approach called 6LoWPAN Fragment Forwarding (6LFF) is introduced, whereby an intermediate node forwards a fragment without reassembling the complete IPv6 datagram first (i.e., RFC 8930). Moreover, a 6LoWPAN Selective Fragment Recovery mechanism will be presented (i.e.,RFC 8931).

6TiSCH and Deterministic Networks

[Video] [Slides

Despite the general benefits experienced with converging data, mail, voice, and video over IP, a number of domains in Operational Technology (OT) including Industrial IoT, vehicular automation, professional audio, and so on, still rely on semi-proprietary technologies for their the network operations. This is because machine-to-machine communications require deterministic properties such as guaranteed worst case latency and jitter and high reliability that traditional IP, which is based on statistical multiplexing and reactive congestion management, cannot offer.

In recent years, new work at IEEE 802.1 TSN and at the IETF with 6TiSCH, DetNet, and RAW, propose an evolution to IP networks that enable those deterministic properties for well characterized flows, over initially wired and then wireless networks. This session will introduce the concept of deterministic networking and how it applies to IoT, keeping in mind that machines are not necessarily small and constrained, and that automation applies to large things such as trains and nuclear plants. The architectures behind DetNet, 6TiSCH, and RAW, how they relate and specifically how they can leverage IPv6, will be browsed at a high level.

 

The presenter, Pascal Thubert from Cisco, is a co-editor of RFC 8655 (the DetNet architecture), RFC 9030 (the 6TiSCH architecture), and the WIP draft RAW architecture, and well as the RPL routing protocol (RFC 6550), the 6LoWPAN Header Compression (RFC 6282) and Neighbor Discovery (RFC 8505 / 8928 / 8929) protocols.

Internet of Things:
The Standards Landscape

Microcontrollers have enabled adding processing and communication to many physical objects, but the result is not a simple copy of a general-purpose computing environment. Bringing these objects into the Internet requires attention to their specific constraints. Since 2005, the Internet Engineering Task Force (IETF) has been shaping Internet protocols toward the special requirements of such constrained devices, addressing a full stack from adaptation layers to the application layer, including security protocols. Looking at 17 years of standardization, what have we achieved, and what still needs to be completed to arrive at a true Internet of Things?

Carsten Bormann likes bringing the Internet to odd places. Honorary professor for Internet Technology at the Universität Bremen, he is a member of its Center for Computing and Communications Technology (TZI). His research interests are in protocol design and system architectures for networking. In the IETF, he mainly has been working on bringing Internet Technology to new links, applications, or radios. Since 2005, he has co-chaired, initiated, or co-authored many of the IETF efforts that now make up its Internet of Things (IoT) stack: he initiated the IETF work on Constrained RESTful Environments (CoRE) and the CoAP (Constrained Application) Protocol and co-chaired the IETF CoRE WG for its first ten years. Most recently, he launched the Thing-to-Thing Research Group (T2TRG) in the Internet Research Task Force (IRTF). He has authored and co-authored 48 Internet RFCs, which have 439 citations in other Internet RFCs.

Part 2: [Video] [Slides]

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.
