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

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.

IPAM usage for IPv6

IP address Management (IPAM) is a critical tool of modern enterprise networks. IPAM not being a set Standard means there is a lot to consider when choosing an IPAM strategy and tool.  IPv6 can present challenges due to its sheer scale of available IP Addresses. We will walk through features that can make this a seamless process and how tools can dramatically improve our IPAM solution's accuracy and depth of information. We will finish up with a  dive into the role our IPAM solution plays in overall enterprise security.

Robert Nagy came to the world of technology with a long history as a corporate trainer and has been providing Professional Services and Network Training since 2000. He began his Technology Career providing all aspects of Design, Architecture and Implementation for Networking events around the country including:

* Microsoft/Global Briefing
* Microsoft/Professional Developers Conference
* Keynote Addresses of MacWorld
* Sun/Java One
* Sun/Networkers
* Cisco/Networkers

Rob credits the ever changing requirements, products demanded for networking events, and his work as a volunteer on the InterOp and IETF Network teams, as having given him a deep knowledge base in a broad spectrum of networking technologies. After leaving the world of professional event networking, Robert went on to work as a Professional Services Engineer for Infoblox, followed by a role as the Senior Network Engineer for Shutterfly, and then on to working as a Principal Security Consultant for Accuvant Inc.

Robert saw the need for an independent consulting company that did not compete for hardware sales, but rather focused on quality, comprehensive professional services and technical training development and delivery. This directive lead Robert to begin DeepDive Networking in 2008.

DHCP is so much more than assigning an IP address in our modern network environments. When moving to IPv6, this means we have a lot to consider and address.

  • What are the common DHCP issues and considerations encountered when migrating to IPv6?

  • How do we deal with the internet differences in DHCP in IPv4 versus IPv6?

  • How about changes to much used features like DHCP failover and DHCP fingerprinting?

Finally we will look at DHCP's value in Network Security and how it can be an important part of your network security solution.

DNS is often an overlooked aspect of any network environment. When moving to IPv6, this is an important aspect that must be planned for and addressed.

  • What are the common DNS issues encountered when migrating to IPv6?

  • What changes are needed to DNS? 

  • How can DNS assist in the move to IPv6?

We will dive into DNS and its relationship with implementing IPv6 in your environment.

Getting Started with IPv6 on the Mainframe

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.
