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.

In this session, we will provide an overview of how you can use IPv6 on AWS today – how to enable and migrate workloads at scale from IPv4-only to either dual-stack or IPv6-only architectures. We will cover the Amazon VPC IPv6 capabilities, how you can achieve IPv6 connectivity on AWS and hybrid network, and we’ll review common adoption patterns for hybrid connectivity, Internet-facing applications, and applications hosted on the edge. We’ll start with IPv6 address management on AWS using Amazon VPC IP Address Manager (IPAM) and take a step-by-step journey to an IPv6-enabled environment with Amazon VPC, peering, Transit Gateway and Cloud WAN, Direct Connect and VPN, are more.

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.

IPv6 ND was designed for P2P and transit subnetworks with cheap and reliable broadcast capabilities. This session will explain how this is unfit with IoT wireless operation, and explain the operation of SFAAC (stateful address autoconfiguration) that was introduced with 6LoWPAN ND.
The talk will discuss how SFAAC interacts with RPL and proxy ND to build scalable multi-link subnetworks, where the L3 concepts of Link and Subnet are not necessarily congruent with the layer 2 broadcast domain.

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.

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).

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.
