IPv6 over Networks of Resource-constrained Nodes (6lo) Internet Drafts

      
 IPv6 Neighbor Discovery Multicast and Anycast Address Listener Subscription

 Date: 16/04/2024
 Authors: Pascal Thubert
 Working Group: IPv6 over Networks of Resource-constrained Nodes (6lo)
 This document updates the 6LoWPAN extensions to IPv6 Neighbor Discovery (RFC 4861, RFC 8505) to enable a listener to subscribe to an IPv6 anycast or multicast address; the document updates RPL (RFC 6550, RFC 6553) to add a new Non-Storing Multicast Mode and a new support for anycast addresses in Storing and Non-Storing Modes. This document extends RFC 9010 to enable the 6LR to inject the anycast and multicast addresses in RPL.
 Transmission of SCHC-compressed packets over IEEE 802.15.4 networks

 Working Group: IPv6 over Networks of Resource-constrained Nodes (6lo)
 A framework called Static Context Header Compression and fragmentation (SCHC) has been designed with the primary goal of supporting IPv6 over Low Power Wide Area Network (LPWAN) technologies [RFC8724]. One of the SCHC components is a header compression mechanism. If used properly, SCHC header compression allows a greater compression ratio than that achievable with traditional 6LoWPAN header compression [RFC6282]. For this reason, it may make sense to use SCHC header compression in some 6LoWPAN environments, including IEEE 802.15.4 networks. This document specifies how a SCHC-compressed packet can be carried over IEEE 802.15.4 networks. The document also enables the transmission of SCHC-compressed UDP/ CoAP headers over 6LoWPAN-compressed IPv6 packets.
 Path-Aware Semantic Addressing (PASA) for Low power and Lossy Networks

 Working Group: IPv6 over Networks of Resource-constrained Nodes (6lo)
 This document specifies a topological addressing scheme, Path-Aware Semantic Addressing (PASA), that enables IP packet stateless forwarding. The forwarding decision is based solely on the destination address structure. This document focuses on carrying IP packets across an LLN (Low power and Lossy Network), in which the topology is static, the location of the nodes is fixed, and the connection between the nodes is also rather stable. This specifications describes the PASA architecture, along with PASA address allocation, forwarding mechanism, header format design, and IPv6 interconnection support.
 IPv6 Neighbor Discovery Prefix Registration
 
 draft-ietf-6lo-prefix-registration-02.txt
 Date: 13/02/2024
 Authors: Pascal Thubert
 Working Group: IPv6 over Networks of Resource-constrained Nodes (6lo)
 This document updates IPv6 Neighbor Discovery [RFC4861] and the 6LoWPAN extensions [RFC8505][RFC8928] to enable a node that owns or is directly connected to a prefix to register that prefix to neighbor routers. The registration indicates that the registered prefix can be reached via the advertising node without a loop. The prefix registration also provides a protocol-independent interface for the node to request neighbor router(s) to redistribute the prefix to the larger routing domain using their specific routing protocols. This document extends RPL [RFC6550][RFC6553][RFC9010] to enable the 6LR to inject the registered prefix in RPL.

Charter for Working Group

6lo focuses on the work that facilitates IPv6 connectivity over
constrained node networks with the characteristics of:
* limited power, memory and processing resources
* hard upper bounds on state, code space and processing cycles
* optimization of energy and network bandwidth usage
* lack of some layer 2 services like complete device connectivity and
broadcast/multicast

Specifically, 6lo will work on:

  1. IPv6-over-foo adaptation layer specifications using 6LoWPAN
    technologies (RFC4944, RFC6282, RFC6775) for link layer technologies of
    interest in constrained node networks

  2. Information and data models (e.g., MIB modules) for these
    adaptation layers for basic monitoring and troubleshooting.

  3. Specifications, such as low-complexity header compression, that are
    applicable to more than one adaptation layer specification

  4. Maintenance and informational documents required for the existing
    IETF specifications in this space.

Only specifications targeting constrained node networks are in scope.
6lo will work closely with the 6man working group, which will continue
to work on IP-over-foo documents outside the constrained node network
space and will continue to be the focal point for IPv6 maintenance. For
adaptation layer specifications that do not have implications on IPv6
architecture, 6man will be notified about 6lo's working group last call.
Specifications that might have such an impact (e.g., by using IPv6
addresses in a specific way or by introducing new ND options or by
exposing to IPv6 a link model different from either Ethernet or 6lowpan)
will be closely coordinated with 6man, and/or specific parts will be
fanned out to 6man documents. Beyond 6man, 6lo will also coordinate with
LWIG and INTAREA.

6lo works on small, focused pieces of work, but does not take on larger
cross-layer efforts. The working group will continue to reuse existing
protocols and mechanisms whenever reasonable and possible.

Security and management work that is not specific to the link layers
being worked on is out of scope. Work related to routing is out of
scope. 6lo will coordinate closely with the working groups in other
areas that focus on constrained node networks, such as ROLL (RTG) and
CoRE (APP).
