Description of Working Group:

  Low power and Lossy Networks (LLNs ) are made up of many embedded
  devices with limited power, memory, and processing resources. They are
  interconnected by a variety of links, such as IEEE 802.15.4, Bluetooth,
  Low Power WiFi, wired or other low power PLC (Powerline Communication)
  links. LLNs are transitioning to an end-to-end IP-based solution to
  avoid the problem of non-interoperable networks interconnected by
  protocol translation gateways and proxies.

  RFC7102 discusses ROLL specific aspects of LLNs, and RFC7228 provides
  additional terminology for constrained devices. RFC 5548, 5673, 5826,
  and 5876 describe the requirements for LLNs from several application

  The Working Group has focused on routing solutions for the areas:
  connected home, building, and urban sensor networks. It has developed a
  Framework that takes into consideration various aspects including high
  reliability in the presence of time varying loss characteristics and
  connectivity while permitting low-power operation with very modest
  memory and CPU pressure in networks potentially comprising a very large
  number (several thousands) of nodes.

  The Working Group continues to focus on routing issues for LLN and to
  maintain, improve and streamline the protocols already developed,
  including RPL and MPL. The focus is on IPv6 work only. The Working Group
  will pay particular attention to routing security and manageability
  (e.g., self-configuration) issues. The working group will consider the
  transport characteristics that routing protocol messages will

  ROLL will coordinate closely with the working groups in other areas that
  focus on constrained networks and/or constrained nodes, such as 6lo,
  6tisch, ipwave, lwig and CoRE. Other working groups such as pim, bier
  and manet will be consulted as needed. The Working group will align with
  the 6man WG when needed.

  Work Items are:

  - Guidance in using RFC6553, RFC6554, and IPv6-in-IPv6 encapsulation.

  - Additional protocol elements to reduce packet size and the amount of
    required routing states

  - Automatic selection of MPL forwarders to reduce message replication.

  - Data models for RPL and MPL management.

  - Multicast enhancements algorithms.
