         Terms Used in Routing for Low-Power and Lossy Networks

Abstract

   This document provides a glossary of terminology used in routing
   requirements and solutions for networks referred to as Low-Power and
   Lossy Networks (LLNs).  An LLN is typically composed of many embedded
   devices with limited power, memory, and processing resources
   interconnected by a variety of links.  There is a wide scope of
   application areas for LLNs, including industrial monitoring, building
   automation (e.g., heating, ventilation, air conditioning, lighting,
   access control, fire), connected home, health care, environmental
   monitoring, urban sensor networks, energy management, assets
   tracking, and refrigeration.

1.  Introduction

   This document provides a glossary of terminology used in routing
   requirements and solutions for networks referred to as Low-Power and
   Lossy Networks (LLNs).

   LLNs are typically composed of many embedded devices with limited
   power, memory, and processing resources interconnected by a variety
   of links, such as IEEE 802.15.4 or low-power Wi-Fi.  There is a wide
   scope of application areas for LLNs, including industrial monitoring,
   building automation (heating, ventilation, air conditioning,
   lighting, access control, fire), connected home, health care,
   environmental monitoring, urban sensor networks, energy management,
   assets tracking, and refrigeration.

   Since these applications are usually highly specific (for example,
   industrial automation, building automation, etc.), it is not uncommon
   to see a number of disparate terms used to describe the same device
   or functionality.  Thus, in order to avoid confusion or
   discrepancies, this document specifies the common terminology to be
   used in all ROLL working group documents.  The terms defined in this
   document are used in [RFC5548], [RFC5673], [RFC5826], and [RFC5867].

   Terminology specific to a particular application is out of the scope
   of this document.

RFC 7102                    LLN Routing Terms               January 2014

   It is expected that all routing documents defining requirements or
   specifying solutions for LLN will use the common terminology
   specified in this document.  This document should be listed as an
   informative reference.

   Actuator: A field device that controls a set of equipment.  For
      example, an actuator might control and/or modulate the flow of a
