 Host Identity Protocol-Based Overlay Networking Environment (HIP BONE)
  Instance Specification for REsource LOcation And Discovery (RELOAD)

Abstract

   This document is the HIP-Based Overlay Networking Environment (HIP
   BONE) instance specification for the REsource LOcation And Discovery
   (RELOAD) protocol.  The document provides the details needed to build
   a RELOAD-based overlay that uses HIP.

1.  Introduction

   The HIP-Based Overlay Networking Environment (HIP BONE) specification
   [RFC6079] provides a high-level framework for building HIP-based
   [RFC5201] overlays.  The HIP BONE framework does not address the
   specification of the details on how to combine a particular peer
   protocol with HIP to build an overlay.  It leaves this up to
   documents referred to as HIP BONE instance specifications.  As
   discussed in [RFC6079], a HIP BONE instance specification needs to
   define, minimally:

   o  the peer protocol to be used.

   o  what kind of Node IDs are used and how they are derived.

   o  which peer protocol primitives trigger HIP messages.

   o  how the overlay identifier is generated.

   This document addresses all the previous items and provides
   additional details needed to build RELOAD-based HIP BONEs, referred
   to here as RELOAD HIP BONEs.  The details on how different RELOAD
   modules would be integrated to a HIP implementation and what kind of
