             A Generic Autonomic Signaling Protocol (GRASP)
                       draft-ietf-anima-grasp-14

Abstract

   This document specifies the GeneRic Autonomic Signaling Protocol
   (GRASP), which enables autonomic nodes and autonomic service agents
   to dynamically discover peers, to synchronize state with each other,
   and to negotiate parameter settings with each other.  GRASP depends
   on an external security environment that is described elsewhere.  The
   technical objectives and parameters for specific application
   scenarios are to be described in separate documents.  Appendices
   briefly discuss requirements for the protocol and existing protocols
   with comparable features.
