             A Generic Autonomic Signaling Protocol (GRASP)
                       draft-ietf-anima-grasp-00

Abstract

   This document establishes requirements for a signaling protocol that
   enables autonomic devices and autonomic service agents to dynamically
   discover peers, to synchronize state with them, and to negotiate
   parameter settings mutually with them.  The document then defines a
   general protocol for discovery, synchronization and negotiation,
   while the technical objectives for specific scenarios are to be
   described in separate documents.  An Appendix briefly discusses
   existing protocols with comparable features.
