             A Generic Autonomic Signaling Protocol (GRASP)
                       draft-ietf-anima-grasp-10

Abstract

   This document establishes requirements for a signaling protocol that
   enables autonomic nodes and autonomic service agents to dynamically
   discover peers, to synchronize state with them, and to negotiate
   parameter settings 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.
