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.
