Generic Autonomic Signaling Protocol Application Program Interface
(GRASP API)
draft-ietf-anima-grasp-api-10
Abstract
This document is a conceptual outline of an application programming
interface (API) for the Generic Autonomic Signaling Protocol (GRASP).
Such an API is needed for Autonomic Service Agents (ASA) calling the
GRASP protocol module to exchange autonomic network messages with
other ASAs. Since GRASP is designed to support asynchronous
operations, the API will need to be adapted according to the support
for asynchronicity in various programming languages and operating
systems.

1. Introduction
As defined in [I-D.ietf-anima-reference-model], the Autonomic Service
Agent (ASA) is the atomic entity of an autonomic function, and it is
instantiated on autonomic nodes. These nodes are members of a secure
Autonomic Control Plane (ACP) such as defined by
