                      draft-liu-anima-grasp-api-00

Abstract

   This document specifies the application program interface of the
   Generic Autonomic Signaling Protocol (GRASP).  The API is used for
   Autonomic Service Agent (ASA) calling the GRASP protocol module to
   communicate the autonomic network signalings with other ASAs.

1.  Introduction

   As defined in [I-D.ietf-anima-reference-model] , ASA is the atomic
   entities of an autonomic function; and it is instantiated on
   autonomic nodes.  When ASAs communicate with each other, they should
   use the GRASP [I-D.ietf-anima-grasp].

   As the following figure shows, the GRASP could contain two sub-
   layers.  The bottom is the GRASP base protocol module, which is only
   responsible for sending and recieving GRASP messages.  The upper
   layer is some extended funcitons based upon GRASP basic protocol.
   For example, [I-D.liu-anima-grasp-distribution] is one of the
   extended functions.
