   Generic Autonomic Signaling Protocol Application Program Interface
                              (GRASP API)
                      draft-liu-anima-grasp-api-02

Abstract

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

1.  Introduction

   As defined in [I-D.ietf-anima-reference-model] , the Autonomic
   Serveice Agent (ASA) is the atomic entity of an autonomic function;
   and it is instantiated on autonomic nodes.  When ASAs communicate
   with each other, they should use the Generic Autonomic Signaling
   Protocol (GRASP) [I-D.ietf-anima-grasp].

   As the following figure shows, the GRASP could contain two major 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 functions based upon GRASP basic protocol.
   For example, [I-D.liu-anima-grasp-distribution] is one of the
   extended functions.

   It is desirable that ASAs can be designed as portable user-space
   programs using a portable API.  In many operating systems, the GRASP
   module will therefore be split into two layers, one being a library
   that provides the API and the other being kernel code containing
   common components such as multicast handling and the discovery cache.
