  Transferring Bulk Data over the GeneRic Autonomic Signaling Protocol
                                (GRASP)
                  draft-carpenter-anima-grasp-bulk-04

Abstract

   This document describes how bulk data may be transferred between
   Autonomic Service Agents via the GeneRic Autonomic Signaling Protocol
   (GRASP).  Although not an equivalent of a file transfer protocol,
   such a technique may be used for non-urgent transfer of data too
   large to fit into a normal GRASP message.

1.  Introduction

   The document [I-D.liu-anima-grasp-distribution] discusses how
   information may be distributed within the secure Autonomic Networking
   Infrastructure (ANI) [I-D.ietf-anima-reference-model].  Specifically,
   it describes using the Synchronization and Flood Synchronization
   mechanisms of the GeneRic Autonomic Signaling Protocol (GRASP)
   [I-D.ietf-anima-grasp] for this purpose.  However, those mechanisms
   are limited to distributing GRASP Objective Options contained in
   messages that cannot exceed the GRASP maximum message size of 2048
   bytes.  This places a limit on the size of data that can be
   transferred in a Synchronization or Flood operation.

   There are scenarios in autonomic networks where this restriction is a
   problem.  One example is the distribution of network policy in
   lengthy formats such as YANG or JSON.  Another case might be an
   Autonomic Service Agent (ASA) uploading a log file to the Network
   Operations Center (NOC).  A third case might be a supervisory system
   downloading a software upgrade to an autonomic node.  A related case
   might be installing the code of a new or updated ASA to a target node
   (see the discussion of ASA life cycles in
