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.

   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.

   Naturally, an existing solution such as a secure file transfer
   protocol or secure HTTP might be used for this.  Other management
   protocols such as syslog [RFC5424] or NETCONF [RFC6241] might also be
   used for related purposes, or might be mapped directly over GRASP.
   The present document, however, applies to any scenario where it is
   preferable to re-use the autonomic networking infrastructure itself
   rather than an additional mechanism, but there is a need to transfer
   a large amount of data.  The basic model is to use the GRASP
