            Information Distribution in Autonomic Networking
                 draft-liu-anima-grasp-distribution-11

Abstract

   This document discusses the requirement to autonomic nodes supporting
   information distribution based over GRASP in autonomic networks. In
   general, information distribution can be categorized into two
   different modes: 1) one autonomic node instantly sends information to
   other nodes in the domain; 2) one autonomic node publishes some
   information and asynchronously some other interested nodes request
   the published information. In the former case, information data will
   be generated and consumed instantly. In the latter case, information
   data live longer in the network.

   These capabilities are basic and fundamental to an autonomous network
   system (i.e. ANI [I-D.ietf-anima-reference-model]). This document
   clarifies possible use cases of information distribution in ANI and
   requirements to ANI so that rich information distribution can be
   natively supported. Extensions to autonomic nodes are proposed and
   detailed embodiments based on GRASP are discussed.
