            Information Distribution in Autonomic Networking
                 draft-liu-anima-grasp-distribution-10

Abstract

   This document discusses the requirement of capability of information
   distribution among autonomic nodes 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. Possible options to realize the information
   distribution function are also briefly discussed.

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF), its areas, and its working groups.  Note that
   other groups may also distribute working documents as
   Internet-Drafts.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
