                  Information Distribution over GRASP
                 draft-liu-anima-grasp-distribution-04

Abstract

   This document discusses the requirement of information distribution
   capability in autonomic networks.  Ideally, the autonomic network
   should support distributing some information which is generated/
   injected at an arbitrary autonomic node and be distributed among the
   whole autonomic domain.  This docuemnt specifically proposes to
   achive this goal based on the GRASP (A Generic Autonomic Signaling
   Protocol), and specifies additional node behavior.

1.  Introduction

   In an autonomic network, sometimes the nodes need to share a set of
   common information.  One typical case is the Intent Distribution
   which is briefly discussed in Section 4.5 of
   [I-D.behringer-anima-reference-model].  However, the distribution
   should be a general function that one autonomic node should support,
