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.
