Information Distribution over GRASP
draft-ietf-anima-grasp-distribution-00
Abstract
This document proposes a solution for information distribution in
autonomic networks. Information distribution is categorized into two
different modes: 1) instantaneous distribution; 2) publication for
retrieval. In the former case, the information is sent, propagates
and is disposed of after reception. In the latter case, information
needs to be stored in the network.
The capabilities to distribute information are basic and fundamental
needs for an autonomous network ([RFC7575]). This document describes
typical use cases of information distribution in ANI and requirements
to ANI, such that rich information distribution can be natively
supported. The document proposes extensions to the autonomic nodes
and suggests an implementation based on GRASP
([I-D.ietf-anima-grasp]) extensions as a protocol on the wire.
