Trust by workflow in autonomic communication

Abstract

Autonomic network elements cooperate for media and media signalling delivery; the paper demonstrates how these nodes can elaborate significant trust and achieve self-organisation by the exchange of blueprints of their internal packet processing workflows. We outline a model of an etiquette for the above exchange under the governance of a locally computed community fitness. We concentrate on the etiquette design using extended protocol expressions as the notation for behaviours, and ad hoc communication example for the demonstration of design steps. We show that properly defined fitness can be used as a meta-rule modifying the etiquette towards wider or deeper trust within the community. © Springer-Verlag Berlin Heidelberg 2005.
