This peer tag creates a tiny AS comprising a host and a + router linked by an up-link and a down-link (possibly asymmetrical). + This kind of pattern allows to easily build last-mile model style platforms. + Aggregating such patterns in a rule-based AS is thus the technique of + choice for modeling large peer-to-peer/volunteer computing/cloud platforms. + * New model for Vivaldi routing. We transformed the Vivaldi network model + into a Vivaldi routing model (based on the rule-based model).
