Initial Analysis on Intelligence Mechanisms of Reconfigurable Network Abstract Flexibility,with which a reconfigurable network adaptively tunes its structure,plays a critical role in accommodating varieties of applications with desirable service levels.Most studies avalaible,however,rarely provide clear answers about the mechanism of flexibility that supports network reconfigurations.For the mechanism more clear,this paper clarifies a key target of the consistant matching of service outcomes to application demands.What is then revealed includes the kernal characteristic,so-called outcome following demand with gardually tuning,of the reconfiguration flexibility.Furthermore,four inherent schemes and frameworks representing reconfiguration flexibility are respectively examined in depth.They are the knowledeg-driven architecture of network functionalities,cross-layer interactions of functionalities,distributed and collaborative sensing,and distributed intelligece.Finally,the method of ant conoly optimization（ACO）is emphasized by explaining its effectiveness in optimizing non-linear problems such as performence-constrained routing at small time scales.Specifically,both the advantage and significance of emergence,the prominent feature of ACO,are illustrated.
