Abstract
A variety of detailed technologies, concepts, and models aim at the realization of intelligent integrated networks and services. Active and programmable networking enable the introduction of new network services by adding dynamic programmability to network devices and making aspects of the programmability accessible to third-party vendors and users via open interfaces. Open and programmable network elements help redefine network software architectures and move control and management systems away from traditional closed and rigid solutions, bringing us one step closer to an environment where all devices and services seamlessly interoperate and cooperate with each other. Computational intelligence (CI) has emerged through a vivid and diversified synergy of technologies of granular computing, neural networks, and evolutionary computing. Each of the contributing technologies there plays an important and unique role. In essence, we can state that CI is a manifestation and implementation of a general design methodology applied to complex systems. The article reviews this special issue.
