IIN extends intelligence across multiple products and infrastructure layers. IIN actively participates in the delivery of services and applications. Three phases in building an IIN are: –Integrated transport –Integrated services –Integrated applications

Cisco SONA brings several advantages to enterprises: –Outlines how enterprises can evolve toward the IIN –Illustrates how to build integrated systems across a fully converged intelligent network –Improves flexibility and increases efficiency

Cisco Enterprise Architectures with a hierarchical network model facilitate the deployment of converged networks. Converged networks with their traffic mix make higher demands on the network and its resources. Performance and security are key requirements in converged networks with wireless mobility.
