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

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

Cisco Enterprise Architecture with a hierarchical network model facilitates the deployment of converged networks. There are two typical types of remote locations: branch office and SOHO site. Several different possibilities exist as to how to connect remote locations with the central site: IPsec VPNs, MPLS VPNs, DSL, or cable.
