Course Overview
In addition to general approaches and technologies for network design, this course promotes Cisco solutions in designing and implementing scalable internetworks. Among specific goals is the promotion of the modular approach to network design.

The Enterprise Composite Model facilitates planning, designing, implementing, operating and optimizing (PDIOO) networks by concentration on a certain module and on relations between the modules. Taking into account that most network solutions today (e.g. voice, video, storage networking, content networking) are typically overlay solutions spanning several modules, the composite modular approach seems even more relevant and is the main focus of this course. In addition, services virtualization and the SONA architecture are presented.
