Designing for Cisco®
Internetwork Solutions (DESGN) Version 3.0 is a Cisco Training on Demand course. It introduces you to general approaches and technologies for network design and promotes Cisco solutions in designing and implementing scalable internetworks.

You gain information on the modular approaches to network design and dividing networks into access, distribution, and core layers only and separately for the campus and the WAN module. You learn how to use the Enterprise Composite Model to facilitate planning, designing, implementing, operating, and optimizing (PDIOO) networks by focusing on a certain module and on relations between the modules.

Most network solutions today (for example, voice, video, storage networking, and content networking) are typically overlay solutions spanning several modules, so the composite modular approach is even more relevant and is the main focus of this course. Services virtualization and the Cisco Service-Oriented Network Architecture (SONA) are also described.
