Chapter 1. Strategic Network Design
This section introduces you to the Cisco Service-Oriented Network Architecture (SONA) framework for network design. In addition, you learn how to examine characteristics of an existing network, while determining design requirements. Finally, this section discusses Cisco’s top-down approach to network design.
Cisco Service-Oriented Network Architecture
Cisco recently updated its Architecture for Voice Video and Integrated Data (AVVID) design approach to the Intelligent Information Network (IIN). IIN is a complete architecture that is more all encompassing than AVVID.
The three phases of constructing an IIN are as follows:
• Integrated transport—Voice, data, and video are all converged onto a single transport. ...
