Examine how Designing for Cisco Internetwork Solutions (DESGN) Course Version 1.2 is almost identical with Version 1.1 in addition to general approaches and technologies for network design that promotes Cisco solutions in designing and implementing scalable internetworks. Among specific goals to promote the new modular approach to network design has been intuitively used for the last few years and Cisco now wants to formalize. The early modular approach to network design divided networks into access, distribution, and core layers only: separately for the campus and the Wide Area Network (WAN) part. The new Enterprise Composite Model facilitates designing, planning, implementing, operating and troubleshooting (PDIOT) 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, which the composite modular approach seems even more relevant and is the main focus of this course. |
