CHAPTER 1 Hierarchical Network DesignObjectivesUpon completion of this chapter What are the structured engineering prin-ciples of Network Design ? How do you apply the three Hierarchical net-work layers in Network Design ? What are the four basic modules in an enter-prise campus Network architecture that inter-connect via the core? How do the modules of the Cisco Enterprise Architecture model differ? What are some trends that are challenging enterprise Network architectures? How do the Borderless Network , Collaboration Network , and Data Center/Virtualization Network architectures address the Network challenges?
Hierarchical Network Design Overview (1.1) The Cisco hierarchical (three-layer) internetworking model is an industry wide adopt-ed model for designing a reliable, scalable, and cost-efficient internetwork. In this section, you will learn about the access, distribution, and core layers and their role in the hierarchical network model.
