Network Design Overview

Designing an enterprise network is no different than designing any other system, such as complex software or advanced machinery. It hinges on fundamental engineering principles to balance availability, security, flexibility, and manageability. 

A campus LAN design isn't one-size-fits-all but ranges from small, single-switch setups to expansive, multi-building networks. The choice of platforms depends on capacity needs, device capabilities, and compliance requirements. 

While traditional multilayer designs are common, other options like virtualization or cloud outsourcing may better suit specific needs. Network architecture stems from thorough planning and design, requiring technical expertise. Decisions are driven by network analysis, focusing on quality, capacity, scalability, resiliency, and organizational requirements.
