Network Design 【2026】

A "solid" design anticipates growth. This involves using modular hardware and a structured IP addressing scheme (IPv6 or CIDR) that allows for easy expansion without reconfiguring the entire system.

Most modern network designs follow the (Cisco’s classic hierarchy), which prevents a single device from becoming a bottleneck: network design

The "highway" of the network. Its sole purpose is to switch traffic as fast as possible. It avoids complex packet manipulation to maintain maximum speed. A "solid" design anticipates growth

The "driveways." This is where end-user devices (PCs, printers, Wi-Fi APs) connect. It focuses on port security and providing power (PoE) to devices. 2. Core Principles: Performance and Reliability network design
