Network Design Link

Using VLANs to isolate sensitive departments (like Finance or R&D) from the rest of the network. This prevents "lateral movement" if one device is compromised.

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. network design

We are moving away from purely hardware-centric designs toward . SD-WAN allows companies to manage their network via software, automatically routing traffic over the most efficient path (e.g., using a cheap internet connection for basic apps and a private line for critical data). Additionally, "Hybrid" designs now integrate local office hardware seamlessly with cloud providers like AWS or Azure, treating the cloud as an extension of the local data centre. Conclusion Using VLANs to isolate sensitive departments (like Finance

Not all data is equal. A good design prioritizes time-sensitive traffic—like Voice over IP (VoIP) or video conferencing—over standard web browsing to ensure clear communication. 3. Security by Design This involves using modular hardware and a structured

A solid network design is invisible when it works well. By adhering to a hierarchical structure, ensuring no single point of failure, and embedding security into the very fabric of the architecture, an organization creates a platform that can support the heavy demands of modern digital business.

High availability is non-negotiable. Designers use dual-homing (connecting a switch to two upstream devices) and protocols like STP (Spanning Tree Protocol) or LACP (Link Aggregation Control Protocol) to ensure that if one cable or switch fails, the network stays live.
