Network Design Today

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

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

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 We are moving away from purely hardware-centric designs

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. Conclusion Most modern network designs follow the (Cisco’s

Implementing Next-Generation Firewalls (NGFW) and Intrusion Prevention Systems (IPS) at the boundary between the internal network and the internet. 4. Modern Evolution: SD-WAN and Cloud
