When designing your network architecture, you should consider some general principles to ensure reliability, security, and efficiency. Modularity involves dividing your network into smaller, manageable units with clear functions and boundaries. Hierarchy organizes the network into layers with distinct roles and responsibilities. Redundancy provides backup or alternative paths, devices, or links in case of failure or overload. Lastly, security applies measures such as encryption, authentication, firewalls, VPNs, or IDS/IPS to protect the network from unauthorized access or attack. By following these principles, you can isolate faults, simplify troubleshooting, enhance security, scale your network, control traffic flow, reduce congestion, improve performance, increase availability and fault tolerance of your network, and safeguard your data and resources.
