When planning a network, it is important to follow key design policies to ensure the network is secure, reliable, and ready for growth. One important policy is security, which protects the network from threats by controlling access to data and devices. This includes using firewalls, strong passwords, and encryption to keep hackers and viruses out. Another key policy is the performance policy, which helps the network run smoothly by making sure there is enough bandwidth and the right placement of network devices like routers and switches. This prevents slow connections and system failures.
The scalability policy ensures the network can grow in the future without needing a full redesign. It allows more users, devices, or data to be added as needed. By following these three policies—security, performance, and scalability—network planners can create a strong, efficient, and flexible network that meets both current and future needs.
