Network Virtualisation What is Network Virtualisation? Network virtualisation creates virtual versions of network resources, such as switches, routers, and connections, enabling multiple virtual networks to run on shared physical infrastructure. Explanation This technology enhances flexibility and scalability by allowing administrators to manage networks as software instead of physical devices. It is widely used in cloud environments. Practical Example of Network Virtualisation A data centre uses network virtualisation to allocate resources dynamically, supporting multiple clients with isolated virtual networks on shared hardware.
