What is Network Virtualization?
Network virtualization is a technique used to create multiple virtual networks on top of a single physical network infrastructure. It enables the abstraction of network resources, allowing users to provision, manage, and customize their own virtual networks independently of the underlying physical hardware. This can improve resource utilization, increase flexibility, and simplify network management.
Network virtualization involves creating multiple virtual networks on a single physical network infrastructure. It abstracts network resources, allowing for the provision, management, and customization of virtual networks independently of the underlying hardware. Key components include hypervisors or virtual switches, virtual network infrastructure (e.g., switches, routers, firewalls), and software-defined networking (SDN) for centralized control. Benefits include resource optimization, scalability, isolation, security, and flexibility. Common applications include data center virtualization, cloud computing, and enterprise networks.
