Network Virtualization: Creating Logical Networks on a Physical Infrastructure Network virtualization is a revolutionary technology that enables the creation of multiple logical networks on a single physical infrastructure. By decoupling the logical network from the physical layer, organizations can achieve greater flexibility, scalability, and efficiency. This article explores the key concepts, benefits, and challenges of network virtualization. Understanding Network Virtualization Network virtualization involves the creation of virtual network devices, such as routers, switches, and firewalls, that operate independently within a physical network. These virtual devices are managed by a centralized controller, which allows for dynamic configuration and management of the logical network. Key Benefits of Network Virtualization Increased Flexibility: Network virtualization enables organizations to create and modify logical networks on demand, adapting to changing business needs and re
