Network Virtualization:
– Definition: Abstracts network resources to create multiple independent virtual networks.
– Focus: Enhances resource utilization and security through network segmentation.
– Implementation: Uses hypervisors or virtual overlays like VXLAN, NVGRE.
Software-Defined Networking (SDN):
– Definition: Separates network control from data forwarding, enabling centralized management.
– Focus: Facilitates dynamic network configuration, automation, and programmability.
– Implementation: Uses software controllers (e.g., OpenFlow) to manage network devices.
Comparison:
– Network Virtualization: Creates virtual networks on top of physical infrastructure.
– SDN: Centralizes network management and enables programmable networks.
Both technologies modernize network operations, with network virtualization focusing on segmentation and resource optimization, while SDN enhances agility, automation, and centralized control.
