Open vSwitch (OVS) is a software-based virtual switch that can be used in virtualized environments, such as data centers and cloud computing. It allows network administrators to create virtual networks that are separate from the physical network infrastructure. OVS supports all popular tunneling protocols like VXLAN, GRE, Geneve, and STT, and provides advanced features like flow control, QoS, and network slicing. OVS is widely used in OpenStack, Kubernetes, and other container platforms to create and manage virtualized networking infrastructure.
