OVS

Open vSwitch (OVS) is an open-source software tool that creates virtual switches within computer networks. It enables multiple virtual machines or containers to communicate securely and efficiently over a shared physical network, much like a real-world switch connects multiple devices. OVS manages data traffic, enforces network policies, and supports advanced features like automation and network segmentation. It is widely used in data centers and cloud environments to improve network flexibility, scalability, and management, acting as a bridge that connects and controls virtual network connections just as a physical switch does for hardware devices.
