FBridge

FBridge is a type of network bridging technology that facilitates communication between different network segments. Its primary function is to connect two or more network interfaces, allowing them to act as a single, unified network. This enables devices on one segment to communicate with devices on another segment as if they were on the same physical network. FBridge typically operates at the data link layer of the OSI model.

The implementation of FBridge can vary, but it commonly involves software or hardware solutions. Software-based FBridge is often found in operating systems, enabling users to create virtual bridges between network adapters. This is particularly useful for virtual machines, allowing them to access the physical network or be isolated. Hardware-based FBridge is integrated into network devices like switches and routers, providing physical connectivity and traffic forwarding between ports.

Key benefits of using FBridge include simplifying network configurations, extending network reach, and enabling seamless connectivity for devices across different subnets or physical locations. It is a foundational technology for various networking scenarios, including creating robust local area networks, implementing network security policies, and facilitating the integration of diverse network devices.
