What is an Ethernet Bridge and How Does it Work?
An Ethernet bridge is a device or software that connects two or more Ethernet networks together, allowing them to communicate with each other as if they were a single network. It works by examining the source and destination addresses of incoming Ethernet frames and forwarding them to the appropriate network. This process is transparent to the devices on the networks, which do not need to be aware of the bridge’s presence. The bridge learns the addresses of devices on each network and builds a table of these addresses, which it uses to forward frames.
The Ethernet bridge operates at the data link layer of the OSI model, which means it does not examine the contents of the frames it forwards, only their addresses. This makes it a relatively simple and efficient device compared to routers, which operate at the network layer and need to examine the contents of packets to determine where to forward them. Ethernet bridges are commonly used to connect networks in different buildings or to connect a wireless network to a wired network. They are also used in network virtualization, where they are used to connect virtual networks together.
