A Network Bridge is an essential networking device that helps connect two or more different network segments, allowing them to function as a single network. Think of it like a real-world bridge that connects two separate roads, enabling smooth traffic flow.
Network Bridges operate at the Data Link Layer (Layer 2) of the OSI model. Their main role is to filter, forward, and sometimes flood data packets between network segments based on MAC addresses. By doing so, they reduce unnecessary traffic and improve overall efficiency.
One of the key advantages of Network Bridges is that they help manage network congestion. 🖧 For example, if one segment of the network is overloaded, the bridge ensures that only the necessary traffic passes through to the other segment.
