Link Aggregation

Link aggregation is a networking technique that combines multiple physical connections between devices into a single, logical connection. This increases bandwidth—allowing more data to flow simultaneously—and provides redundancy; if one link fails, others continue to carry the traffic. Think of it like multiple lanes on a highway: more lanes mean more cars can travel at once, reducing congestion and improving reliability. It’s commonly used in data centers and enterprise networks to enhance performance and ensure continuous connectivity without needing additional single connections.
