Link Aggregation is a networking technique that combines multiple network connections into a single logical link. This approach increases bandwidth and provides redundancy, ensuring that if one connection fails, the others can still maintain the network's performance. It is commonly used in Ethernet networks to enhance data transfer rates and improve reliability. The most widely used standard for Link Aggregation is defined by the IEEE 802.3ad protocol, which allows devices like switches and routers to group several physical links. This grouping helps balance network traffic and optimizes resource usage, making it an essential feature for businesses that require stable and fast network connections.
