What technology allows the merging of multiple links into a single logical link?

Link aggregation is a technology that enables the combination of multiple physical network links into a single logical link. This is primarily achieved through protocols such as Link Aggregation Control Protocol (LACP), which facilitates the management of multiple connections and ensures they work together seamlessly.

By aggregating links, organizations can improve bandwidth availability, enhance fault tolerance, and provide redundancy. If one link in the aggregated group fails, the traffic can continue to flow over the remaining operational links without interruption. Additionally, link aggregation can help in optimizing network performance as it balances traffic load across the multiple links, preventing any single link from becoming a bottleneck.

This approach is commonly used in environments that require high throughput and reliability, making it an essential component in network design and performance optimization.
