Link Aggregation Control (LAC) is a networking technique that combines multiple network connections into a single logical link. This approach enhances bandwidth and provides redundancy, ensuring that if one connection fails, the others can continue to carry traffic. LAC is commonly used in Ethernet networks to improve performance and reliability. The protocol that manages this process is known as the Link Aggregation Control Protocol (LACP). LACP allows devices, such as switches and routers, to automatically configure and maintain the aggregated links. By using LACP, network administrators can optimize data flow and reduce the risk of network downtime due to individual link failures.
