Link Aggregation Control Protocol (LACP) is a network protocol that allows multiple physical network connections to be combined into a single logical link. This aggregation increases bandwidth and provides redundancy, ensuring that if one connection fails, the others can continue to carry traffic without interruption. LACP is part of the IEEE 802.3ad standard and is commonly used in Ethernet networks. It helps manage the grouped links by dynamically configuring and monitoring the connections, making it easier to balance network traffic and improve overall performance.
