In computer networking, the term link aggregation applies to various methods of combining (aggregating) multiple network connections in parallel in order to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the links should fail A link aggregation group (LAG) combines a number of physical ports together to make a single high-bandwidth data path, so as to implement the traffic load sharing among the member ports in the group and to enhance the connection reliability Other umbrella terms used to describe the method include port trunking, link bundling, Ethernet/network/NIC bonding, channel bonding, port channeling or NIC teaming
