channel bonding

Channel bonding in computer networking is an arrangement in which two or more network interfaces on a host computer are combined for redundancy or increased throughput.On Ethernet interfaces, channel bonding requires assistance from both the Ethernet switch and the host computer's operating system, which must "stripe" the delivery of frames across the network interfaces in the same manner that I/O is striped across disks in a RAID array. For this reason, channel bonding is sometimes also called RAIN, or "redundant array of independent network interfaces".
