The load sharing driver tries to distribute the outgoing IP packets over these lines in a method which tries to maximize the utiltization of each line; essentially a round robin when all of the packets are the same (maximum) size. This allows you to get effective throughput close to the sum of the baudrate of all lines used, and to continue to send packets as long as at least one of the lines is operating. Routing is still done on a per-interface basis; all of the load-shared lines use the same IP network interface for transmission of packets. In contrast, if you used an IP interface per line between two nodes, only one of the lines would be used at any time by routing algorithm provided in standard 4BSD software.
