Abstract
A system and method for controlling data transmissions between a remote node and a local node of a computer communications network. The network has a plurality of nodes that are interconnected for the exchange of datagrams defining a plurality of virtual circuits. A plurality of physical data links connected to the local node are used to connect the local node to the network and an interface establishes a connection from the local node to the remote node via a first one of the links. The interface assigns one of the virtual circuits to the first link and assigns another one of the virtual circuits to a second one of the links. The local node receives the remote-to-local datagrams of the assigned virtual circuits via their respective links whereby the collective throughput requirement of the plurality of datagrams is distributed among the plurality of links thereby increasing the speed of data transmission between the remote node and the local node. Other features are also disclosed including correcting checksums in the datagrams.
