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.

[ What is claimed is:] [1.] A method of controlling data transmissions between a remote node and a local node of a computer communications network, said network having a plurality of nodes interconnected for the exchange of datagrams, said local node having a plurality of physical data links connected thereto for connecting the local node to the network, said datagrams defining a plurality of virtual circuits between the local node and the remote node, each datagram including either source or destination address data corresponding to one of the links, each virtual circuit being defined by at least one local-to-remote datagram and at least one remote to local datagram, said method comprising the steps of:establishing a connection from the local node to the remote node via a first one of the links;assigning one of the virtual circuits to the first link;assigning another one of the virtual circuits to a second one of the links, said step of assigning the virtual circuit to the second link including altering the address data at the local node in each of the datagrams that define the virtual circuit assigned to the second link so that the address data corresponds to the second link rather than to the first link; andreceiving 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.
