The invention relates to a method of and to a system ( 1000 ) for dealing with network congestion. A first internet-working device ( 100 ) may have several paths available ( 110; 120 ) for accessing a second device ( 400 ) through a network (AN 1 ; AN 2 ). The first device may e.g. have a low-bandwidth connection that is always operational and/or a high-bandwidth connection which is only operational when the device in its docking station. The basic concept of the invention is embodied in a splitter/merger device ( 130 ) that proxies a connection ( 1 ), such as a TCP-connection, splits the connection ( 1 ) into multiple separate connections ( 2, 3 ) which are available, and routes packets ( 140 ) over these multiple connections to an external splitter/merger component ( 200 ). The splitter/merger device ( 130; 134; 142; 144; 152 ) divides the packets over the available connections in dependence of the progress of transport along each of these connections ( 2, 3 ). The functions of the splitter/merger components ( 130; 200 ) are symmetric and mirrored if there is both incoming ( 620; 140, 600 ) and outgoing ( 140; 500, 620 ) traffic.
