The aim of the invention is to convectively move at least one liquid in a channel of a microsystem which comprises a predetermined channel direction. A ribbon of labels has a plurality of labels and a cavity formed in each of the labels. The multiplex invoker is to form a socket on the remoting client, to bind the socket to a port of the remoting client, to couple the socket to a socket of a remoting server, to form a plurality of virtual sockets on the remoting client, and to associate the plurality of virtual sockets with the socket of the remoting client.
