In a network communications system, a user device (70) includes a communications subsystem operable to establish communications with selected servers (72, 74, 90, 92) of the system. Also included are domain master stations (82, 84) connected to monitor communications traffic loading at each of a respective group of servers. In order to avoid traffic overcrowding at individual servers, a redirector station (78) is provided coupled with the domain master stations and accessible by the user device (70). The redirector station is arranged to select an optimum server (74) to handle communications of a user device on the basis of both the physical location of that server relative to the user device and its current communications traffic loading and, having made its selection, it instructs the user device to re-establish network communications via the selected server.
