A method for controlling communication between a hub and a plurality of distributed stations over a medium is disclosed. The method comprising the steps of a method for controlling communications access between a hub () and a plurality of distributed stations (M-M) over a medium, the method comprising the steps of (a) allocating a plurality of channels for data communications between the station (M-M) and the hub (), the number of channels being at least equal to the number of stations, (M-M) and each station owning at cast one channel, each channel being varyingly in one of an empty-, a reserved, or an owner-state, and whereby (i) the empty-state provides a channel to which any station (M-M) can have access; (ii) the reserved-state provides a channel to which a station (M-M) having made a reservation with the hub (), but not owning the channel, can have access; and (iii) the owner-state provides a channel to which only the owning station (M-M) has access; and (b) allocating the respective state and/or the number of channels over time an the basis of each station's data requirements.
