1. A communications network for interactive communications among network users, comprising:

  • a network bus;

    a plurality of system nodes connected to the network bus with each system node having a loop delay associated therewith;

    a pacer connected to the network bus for providing timing signals thereon for synchronizing network bus access operations by the plurality of system nodes;

    an allocator that is capable of substantially simultaneously allocating the plurality of system nodes access to a network bus bandwidth by a plurality of bus allocation methods according to a network bus protocol that is based on the network bus being segmented in a time domain into repeating periods, compensation by each system node of its loop delay before accessing the network bus to transmit data during a repeating period, dynamically allocating access to the network bus bandwidth according to the plurality of bus allocation methods, and timing signals from the pacer, with at least one of the bus allocation methods being based on system nodes accessing the network bus bandwidth according to this method being given a requested discrete portion of network bus bandwidth for a predetermined number of repeating periods for transmitting data on the network bus.
