Briefly, in accordance with one embodiment of the invention, an extendible local area network includes a hub station including a memory and at least one hub station segment. The hub station segment is adapted to be coupled to at least N other hub station segments by a bi-directional control signal bus, N being a positive integer. The hub station segment includes at least two ports, each of the ports being adapted to receive electrical signal packet transmissions from a remote station. The memory and the hub station segment are mutually coupled by a signal bus. Likewise, a method of transmitting electrical signal packets in a hub station of an extendible local area hub network includes the steps of: receiving at least one electrical signal packet at one of the ports of one of the hub station segments in the hub station from a remote station directly coupled to the one hub station segment, transmitting the at least one packet to the memory from the one hub station segment, and receiving the at least one packet at any other hub station segment substantially concurrently with the transmission to the memory, at least if the at least one packet constitutes a unicast packet.
