Abstract:
1. A switched Local Area Network (LAN) structure, comprising: a plurality of active LAN switches that generate and transmit Protocol Data Units (PDUs); a plurality of passive end stations that only transmit response PDUs in response to receiving PDUs from the active LAN switches; and a plurality of Ethernet links connecting the active LAN switches and the passive end stations; wherein each of the active LAN switches and the passive end stations include: wherein each of the active LAN switches includes means for controlling for each of its ports, whether or not a particular end station connected at the far end of a corresponding Ethernet link, is allowed to transmit traffic flows towards the active LAN switch through the corresponding Ethernet link, by modifying an interval with which the active LAN switch generates and transmits PDUs toward the particular end station.
