    摘要: A method and apparatus for securing a network from access by unauthorized end stations. A port in a multiport repeater can be disabled automatically upon detection of an unknown source address in a data packet. In addition, an interrupt signal is provided to the indicate the detection of an intruder. Further, the disabling of the port can be done substantially immediately to interrupt the re-transmission of a single packet. Alternatively, the disabling of a port can be done programmably after a predetermined number of intruder packets have been detected, or after the verification of packet integrity.

    摘要: A method and apparatus for efficiently transferring a data packet on a network. The efficient transfer of data includes compressing the data as the data packet is transmitted from a repeater to a management unit by determining if a destination address of a received packet matches a stored management unit address. When the stored address does not match the destination address, the data packet is compressed. The apparatus includes a repeater, a management unit, and a packet compression mechanism. The apparatus further includes comparator circuit means for determining address comparisons and count comparisons to control data compression.

    摘要: A method for providing a secure local area network includes the steps of receiving a data packet having a destination address and comparing the destination address to stored end station addresses. The data packet is disrupted on the repeater for the ports except the port with an associated stored end station address matching the destination address. Also, the disrupting of the data packet can be enabled on an individual port basis. A system includes a controller, a memory/comparator, and an inverse disrupt control mechanism. The inverse disrupt control mechanism produces a disrupt signal to disrupt the data packet on non-matching ports of the repeater when a match occurs within the repeater. The data packet is not disrupted on a port linking two repeaters when there is no match within the repeater. The inverse disrupt control can also be enabled or disabled on an individual port basis.

    摘要: Systems, methods, and other embodiments associated with auto-negotiating over a single pair PHY are described. According to one embodiment, an apparatus includes a physical layer (PHY) transceiver configured to communicate over a single twisted pair channel. The apparatus includes a setup logic configured to control the PHY transceiver to initiate an auto-negotiation sequence over the single twisted pair channel with a remote device upon detecting a transmission from the remote device on the single twisted pair channel. The auto-negotiation sequence includes an exchange of parameters with the remote device using a half-duplex mode to communicate on the single twisted pair channel.
