摘要： A repeater interface controller receives a data packet at one of a plurality of port nodes from an associated segment of a local area network. The plurality of port nodes determine a priority port node when more than one port node receives a data packet at substantially the same time. The priority port node transmits the data packet from the priority port node to a central node. The central node receives the data packet from the priority node, repeats the data packet, and transmits the repeated data packet to the non-priority port nodes. Each non-priority port node receives the repeated data packet and transmits the repeated data onto its associated segment. Management and status information is transferred between the port nodes and an external processor and an external display by an internal bus and an external bus. A bus arbiter alternately provides a bus controller and the external controller control of both the internal and external buses to transfer the data. The bus controller controls both the internal and external buses when management and status data is transferred from the port nodes to the external display and the external controller controls both buses when management and status information is transferred between the external controller and the port nodes.

摘要： A repeater interface controller receives a data packet at one of a plurality of port nodes from an associated segment of a local area network. The port nodes determine a priority port node, if more than one port node receives a data packet at substantially the same time, and transmit the data packet from the priority port node to a central node. The central node receives the data packet, repeats the data packet from the priority node, and transmits the repeated data packet to the non-priority port nodes. Each non-priority port node receives the repeated data packet and transmits the repeated data onto its associated segment. Each port node further includes a partitioning port state machine which monitors its associated segment and partitions the segment from the repeater interface controller when the partitioning port state machine detects a collision in a predetermined number of consecutive data packets. The partitioning port state machine detects collisions in each packet from a beginning of the data packet until an end of the data packet.

摘要： The present invention is directed to various features of a repeater interface controller (RIC) that connects segments of a bus/tree local area network. In the described embodiment of the invention, the RIC implements the IEEE 802.3 repeater specification.In accordance with another aspect of the present invention, the RIC provides hub management support in the form of information regarding the status of its ports and of the packets it is repeating. This data is available in three forms: counted events, recorded events and status packets. This information is available through the RIC's interface. The counters and event recording registers have user-definable masks which enable them to be configured to count and record a variety of events.In accordance with another aspect of the present invention, the RIC management statistics at maximum network bandwidth. Statistics are logged while a packet repetition is in process and are furnished to counter and flag arrays after transmission of the same packet has ended. The independent operations of logging and furnishing the information allows management statistics gathering of successive packets with minimal interframe gaps.

摘要： The nodes of a repeater interface controller which repeats data packets received from one segment of a local area network onto the remaining segments of the local area network include loopback circuitry that allow the data packets received from the one segment to be repeated back onto the one segment in addition to the remaining segments of the local area network, thereby allowing the integrity of the one segment to be verified.
