    摘要： Methods, systems and computer program products are provided which control message storms in a network by classifying multiple destination messages into a plurality of broadcast message classes based upon characteristics of the broadcast messages. The number of multiple destination messages for each class of broadcast messages of the plurality of classes of broadcast messages are then counted so as to provide a plurality of broadcast message class counts. Multiple destination messages of a class of broadcast messages are then selectively transmitted based upon the broadcast message class count for the class of broadcast messages.

    摘要： A method and system for systematically accessing and monitoring operating parameter signals within an IC device. A probe configuration logic selects a subset of signals from among a set of available signals within a physical or logical subdivision of the IC device. Signal access logic selectively provides physical or logical access from the selected subset of signals within the physical or logical subdivision of the IC device to a probe sensor, such that IC device operations may be flexibly and comprehensively monitored. A local mode selector provides remote access to the selected subset of signals at an input/output (I/O) data interface. Data packaging logic in communication with the probe sensor permits port mirroring of the I/O data interface.

    摘要： An apparatus for use in token ring switches for selectively setting the A/C bits in token ring frames. The apparatus includes a database with addresses of stations on the ring connected to the port. The apparatus compares the destination addresses of frames received from the ring with the addresses in the database and sets the A/C bits only if a match does not occur. By setting the A/C bits selectively, by the port, errors that would otherwise occur, either by setting the A/C bits on all frames or not setting the bits on all frames, are obviated.

    摘要： A method, apparatus and computer program product are provided for implementing a pointer and stake model for frame alteration code in a network processor. A current pointer and a stake are provided for a packet selected for transmit. The current pointer is maintained for tracking a current position for frame alteration operations in the packet. The stake is maintained for tracking a start of a current header for frame alteration operations in the packet. The current pointer is used by frame alteration code instructions to specify a sequence of operations relative to the current pointer. The specified frame alteration sequence is compact in terms of code size to operate on data within a small window of bytes. Advance pointer instructions allow the current and stake pointers to be advanced an arbitrary number of bytes into the packet.

    摘要： A design structure is provided for a slotted ring network, in which a node may transmit a non-renewable slot reservation with any unreserved slot. The reservation restricts other nodes from transmitting a new packet in the slot. When the slot returns around the ring to the reserving node, the slot will be available. Preferably, reservation is made responsive to a starvation condition in the reserving node, which may be detected in any of various ways. In an optional enhancement, a reservation identifies the reserving node, and another node on the ring is free to transmit a new packet in the reserved slot if the new packet will reach its destination at or before the reserving node, and thus will not interfere with the reservation.
