摘要： A method and system for messaging between processors and co-processors connected through a bus. The method permits a multi-thread system processor to request the services of a processor or co-processor located on the bus. Message control blocks are stored in a memory which identify the physical address of the target processor, as well as a memory location in the memory dedicated to the thread requesting the service. When the system processor requests service of a processor or co-processor, a DCR command is created pointing to the message control block. A message is built from information contained in the message control block or transferred to the processor or co-processor. The return address for the processor or co-processor message is concatenated with the thread number, so that the processor or co-processor can create a return message specifically identifying memory space dedicated to the requesting thread for storage of the response message.

摘要： The decision within a packet processing device to transmit a newly arriving packet into a queue to await processing or to discard the same packet is made by a flow control method and system. The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to thresholds and also comparing present queue occupancy to previous queue occupancy. The outcome of the update is a new transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

摘要： A method for dynamically adjusting the flow rate of a plurality of logical pipes that share a common output queue. In accordance with the method of the present invention, a minimum flow rate and a maximum flow rate are set for each of the pipes. Next a determination is made of whether or not excess queue bandwidth exists in accordance with the output flow rate of the shared queue. The determination of whether or not excess bandwidth exists comprises comparing the output flow rate of the shared queue with a pre-determined threshold queue output value. An instantaneous excess bandwidth signal has a value of 1 if there is excess bandwidth and is otherwise 0 if there is no excess bandwidth. In an alternate embodiment, the instantaneous excess bandwidth signal for a particular pipe is logically ANDed with one or more additional excess bandwidth signals to form a composite instantaneous excess bandwidth signal. In response to the existence of excess queue bandwidth, a flow rate of a pipe is linearly increased while in response to a lack of excess queue bandwidth, the flow rate of the pipe is exponentially decreased.

摘要： A technique for maintaining input/output (I/O) command ordering on a bus includes assigning a channel identifier to I/O commands of an I/O stream. In this case, the channel identifier indicates the I/O commands belong to the I/O stream. A command location indicator is assigned to each of the I/O commands. The command location indicator provides an indication of which one of the I/O commands is a start command in the I/O stream and which of the I/O commands are continue commands in the I/O stream. The I/O commands are issued in a desired completion order. When a first one of the I/O commands does not complete successfully, the I/O commands in the I/O stream are reissued on the bus starting at the first one of the I/O commands that did not complete successfully.

摘要： A method and system for transmitting packets in a packet switching network. Packets received by a packet processor may be prioritized based on the urgency to process them. Packets that are urgent to be processed may be referred to as real-time packets. Packets that are not urgent to be processed may be referred to as non-real-time packets. Real-time packets have a higher priority to be processed than non-real-time packets. A real-time packet may either be discarded or transmitted into a real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time queue congestion conditions. A non-real-time packet may either be discarded or transmitted into a non-real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time and non-real-time queue congestion conditions.

摘要： In an ordered semaphore management system a pending state allows threads not competing for a locked semaphore to bypass one or more threads waiting for the same locked semaphore. The number of pending levels determines the number of consecutive threads vying for the same locked semaphore which can be bypassed. When more than one level is provided the pending levels are prioritized in the queued order.

摘要： In a slotted ring network, 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.

摘要： A method and system for controlling a plurality of pipes in a computer network is disclosed. The computer network includes at least one processor for a switch. The at least one processor has a queue. The plurality of pipes utilizes the queue for transmitting traffic through the switch. The method and system include allowing a minimum flow and a maximum flow to be set for each of the plurality of pipes and determining if excess bandwidth exists for the queue. The method and system also include linearly increasing a flow for a pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth exists and if the flow for the pipe of the plurality of pipes is less than the maximum flow for the pipe. The method and system also include exponentially decreasing the flow for the pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth does not exist and the flow is greater than the minimum flow for the pipe. Thus, the traffic through the queue is stable.
