摘要： A virtual to physical address translator in which a requesting process supplements a virtual memory address with a shortcut to a physical address associated with one level of a multi-level virtual address translation table. A second process, such as an I/O process, receives the shortcut and the virtual address and uses an address translator to determine the physical address. In some implementations, the shortcut may be made opaque to the requesting process such that the requesting process cannot determine the physical address represented in the shortcut.

摘要： A source node receives related frames of data to be transmitted from the source node to a destination node and places the frames in a queue. The queue is associated with a communication path over which the related frames are to be transmitted to the destination node. An interface that couples the source node to the communication path receives an indication directed to the source node of traffic congestion in the communication path. In response, the source node controls the rate at which the related frames of data are transferred from the queue to a transmit buffer accessible to the interface, in order to relieve the traffic congestion in the communication path.

摘要： According to one embodiment of the invention, a method comprises measuring traffic congestion experienced by a message transmitted from a source device, and if the measured traffic congestion exceeds a threshold limit, altering at least one bit within a Layer 2 (L2) header of the message. This bit alteration is subsequently used to determine when to notify a source of the message that the message experienced traffic congestion.

摘要： An adaptive rate control scheduler multiplexes virtual circuit data stream elements for transmission onto a network from a network node. The rate control scheduler is an adaptive circuit that utilizes a schedule table (having multiple time windows) and a set of virtual circuit (VC) specific rate control parameters to supply a transmit controller with a stream of tokens (each of which represents an active VC). The order in which tokens are supplied to the transmit controller is based upon their respective time slot locations in the schedule table. Each time a token is processed by the transmit scheduler, a target time for the next processing of the VC represented by the token is calculated, based upon the stored VC-specific parameters. The token is then inserted into the schedule table in the nearest available time slot to the calculated target time. Included in the calculation of the next target time for a particular token is a gain function based upon an accumulated error value for the associated VC. The accumulated error represents error introduced into the VC's data stream by the scheduling process.

摘要： A node uses a two dimensional array of transmit queues to store frames to be transmitted from the node to another node. The size of the array is governed by the number of directions to which the other node may forward frames once received from the node, and the number of priorities that may be associated with the frames. The transmit queues are distinguished from each other based on direction and priority. A transmitter transmits frames dequeued from the transmit queues to the other node. Control logic that controls the transmit queues receives an indication from the other node whether the other node is experiencing traffic congestion in any of the directions and the priority of frames at or below which the control logic is to control the dequeuing of frames from transmit queues corresponding to the directions in which the other node is experiencing traffic congestion.

摘要： A data transfer system with improved data transfer efficiency is provided. The system consists of a data interchange bus having two data transfer signal paths, an address signal path, and a plurality of control signal paths. Data interchange adapters and memory interchange adapters are coupled to the bus for transferring data thereover. A data interchange adapter transfers data on the first data signal path to another data interchange adapter or to a memory interchange adapter for storage in a memory device. A memory interchange adapter transfers data obtained from a memory device on the second data signal path to a data interchange adapter. Data transfers on the two data signal paths may be made simultaneously. Data transfers on both data signal paths are made synchronously. When an interchange adapter has data to be transferred, it provides an access request signal to a data interchange bus controller which intermittently latches all outstanding access requests, examines them, and produces a sequence of grant signals, each satisfying one of the latched request signals. When the sequence is completed, the controller again latches the access requests which had been raised during the prior latching and granting procedure. The data interchange adapter is further provided with the capability of coupling to two other data buses while coupled to the data interchange bus and includes interface and control circuitry for routing signals between any two of the three buses.
