摘要： An input line interface device that is used to accommodate packets from a high-speed line efficiently and to reduce a processing load on a back stage caused by routing control. A packet allotting section divides a variable-length packet, allots divided packets to parallel lines, and outputs the packets. A flow group classifying section classifies the packets into flow groups on each of the parallel lines. A sequence number giving section gives the packets sequence numbers corresponding to or independent of the flow groups. A buffering section stores the packets to which the sequence numbers have been given in a buffer or reads out them from the buffer to exercise sequence control over the packets in the flow groups. A flow separating switch separates the packets according to the flow groups and outputs the packets.

摘要： A scheduling system is capable of causing no deterioration of characteristics even under equal and unequal loads, eliminating the necessity for high-speed repetitive scheduling and complicated arithmetic processes, simplifying its architecture and having its processing speed which does not depend upon a device capability. For attaining this system, an inter-highway pointer is updated to an adjacent line (rightward) when the scheduling for all the lines are finished. If the inter-highway pointer is updated N-times in the same direction (clockwise), the same pointer is updated to an adjacent line in a reverse direction (counterclockwise) in next N-processes of scheduling.

摘要： To achieve QoS control, drop control and multicast control of a variable-length packet at high speed in small scale hardware, a packet divider divides a variable-length packet into fixed-length packets, and an input buffer section stores the divided fixed-length packets into queues by output lines and by QoS classes. A large number of QoS classes are mapped into only two kinds of classes including a guaranteed bandwidth class for which an assigned bandwidth is guaranteed and a best effort class for which a surplus bandwidth is allocated, thereby to achieve scheduling at the input side by an inter-line scheduler. An output buffer section assembles a variable-length packet from fixed-length packets that have been obtained by switching at a switch section in an output buffer section. A QoS control is performed based on a packet length.

摘要： A storage unit includes an alarm state/timer table, an alarm state table, an alarm state OR-representation table, an alarm state change OR-representation table, an alarm state latch circuit, and a statistical information memory. A collection unit extracts the identifier and data from a cell that passes through a switching unit. An update unit updates associated data in the storage unit. A readout unit reads the updated data and sends it to a call processing processor. An address generation section selectively generates the address for data needing to be updated. An adjustment section forces the readout unit to wait until a cell slot arrives in which no data is updated.
