摘要： A data processing device connected to another data processing device through an asynchronous network to receive/transmit data from/to the other data processing device. The data processing device monitors an accumulation amount of a reception buffer for receiving data transmitted from the other data processing device, controls a self reception data processing clock based upon the monitored accumulation amount, transmits to the other data processing device transmission clock control information controlling a transmission clock in the other data processing device based upon the monitored accumulation amount, and controlling a self transmission clock based upon the clock control information transmitted from the other data processing device.

摘要： A packet transmission device improved in packet transmission efficiency. Each packet input processor generates a pointer and identifies a packet type with respect to a received packet, and generates identification data including the pointer and the packet type identification result. A memory access controller detects a header readout amount of the packet based on the packet type identification result, generates first readout data including the header readout amount and a readout pointer indicative of a storage location of the packet in a shared memory, and adaptively reads out header data of the packet from the shared memory in accordance with the first readout data. A protocol processor analyzes the destination of the read header data, and a packet updater updates the old destination address of the packet to a new one to generate a packet with the updated destination address, and outputs the generated packet.

摘要： An output-band control unit extracts delay information indicating a delay state of a packet from a packet received, and controls a setting of an output band of the packet based on the delay information. A packet-transmission control unit updates the delay information based on the output band of which the setting is controlled by the output-band control unit and an internal delay that occurs internally with respect to a packet output in the output band, and transmits the packet with the delay information updated.

摘要： A router includes a plurality of control units connected in parallel, each having an input connected to a receiving interface and an output connected to a transmitting interface, and performing timing control of outgoing packets to the transmitting interface based on header information of incoming packets, the incoming packets being stored in a memory and the stored packets being transmitted to the transmitting interface in order of transmission of the outgoing packets. A distributing unit distributes transmitting sequence information, related to the stored packets in the memory, to other control units. The distributing unit determines whether a packet sequence inversion in the control unit occurs, based on a result of comparison of the transmitting sequence information received and the transmitting sequence information held by the control unit, inhibiting the transmission of the stored packets to the transmitting interface when the packet sequence invention is detected.
