Abstract: A transmitting apparatus includes a memory, and a processor coupled to the memory and configured to receive a first packet including first data transmitted from a transmitting node via a first route; receive a second packet including the first data transmitted from the transmitting node via a second route different from the first route, identify, based on first time information regarding the first packet, a first state of the first route, and identify, based on second time information regarding the second packet, a second state of the second route, respectively, and when the first state is not in a first state range, execute a first failure monitoring process on the first route, and when the second state is not in a second state range, execute a second failure monitoring process on the second route, respectively.

Abstract: An information processing device includes a buffer that stores data blocks of a plurality of flows and from which the data blocks are sequentially read; a processor coupled to the buffer and configured to: monitor an input rate that is a sum of data amounts of the plurality of flows input to the buffer per unit of time, and suppress flowing of a data block into the buffer for one or more of the plurality of flows based on a result of monitoring the input rate.

Abstract: In encoding an interlace picture in a field picture, a motion-vector detecting apparatus changes over a reference picture of a P-picture in a field unit, and changes over a reference picture of a B-picture in a frame unit. Moreover, in detecting the motion vector in different predictive directions, the motion-vector detecting apparatus simultaneously carries out a process of the same reference picture by changing over original picture frames.

Abstract: A transmission system can perform flow control even if a flow control instruction is invalidated, and even when the transmission system malfunctions, it can autonomously recover to normal operation for communications. A flow control instruction sender has at least one of two functions including a normal transmission mode to send a flow control instruction for flow control over a congestion state if an event, such as the occurrence of a congestion or the removal of a congestion, occurs when a data receiver receives data, and an autonomous transmission mode to select one of a plurality of congestion states at present in each period and autonomously send a flow control instruction corresponding to the selected congestion state. The flow control instruction sender preferentially sends a flow control instruction in the normal transmission mode in which a congestion actually occurs or is actually removed, when timings of the normal transmission mode and the autonomous transmission mode coincide with each other.

Abstract: An address fault monitoring device and an ATM switching device capable of efficiently monitoring faults and quickly performing counter-fault process. Data storing unit stores data transmitted thereto. Write control unit controls the writing of data with respect to the data storing unit and notifies a read control side of write address information WD including information on a write address. Read control unit controls the reading of data with respect to the data storing unit and notifies the write control unit of read address information RD including information on a read address. Floating address measuring unit counts the number of floating addresses, and when a transmission error has occurred during transmission of the write address information WD or the read address information RD, it reckons the corresponding write or read address as a floating address.
