A communication apparatus includes a connection port and a processor. The connection port is connected to a switch apparatus. The processor is configured to acquire data to be transmitted to an external apparatus. The processor is configured to generate a packet destined to the external apparatus. The packet contains the data. The processor is configured to store the packet in a buffer. The processor is configured to acquire the packet from the buffer. The processor is configured to transmit the packet to the switch apparatus via the connection port. The processor is configured to acquire a state of a network to which the connection port is connected. The processor is configured to control, on basis of the state of the network and a predetermined packet generation time, a number of packets to be generated.

Communication apparatus, information processing apparatus, and method of controlling communication apparatus

An information processing device includes a transfer unit and an interface unit, the interface unit distributes transmission to a plurality of first lanes, and generate reception information from a plurality of pieces of distribution reception data received through a plurality of second lanes, the transfer unit includes a reception processing unit to extract reception data included in the reception information, and first error information indicating an error in any of the first lanes and a degeneration management unit to generate first degeneration information indicating a use stop lane among the first lanes, based on the first error information, generate second degeneration information indicating a use stop lane among the plurality of second lanes, based on second error information that is output from the interface unit, and cause the transmission processing unit to generate transmission information including the second degeneration information.

Information processing device, information processing system, and communication device

In a network of a variable length packet system, a bps calculator colors an inputted packet based on a peak bandwidth or a committed bandwidth of a data bit number per unit time for every flow and a packet length of the inputted packet, a pps calculator colors the inputted packet based on a peak bandwidth or a committed bandwidth of a packet number per unit time for every flow and a packet number of the inputted packet, and one of a color of packet to be discarded, a color of packet to be passed and a color of packet to be discarded with a probability, within the colors obtained by colorings at both calculators is determined by a color selector.
