Abstract: An information processing apparatus includes a control section, and can temporarily pause at least some of its own functions. The control section of the information processing apparatus performs control for notifying, when at least some of its own functions are to be temporarily paused, a first apparatus that has a specific function of a function temporary pause period within which at least some of functions of the first apparatus are to be temporarily paused. Further, the control section of the information processing apparatus performs control for directing, when at least some of its own functions are to be temporarily paused, a second apparatus that does not have a specific function to restrain transmission. Power consumption of the information processing apparatus can be reduced.

Abstract: The efficiency of wireless communication is improved.
A communication system includes a first information processing apparatus and a second information processing apparatus. The first information processing apparatus controls to determine an information amount to be used for a receipt acknowledgment response to packets to be transmitted to a second information processing apparatus on the basis of information relating to the packets and notifies the second information processing apparatus of that determined information amount. The second information processing apparatus controls to return the receipt acknowledgment response to the packets transmitted from the first information processing apparatus to the first information processing apparatus on the basis of the information amount notified from the first information processing apparatus.

Abstract: An information processing device includes a control unit. The control unit performs control to restrict retransmission of data or transmission of a request for an acknowledgment of receipt of the retransmission data, in accordance with the congestion status of a wireless transmission traffic. The control unit also performs control to transfer acquired data to an upper layer in case of having successfully acquired the data up to a predetermined sequence number in multicast data transmitted from another device that restricts retransmission of data in accordance with the congestion status of a wireless transmission traffic. The device can prevent decreases in the total throughput in a network.

Abstract: Data communication is performed appropriately.An information processing apparatus includes a control unit. In a case of transmitting data by using wireless communication, the control unit performs control of performing transmission while including determination information with which a device in a transmission destination of the data determines in a data link layer whether to pass the data to a higher layer of the data link layer into the data. Also, in a case of receiving data by using wireless communication, the control unit performs control of determining whether to pass the data to a higher layer of a data link layer on the basis of information included in the data (determination information that can be grasped in data link layer).
