Abstract
An information processing apparatus including a control unit that performs control for adding, to request information for requesting a different apparatus for a confirmation response to a plurality of data transmitted to the different apparatus, notification information. The notification information is information regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data. Further, the control unit transmits the request information, to which the notification information is added, to the different apparatus.
Claims20
An information processing apparatus, comprising:
- circuitry configured to perform control for
- adding a notification information field to a request information field for requesting each of a plurality of different apparatuses for a confirmation response to specific data from among a plurality of data transmitted to the plurality of different apparatuses, the request information field regarding a start sequence number for the confirmation response, the notification information field regarding sequence numbers described in a bitmap of a variable length corresponding to the specific data from among the plurality of data for the confirmation response, the variable length being based on a set value of a compressed bitmap, and
- transmitting the notification information field together with the request information field, to which the notification information field is added, and an indication that the notification information is added, to each of the plurality of different apparatuses.
An information processing apparatus, comprising:
- circuitry configured to:
- receive specific data from among a plurality of data transmitted from a different apparatus to a plurality of information processing apparatuses including the information processing apparatus;
- receive a request information field, a notification information field, and an indication that the notification information is added from the different apparatus,
- the request information field regarding a start sequence number for a confirmation response to the specific data from among the plurality of data, the notification information field regarding sequence numbers described in a bitmap of a variable length corresponding to the specific data from among the plurality of data, the variable length being based on a set value of a compressed bitmap;
- and
- decide, based on the notification information field, whether or not undelivered data exists from among the specific data from among the plurality of data.
