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.

First claim

The invention claimed is:

1. An information processing apparatus, comprising:
a controller configured to perform 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 regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data and transmitting the request information, to which the notification information is added, to the different apparatus,
wherein the controller adds and transmits the notification information regarding a sequence number corresponding to specific data from among the plurality of data to and together with the request information to the different apparatus, and
wherein the specific data is data to be passed to an upper layer.

2. The information processing apparatus according to claim 1 , wherein the specific data is data destined for the information processing apparatus.

3. The information processing apparatus according to claim 1 , wherein the specific data is data of multicast communication to be received.

4. The information processing apparatus according to claim 1 , wherein the specific data is data from which parity information is removed.

5. The information processing apparatus according to claim 1 , wherein the request information is a block acknowledgement request frame.

6. The information processing apparatus according to claim 1 , wherein the controller adds and transmits the notification information regarding successive sequence numbers or intermittent sequence numbers from among the sequence numbers corresponding to the plurality of data to and together with the request information to the different apparatus.

7. An information processing apparatus, comprising:
a controller configured to decide, when request information that requests a confirmation response to a plurality of data transmitted from a different apparatus and to which notification information regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data is added is received from the different apparatus, based on the notification information whether or not undelivered data exists from among data to be received by the information processing apparatus from among the plurality of data and perform, when the undelivered data does not exist, control for passing the plurality of data to an upper layer.

8. The information processing apparatus according to claim 7 , wherein the controller transmits, when the undelivered data exists, the confirmation response to which information regarding a sequence number for specifying the undelivered data is added to the different apparatus and performs, when the undelivered data no more exists as a result of re-sending of the undelivered data from the different apparatus, control for passing the plurality of data to the upper layer.

9. The information processing apparatus according to claim 7 , wherein the controller passes, when the plurality of data that have successive sequence numbers are received without an error, the plurality of data to the upper layer without receiving the request information.

10. The information processing apparatus according to claim 7 , wherein the controller considers, when the plurality of data include data of parity information, the undelivered data that is repaired based on the parity information as data received already.

11. A communication system, comprising:
a first information processor configured to add, to request information for requesting a second information processor for a confirmation response to a plurality of data transmitted to the second information processor, notification information regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data and transmit the request information, to which the notification information is added, to the second information processor; and
the second information processor configured to decide, when the request information is received from the first information processor, based on the notification information included in the request information whether or not undelivered data exists from among data to be received by the first information processor from among the plurality of data and pass, when die undelivered data does not exist, the plurality of data to an upper layer.

12. A method, comprising:
performing, by an information processing apparatus, 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 regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data and transmitting the request information, to which the notification information is added, to the different apparatus; and
adding and transmitting the notification information regarding a sequence number corresponding to specific data from among the plurality of data to and together with the request information to the different apparatus, and
wherein the specific data is data to be passed to an upper layer.

13. A method, comprising:
deciding, by an information processing apparatus, when request information that requests a confirmation response to a plurality of data transmitted from a different apparatus and to which notification information regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data is added is received from the different apparatus, based on the notification information whether or not undelivered data exists from among data to be received by the information processing apparatus from among the plurality of data and perform, when the undelivered data does not exist, control for passing the plurality of data. to an upper layer.
