Claims9
A receiving apparatus receiving data separated into a plurality of fragments, comprising:
- a memory storing code of a computer program, and a processor that executes the code stored in the memory so as to execute the steps of:
- storing a bit table that is used for managing an arrival status of the plurality of fragments;
- detecting a fragment size of said fragments;
- and
- managing the arrival status of the plurality of received fragments with use of the bit table, wherein each one bit of said bit table represents the arrival status of each of the plurality of received fragments whose size is detected by the detecting step.
A receiving method executed by a receiving apparatus receiving data separated into a plurality of fragments, comprising the steps of:
- storing a bit table that is used for managing an arrival status of the plurality of fragments;
- detecting a fragment size of said fragments;
- and
- managing the arrival status of the plurality of received fragments with use of the bit table, wherein each one bit of said bit table represents the arrival status of each of the plurality of received fragments whose size is detected in the detecting step.
A communication method, executed between a transmission apparatus and a receiving apparatus, for communicating data separated into a plurality of fragments, comprising the steps of:
- at the transmission apparatus, transmitting a plurality of fragments;
- and
- at the receiving apparatus, storing a bit table that is used for managing an arrival status of the plurality of fragments, detecting a fragment size of said fragments, and managing the arrival status of the plurality of received fragments with use of the bit table, wherein each one bit of said bit table represents the arrival status of each of the plurality of received fragments whose size is detected in the detecting step.
A transmission apparatus for transmitting data that is separated into a plurality of fragments to a receiving apparatus, comprising:
- a memory storing code of a computer program, and a processor that executes the code stored in the memory so as to execute the steps of:
- fragmenting transmission data into a plurality of fragments with a predetermined size;
- and
- sending a notification to the receiving apparatus such that each one bit of a bit table, which is stored in the receiving apparatus and is used for managing an arrival status of the plurality of fragments, represents the arrival status of each of the plurality of received fragments of said predetermined size.
A transmission method, executed by a transmission apparatus, for transmitting data that is separated into a plurality of fragments to a receiving apparatus, comprising the steps of:
- fragmenting transmission data into a plurality of fragments with a predetermined size;
- and
- sending a notification to the receiving apparatus such that each one bit of a bit table, which is stored in the receiving apparatus and is used for managing an arrival status of the plurality of fragments, represents the arrival status of each of the plurality of received fragments of said predetermined size.
