Abstract
A method and an apparatus for sharing a file with at least one peer terminal by a terminal in a Peer-to-Peer (P2P) network are provided. The method includes dividing a file allowed to be shared and generating two or more fragment files; generating file division information used for reconstructing the file allowed to be shared by using the fragment files; combining the file division information with each of the fragment files; and transmitting the combined file division information and fragment files to the at least one terminal.
Claims20
A method of sharing a file with at least one peer terminal by a terminal in a Peer-to-Peer (P2P) network, the method comprising:
- dividing a file allowed to be shared and generating two or more fragment files;
- generating file division information used for reconstructing the file allowed to be shared by using the fragment files;
- combining the file division information with each of the fragment files;
- and
- transmitting the combined file division information and fragment files to the at least one terminal.
A method of sharing a file with at least one peer terminal by a terminal in a Peer-to-Peer (P2P) network, the method comprising:
- receiving, from a peer terminal, at least one fragment file generated by dividing a file allowed to be shared into two or more fragment files;
- and
- when a network is changed, transmitting the received at least one fragment file to one or more peer terminals located on the changed network.
An apparatus in a terminal for sharing a file with at least one peer terminal in a Peer-to-Peer (P2P) network, the apparatus comprising:
- a controller for dividing a file allowed to be shared, generating two or more fragment files, generating file division information used for reconstructing the file allowed to be shared by using the fragment files, and combining the file division information with each of the fragment files;
- and
- a transceiver for transmitting the combined fragment files with the file division information to the at least one peer terminals.
An apparatus in a terminal for sharing a file with at least one peer terminal in a Peer-to-Peer (P2P) network, the apparatus comprising:
- a transceiver for performing transmission/reception;
- and
- a controller for, when a network is changed after receiving at least one fragment file, which is generated by dividing a file allowed to be shared into two or more fragment files, from a peer terminal, transmitting the received at least one fragment file to the at least one peer terminal located on the changed network.
