FILE TRANSFER METHOD AND FILE TRANSFER PROGRAM
PROBLEM TO BE SOLVED: To transfer a file efficiently by TCP.SOLUTION: A file transfer method has a step where a processing section (100) divides a single file (4) in a memory (110) into N (N is an integer of 2 or more) data groups (4-0 through 4-N-1), and creating N transfer jobs indicating the N da...

Zusammenfassung: | PROBLEM TO BE SOLVED: To transfer a file efficiently by TCP.SOLUTION: A file transfer method has a step where a processing section (100) divides a single file (4) in a memory (110) into N (N is an integer of 2 or more) data groups (4-0 through 4-N-1), and creating N transfer jobs indicating the N data groups and an offset position (OF), and a step where the processing section (100) assigns the transfer job to M transfer threads of simultaneous connection number of TCP(Transmission Control Protocol), and transfers the M data groups and an offset position specified by M transfer jobs, out of the N data groups and an offset position specified by N transfer jobs, in parallel, by M connections.SELECTED DRAWING: Figure 2
【課題】ファイル転送をTCPにより効率良く実行する。【解決手段】処理部(100)が、メモリ(110)内の単一のファイル(4)をN個(Nは整数で、2以上)のデータ群(4−0〜4-N−1)に分割し、N個のデータ群とオフセット位置(OF)を示すN個の転送ジョブを作成する工程と、処理部(100)が、TCP(Transmission Control Protocol)の同時接続数のM個の転送スレッドに前記転送ジョブを割り当て、M個のコネクションにより、N個の転送ジョブで指定されたN個のデータ群とオフセット位置の内、M個の転送ジョブで指定されたM個のデータ群とオフセット位置を並列に転送する工程とを有する。【選択図】図2 |
