ABSTRACT:
A system is provided for the safe transfer of large data files over an unreliable network link in which the connection can be interrupted for a long period of time. In the subject system, the sender sends a file with a unique signature which is recognized by the receiver, with the signature providing information as to file size. Upon the occasion of an interrupted communication over the link, the receive side waits for another connection. Upon the establishment of the connection, the receive side recognizes the signature of the file as the file which was being transmitted at the time of the interruption and requests blocks of data from the sender from the point at which the interruption occurred, with the point being established by the file size and the time of the interruption. The result is a restartable transfer of the transmission of information from the sender to receiver from the place where it left off, thus eliminating the annoyance of having to restart the transmission from the beginning.
