Abstract
A data transfer technique in which lossy connections or temporarily interrupted network links neither prevent data transfer nor substantially impair the ease with which a user can transfer data. A sender is advised of receivers on a network that are available to receive data over the network. Also, while data transfer from a sender to a receiver is being performed, the availability of the receiver is monitored. If, during the data transfer, the receiver becomes unavailable to receive the data, then the data transmission stops and the sender is informed that the receiver has become unavailable. The sender continues to monitor the network to determine if the receiver has regained its availability. If the receiver regains availability, the sender is able to automatically resume the data transmission, provided the availability is regained before the network connection is completely lost. The invention is useful for wireless networks as well as wired networks.
