Method and system for data transmission over a network link between computers with the ability to withstand temporary interruptions

A method for transmitting data from a first computing device to a second computing device via a network, said method comprising:

• (a) searching the network for computing devices available to receive data over the network;
• (b) displaying an indicator for each of the computing devices available to receive data on a display screen of the first computing device;
• (c) establishing a connection via the network from the first computing device to the second computing device;
• (d) sending data from the first computing device to the second computing device over the network while monitoring the availability of the second computing device to receive the data over the network;
• (e) stopping said sending (d) of the data when the second computing device becomes unavailable;
• (f) determining whether the second computing device regains availability before the connection is lost;
• and
• (g) resuming said sending (d) of the data after a temporary interruption when said determining (f) determines that the availability of the second computing device is regained before the connection is lost.

A method for transmitting data from a first computing device to a second computing device via a network, said method comprising:

• (a) searching the network for computing devices available to receive data over the network;
• (b) determining if the second computing device is one of the computing devices available to receive data over the network;
• (c) establishing a connection via the network from the first computing device to the second computing device when the second computing device is available and when there is data to be transmitted from the first computing device to the second computing device;
• (d) sending data from the first computing device to the second computing device over the network;
• (e) monitoring the availability of the second computing device to receive the data over the network;
• (f) suspending said sending (d) of the data to the second computing device if the second computing device loses availability;
• (g) maintaining the connection from the first computing device to the second computing device via the network during said suspending (f);
• (h) resuming said sending (d) of the data to the second computing device if the second computing device regains availability;
• and
• (i) terminating the connection from the first computing device to the second computing device if the second computing device does not regain availability.

A system for transmitting data from a first computing device to a second computing device, said system comprising:

• a network capable of interconnecting the first computing device to a plurality of other computing devices including the second computing device;
• search means for searching the network to determining which of other devices on the network are available to receive data from the first computing device;
• a display screen, said display screen displaying at least an indicator for each of the available devices on the network;
• data transfer means for transferring of data from the first computing device to the second computing device via a network link, provided one of the indicators on said display screen corresponds to the second computing device, with the network link supporting a connection between the first computing device and the second computing device;
• a message window for displaying a message on said display screen of the first computing device when the second computing device becomes unavailable to receive the data after the transfer of data has began but before the transfer of data is complete;
• and
• data transfer resumption means for resuming the transfer of data if the second computing device again becomes available,
• wherein when the second computing device becomes unavailable during the transfer of the data to the second computing device, the transfer of the data stops but the connection from the first computing device to the second computing device via the network link temporarily remains open so that the transfer of the data can resume if the second computing device again becomes available before the connection is lost.

A computer readable medium containing program instructions for transmitting data over a network link, said computer readable medium comprising:

• computer readable code devices for searching the network for computing devices available to receive data over the network;
• computer readable code devices for displaying an indicator for each of the computing devices available to receive data on a display screen of a first computing device;
• computer readable code devices for establishing a connection via the network from the first computing device to a second computing device;
• and
• computer readable code devices for sending data from the first computing device to the second computing device over the network while monitoring the availability of the second computing device to receive the data over the networks;
• computer readable code devices for stopping the sending of the data when the second computing device becomes unavailable;
• computer readable code devices for determining whether the second computing device regains availability before the connection is lost;
• and
• computer readable code devices for resuming the sending of the data after a temporary interruption when the determining operates to determine that the availability of the second computing device is regained before the connection is lost.

A user interface for a computer system, the user interface being visually displayed on a display screen of the computer system, the computer system being connected to a network of other devices, said user interface comprising:

• search means for searching the network to determine the devices on the network available to receive data from the computer system;
• display means for displaying on the display screen a window having an indicator for each of the available devices on the network;
• means for periodically updating said window so that the indicators displayed provide an accurate account of the available devices;
• means for invoking a transfer of data from the computer system to a selected one of the available devices;
• a message window for displaying a message on the display screen of the computer system when the selected one of the available devices to which data is being sent becomes unavailable to receive the data before the transmission of the data is complete, the message indicating the stoppage of the transfer of the data when the selected one of the available devices becomes unavailable and that resumption of the transfer of data can be had if the availability of the selected one of the available devices returns within a predetermined period of time.
