Abstract: A file is transferred between client and server. The client determines file transfer resources and good time slots available at the client, and communicates a file transfer plan to upload the file to the server; the file transfer plan specifies the file resources available at the client and time slots. The server acknowledges the file transfer plan, possibly with adjustments to the available time slots, and the server communicates a postbox indicating the location where the file is to be uploaded. The client executes a file transfer process specified in the file transfer plan, based on the file transfer resources available at the server and client, to upload the file to a respective location specified by the postbox. There may be plural uploads of parts of the file, at different available time slots, and/or different combinations of file transfer resources specified in the acknowledged file transfer plan.

Abstract: Certain example embodiments relate to data transfer techniques. A server receives from a client, using a standard communication protocol, a file operation command that relates to a data transfer and indicates data to be transferred and/or a preference for how to transfer data. If the server and client do not have implemented thereon complementary plugins configured to facilitate the data transfer in accordance with the file operation command, the data transfer takes place between the server and client using the standard communication protocol. If the server and client have implemented thereon complementary plugins configured to facilitate the data transfer in accordance with the file operation command, the data transfer takes place using (a) a common communication protocol that is implemented by the complementary plugins but different from the standard communication protocol, and/or (b) data selected and/or transformed by the server-side plugin and understandable by the client-side plugin.
