Abstract
A method of operating a data transfer device is disclosed. The data transfer device is connected to a partner data transfer device via a wide area network, to relay data packets between first and second communication devices. The method further includes: receiving first-protocol-based data packets from the first communication device via a first-protocol-based connection within a first access network; in response to reception of the first-protocol-based data packets, sending back acknowledgement to the first communication device via the first-protocol-based connection, on behalf of the second communication device; encapsulating first-protocol-based data packets received from the first communication device, to convert the first-protocol-based data packets to a plurality of second-protocol-based data packets; and transferring the second-protocol-based data packets to partner data transfer device via a second-protocol-based connection within the wide area network. The first protocol is a sliding window protocol, and the second protocol is a protocol without using a sliding window.
