Abstract
A system, method, node and computer program for transfer of downlink data packets from a server () to a client () across at least one first data packet transport domain () and at least one second data packet transport domain () is disclosed. The two data packet transport domains () have different transport characteristics and are interconnected via at least one proxy (). The server () is located in front of the first data packet transport domain () and the client () is located behind the second data packet transport domain (). The method comprises sending, by the server (), a data packet to the client () and sending, by the proxy (), responsive to the reception of the data packet, an acknowledgement to the server () acknowledging the reception of the data packet or a failure to receive the data packet at the proxy (). The method further comprises forwarding, by the proxy (), the received data packet to the client () and deleting, by the proxy (), after sending of the acknowledgement to the server () and forwarding the received data packet to the client (), the received data packet in the proxy () and determining, by the server (), a delivery status of the data packet or a failure location in either of the two data packet transport domains () based on acknowledgements received from the client () and/or the proxy ().
