The present disclosure relates to a method and device for transferring TCP data packets from a plurality of server nodes to a client node, wherein the proxy node captures all TCP data packets of the TCP flows, buffers the captured TCP data packets in a TCP stack and updates an active TCP flow list in a subscriberrecord representing the client node. The method comprises estimating (S20) a current proxy scheduling capacity from a current maximum amount of data allowed concurrently in transmission in oneor more TCP flows to the client node. When a TCP data packet transmission triggering event is received (S21), a TCP data packet retrieved from the TCP stack is scheduled (S22) in accordance with the estimated current proxy scheduling capacity and order given bythe active flow list. The scheduled TCP data packet is transmitted (S23) and the active flow list is updated (S24), whereupon the step of scheduling (S22) a TCP flow for transmission is repeated until the current proxy scheduling capacity has been reached or there are no TCP flows in the active flow list (S25). |
