Abstract
A packet data transmission network system is disclosed which comprises a receiver (1), a sender (2) for transmitting data packets to the receiver (1) through a packet data connection via a network element (3). The receiver (1) acknowledges each received data packet by an acknowledgment message which contains header data comprising a window size, the number of transmitted bytes for which the sender (2) has not received an acknowledgment from the receiver (1) being not allowed to exceed the window size. The network element (3) buffers data packets transmitted by the sender (2) and examines and modifies the header data. According to the invention, the network element (3) detects transmission conditions and modifies the window size accordingly.
