A packet repeater (e.g., gateway) is applicable to an integrated digital network system which incorporates a first network (e.g., Internet) and a second network (e.g., satellite communication system) comprising an upstream line and a downstream line which are asymmetrical with respect to each other in data transmission speed. In the packet repeater, specific data (e.g., TCP data) are extracted from plural packets and are assembled together into a single transmission packet on the basis of the maximal amount of storable data, which is greater than the maximal segment size notified from a receiver under conditions in which the reception window size fulfills the maximal amount of storable data. The packet repeater has reception acknowledgement response agency functions for provisionally sending back a reception acknowledgement response in reply to the prescribed number of packets transmitted via the first network before receiving a reception acknowledgement response from the receiver receiving the transmission packet.
