Abstract:
1. A gateway module for connecting at least a first and second network, comprising: a connection set up module configured to set up a transport layer connection between two correspondent nodes in the first and second networks in divided forms of first and second connections, a control module configured to control the connection set up module by making a determination to carry out or not carry out a connection set up by the connection set up module according to an information content of a packet that contains a transport layer protocol data unit from the correspondent node in the second network requesting a set up of the transport layer connection between the first and second networks; a data processing module configured to determine if data received from the correspondent node in the first network is new, and if the data received is new, buffer and forward the data to the correspondent node in the second network; and an acknowledgement processing module configured to acknowledge the data received from the correspondent node in the first network and process acknowledgements received from the correspondent node in the second network, wherein the processing comprises retransmitting buffered data, by the data processing module, if the correspondent node in the second network does not acknowledge forwarded data within a timeout period.
