  • (a) transmitting a connection request from a source terminal to a destination terminal in the data communication network, the connection request seeking to establish a connection between the source and destination terminals;

    (b) determining at the destination terminal a source identifier field length for recording a source identifier in data packets to be transmitted in the connection, wherein the source identifier identifies the connection;

    (c) determining at the destination terminal a sequence number field length for recording a sequence number in data packets to be transmitted in the connection, wherein the sequence number identifies the relative position of a data packet in a series of data packets transmitted in the connection;

    (d) transmitting a connection reply from the destination terminal to the source terminal that indicates the determined source identifier field length and sequence number field length; and

    (e) transmitting one or more data packets from the source terminal to the destination terminal, the one or more data packets including;

    (i) a source identifier recorded in a source identifier field sized according to the determined source identifier field length; and

    (ii) a sequence number recorded in a sequence number field sized according to the determined sequence number field length.
