In a method of data transmission in a data communication network, data packets may be tormatted according to different transmission protocols ('secondary data packets') that are received for transmission through the data communication network and may be packed into one or more 'primary data packets' formatted according to the transmission protocol of the data communication network. In addition to a sequence number, the primary data packets may include a first packet offset to identify the location of a first new secondary data packet that is packed into the primary data packet. A first packet offset field length may be determined during connection negotiation. The data transmission method of the invention may include packing one or more secondary data packets, or a portion thereof, in a primary data packet to fill the primary data packet, thus minimizing unused data bits in the primary data packet.

Method of data transmission in a data communication network

A method for transmitting data over a network is disclosed along with destination and source terminals in a data communication network. The method comprises receiving a connection request at a destination terminal; determining, at the destination terminal, a field length for the recording of an element in a data packet to be transmitted to the destination terminal; and sending a connection reply indicating the field length. The destination terminal comprises a processor for determining a field length upon receipt of a connection request from a source terminal, where the field length is used by the source terminal for recording a element in a data packet to be transmitted to the destination terminal. The source terminal comprises a processor for recording an element in a field of a data packet having a field length determined by a destination terminal. The elements in a field of a data packet include, without limitation, a sequence number in a sequence number field, a source identifier in a source identifier field, and a first packet offset in a first packet offset field.

A method of data transmission in a data communication network includes negotiating a connection between a source terminal and a destination terminal in the data communication network. During the connection negotiation process, optimal field lengths are determined for recording a source identifier and a sequence number in data packets transmitted in the connection. The source identifier identifies a connection from the source end to the destination end of the data transmission, while the sequence number identifies the relative position of a data packet in a series of data packets transmitted in the connection. The length of the source identifier and sequence number fields may either be calculated or selected from a set of predetermined field length values. Data packets formatted according to different transmission protocols ('secondary data packets') that are received for transmission through the data communication network are packed into one or more 'primary data packets' formatted according to the transmission protocol of the data communication network. In addition to a source identifier and sequence number, the primary data packets include a first packet offset to identify the location of a first new secondary data packet that is packed into the primary data packet. A first packet offset field length is determined during connection negotiation. The data transmission method of the invention includes packing one or more secondary data packets, or a portion thereof, in a primary data packet to fill the primary data packet, thus minimizing unused data bits in the primary data packet. After transmission, the primary data packets are reordered, if necessary, and the secondary data packets are unpacked therefrom.
