Abstract:
1. A method for communication between a first communication terminal and a second communication terminal, the method comprising: compressing a header of a first packet associated with data being sent to the second communication terminal by the first communication terminal, and attaching information to be used to recognize whether or not header extension processing is required and to recognize a forwarding route to the second communication terminal to a compressed first packet whose header is compressed; generating a second packet storing the compressed first packet by the first communication terminal, and sending the second packet to a network; upon receiving the second packet from the first communication terminal by a data forwarding unit that is one of the units constituting the network, extracting the compressed first packet from the second packet by terminating the second packet, and recognizing whether or not the compressed first packet requires the header extension processing and the forwarding route on the basis of the information attached to the compressed first packet; and sending, if the compressed first packet does not require the header extension process, the compressed first packet to the recognized forwarding route without extending the header of the first packet.
