| 20090254637 | CODING METHOD OF VECTOR NETWORK ADDRESS - A coding method of vector network address (VNA), which encodes the VNA according to output port names (OPN) of one source device and the forwarding devices along the Data Transmission Path (DTP). Each OPN acts as a component address, and all component addresses compose a sequence in the order along the direction of the DTP. This sequence is the result of the coding method, i.e. the VNA. More specifically, the VNA is a finite sequence as follows: The first component address in the sequence is the OPN of the source device, the second that is the OPN of the first forwarding device in the DTP, the third that is the OPN of the second forwarding device in the DTP, and so on. The final OPN in the sequence is the OPN of the final forwarding device in the DTP. | 10-08-2009 |
| 20080291885 | METHOD FOR COMMUNICATION OF MIPv6 MOBILE NODES - A method for communication of MIPv6 mobile nodes, comprising: the mobile node accesses network at access location and obtains care of address, calculating a privacy identifier PID using the care of address etc. the mobile node replaces its home address by the PID, and sends the PID and the care of address together as binding update message to the home agent and correspondent node, the home agent and correspondent node recover the home address for the mobile node using the PID after they have received the binding update message. The method for communication of MIPv6 mobile nodes according to the present invention uses that a configuring replaced identifier replacing the home address is sent, thereby hiding Ipv6 address. By setting PID and its algorithm, we improve the sequence number in the binding update messages enabling the sequence number has randomness, and prevent the intercepting person continue tracking the mobile node through the home address. | 11-27-2008 |
