Mapping notification system for relating static identifier to dynamic address
First Claim
1. A network-based communication system, comprising:
- at least one server containing a processor for connecting a plurality of processing modules including;
a processing module embodied in hardware for obtaining a corresponding dynamic address by sending an identifier to a mapping notification system which stores a pair of an identifier and a dynamic address; and
at least one additional processing module embodied in hardware for determining whether or not a dynamic address stored in the mapping notification system is correct by accessing other communication node to which the dynamic address obtained by the processing module is assigned,wherein when the determining means determines that the address is not correct,(i) said obtaining process and determination process are executed again,(ii) an execution of a process to be executed after said determination process is stopped, or(iii) a control process for preventing from sending back a reply of said address from the mapping notification system is executed.

Abstract
A1 A communication system comprises obtaining a corresponding dynamic address by sending an identifier to a mapping notification system which stores a pair of an identifier and a dynamic address; and determining whether or not a dynamic address stored in the mapping notification system is correct by accessing other communication node to which the dynamic address obtained by the obtaining means is assigned. The system also compares the identifier sent to the mapping notification system and a reply for the access to the communication node. If the system determines that the address is not correct, the obtaining process and determination process are executed again, an execution of a process to be executed after the determination process is stopped, or a control process for preventing from sending back a reply of the address from the mapping notification system is executed.

14. A communication node, comprising:
-
an obtaining means for obtaining a corresponding dynamic address by sending an identifier to a mapping notification system which stores a pair of an identifier and a dynamic address; and a determination means for determining whether or not a dynamic address stored in the mapping notification system is correct by accessing other communication node to which the dynamic address obtained by the obtaining means is assigned, wherein when the determining means determines that the address is not correct, (i) said obtaining process and determination process are executed again, (ii) an execution of a process to be executed after said determination process is stopped, or (iii) a control process for preventing from sending back a reply of said address from the mapping notification system is executed.
