<p><P>PROBLEM TO BE SOLVED: To attain communication using a DNS cache even by inter-private network communication through a global network. <P>SOLUTION: An address converting device A104 having a private network 101 as subordinate receives a DNS query to make a query for the address of a server terminal 110 from a client terminal 107, and assigns a transmission origin port number group to be used for TCP communication with the server terminal 110, and notifies the address converting device B105 for sharing it. As a result, once address solution by DNA processing is performed, it is possible for the client terminal 107 to perform communication between a plurality of TCP sessions without transmitting any DNS query. Therefore, it is possible for the client terminal to use a plurality of DNS caches. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
