<p><P>PROBLEM TO BE SOLVED: To provide a system that can improve the quality and reliability of TCP/IP communications as the communications are multiplexed. <P>SOLUTION: A server 1 and a client 2 respectively have link establishing sections 1111 and 2111 which check whether or not links and pluralities of spare links to be established in user processing sections 112 and 212 are established upon receiving usage confirmation requests for TCP ports from the processing sections 112 and 212, and link state monitoring sections 1113 and 2113 which perform a health check by transmitting a test message to all destination TCP ports to be established at preset intervals. The server 1 and the client 2 also respectively have state-of-link management sections 1112 and 2112 which manage establishment checking results the health checking results and, upon detecting faults, extract unused high-priority spare links from the pluralities of spare links and inform the user processing sections 112 and 212 of the extracted spare links. <P>COPYRIGHT: (C)2003,JPO</p> |
