<p><P>PROBLEM TO BE SOLVED: To provide a communication system which can surely synchronize a state between server systems even if communication between a standby system and an active system is failed. <P>SOLUTION: The communication system is constituted of two server systems 1a and 1b and a plurality of terminals 2a to 2c, and one of the server systems operates as the active system while the other operates as the standby system. In the communication system, communication from the terminals 2a to 2c to the active server system 1a is carried out through the standby server system 1b, and communication contents to the active server system 1a are temporarily held in the standby system 1b to synchronize the respective states of the active server system 1a and standby system 1b by processing the temporarily held communication contents after confirming the completion of the processing of the communication contents in the active server system 1a. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
