<P>PROBLEM TO BE SOLVED: To provide a communication system, a relay device, and a relay program for easily securing safety of communication between devices without requiring a dedicated device for unitary managing a connection condition. <P>SOLUTION: A remote conference system 1 includes a first and a second conference management devices 2A, 2B in which a connection request is allowed to communicate data to each other when the connection request satisfies a connection condition, a first to a third terminal devices 3A to 3C, and the like. Each of the first to third terminal devices 3A to 3C includes: a connection request part 300 which operates as a relay device and makes a connection request for satisfying the connection condition of both the first and second conference management devices 2A and 2B; and a data relay part 301A for relaying data transmitted and received between the first and second conference management devices 2A and 2B when the connection request by a requesting means is allowed by both the first and the second conference management devices 2A, 2B. <P>COPYRIGHT: (C)2010,JPO&INPIT |
