Patent ID: 8885008

Claim:
A transmission management system that selects relay devices, which relay at least one of image data and voice data to be communicated between a plurality of transmission terminals via a communication network, the system comprising: a relay device management unit that manages relay device-specifying information representing an IP address used to specify each of the relay devices on the communication network or a Fully Qualified Domain Name (FQDN) corresponding to the IP address, for every piece of relay device identification information identifying each of the relay devices; a terminal management unit that manages terminal-specifying information representing an IP address used to specify each of the transmission terminals on the communication network or a FQDN corresponding to the IP address, for every piece of terminal identification information identifying each of the transmission terminals; an identification information receiving unit that receives, from a first transmission terminal as a predetermined request source, first terminal identification information for identifying the first transmission terminal as the request source and second terminal identification information for identifying a second transmission terminal as a destination; an extracting unit that extracts the terminal-specifying information of a corresponding transmission terminal of the transmission terminals by searching the terminal management unit based on at least one of the first terminal identification information and the second terminal identification information; and a primary selecting unit that searches the relay device management unit based on an IP address represented by the extracted terminal-specifying information or an IP address corresponding to a FQDN represented by the extracted terminal-specifying information to select two or more pieces of relay device identification information of two or more of the relay devices, to which relay device-specifying information representing two or more IP addresses closest to the IP address represented by the extracted terminal-specifying information or the IP address corresponding to the FQDN represented by the extracted terminal-specifying information or representing FQDNs corresponding to the two or more IP addresses, is allocated.
