First Claim
1. A transmission management apparatus, comprising:
- a receiving circuit that receives, from a first transmission terminal connected to a network, a communication request for a communication with a second transmission terminal;
a processor thatselects, a relay device to relay data transmitted from the first transmission terminal and the second transmission terminal among a plurality of relay devices associated with the first transmission terminal or the second transmission terminal based on first relay device identification information or second relay device identification information associated with terminal identification information of the first transmission terminal or the second transmission terminal included in the communication request, and based on information indicating priority of the relay devices to be used by the first transmission terminal, or the second transmission, terminal, anddetermines whether it is necessary to encrypt data to be relayed by the relay device selected by the processor based on the first relay device identification, information or the second relay device identification information, and based on an encryption flag, which is information indicating whether it is necessary to encrypt data to be relayed by the relay device identified by the first relay device identification information or the second relay device identification information; and
a transmitting circuit that transmits a determination result obtained by the processor to the first transmission terminal and, the second transmission terminal,whereinthe first transmission terminal and the second transmission terminal transmit the data to the selected relay device based on the determination result.

Abstract
A transmission management apparatus includes a receiving unit that receives, from a first transmission terminal, a communication request for a communication with a second transmission terminal; a fists storage unit that stores therein terminal identification information for identifying the transmission terminals and relay device identification information for identifying a relay device that relays data to be transmitted and received by the first transmission terminal, in an associated manner; a relay device selecting unit that selects the relay device associated with the terminal identification information of the first transmission terminal in the first storage unit; a second storage unit that stores therein the relay device identification information and encryption necessity information in an associated manner; and an encryption necessity determining unit that determines whether encryption is needed based on the encryption necessity information associated, in the second storage unit, with the relay device selected by the relay device selecting unit.
