Abstract: A transmission network system includes a network terminating device connected to a user terminal and an authentication information device connected to the network terminating device through a transmission network. The transmission network is connected to a reference clock that holds a reference time. The network terminating device includes a terminating internal clock that synchronizes with the reference clock, when receiving a first frame from the user terminal, generates a second frame including a time outputted from the terminating internal clock as a request time on the basis of the first frame, and transmits the second frame to the authentication information device. The authentication information device generates time authentication information based on the request time included in the received second frame, generates a third frame including the generated time authentication information, and transmits the third frame to the transmission network.
