COMMUNICATION CONTROL APPARATUS AND COMMUNICATION CONTROL METHOD
First Claim
1. A data transmission control server, comprising:
- a network interface connected to a network and communicating with a data transmission server, a data transmission auxiliary server, and a client via the network, wherein the data transmission server and the data transmission auxiliary server transmit data to the client based on a client request;
a data transmission information database having stored therein a data identifier for identifying transmission data, a data transmission address for specifying an address of the transmission data, and a data transmission beginning time indicative of a beginning time of data transmission; and
a control unit that controls the data transmission server and the data transmission auxiliary server so as to transmit data to the client by transmitting transmission data session information to the data transmission server and the data transmission auxiliary server based on a data transmission request from the client.
