A data transmission device is provided which can transmit data directed to a specific individual to a terminal in the vicinity of the specific individual. When a transmission event of data occurs, position data table of terminals, which the specific individual has a possibility to use, on a network is searched to extract the position data which coincides with or is the closest to the position of the specific individual at a present time or at an arbitrary time point in a given time period including the present time. The data is transmitted to a terminal corresponding to the extracted position data. Therefore, data can be transmitted to a terminal which is located in the vicinity of a specific individual and immediate accessibility of data transmission can thereby be improved.

The method of claim 1, wherein the network includes a broadcast network configuration. 3. The method of claim 2, further comprising: upon determining that the transmitting network element is a designated network element for the network, performing the following until a preset timer has expired: transmitting a request for routing data using a Link State Packet (LSP) under the International-System-International-System (IS-IS) standard to the number of receiving network elements; receiving routing data from the number of receiving network elements; and updating routing data within the transmitting network element based on the received routing data; and resuming operation upon determining that the preset timer has expired. 4. The method of claim 1, wherein the network includes a point-to-point configuration. 5. A machine-readable medium that provides instructions for restarting communication between a transmitting network element and a number of receiving network elements in a network, which when executed by a machine, causes the machine to perform operations comprising: generating, by the transmitting network element, a hello packet, the hello packet to include a time value, the time value to indicate when hello packets that are transmitted by the transmitting network element are to be received by the number of receiving network elements; generating, by the transmitting network element, a copy of the hello packet; increasing, by the transmitting network element, the time value in the copy of the hello packet; storing, by the transmitting network element, the copy of the hello packet in a local memory; and transmitting, by the transmitting network element, the copy of the hello packet to the number of receiving network elements when the transmitting network element is reinitializing after International-System-International-System (IS-IS) network communications in the transmitting network element have been non-operational. 6. The machine-readable medium of claim 5, wherein the network includes a broadcast network configuration. 7. The machine-readable medium of claim 6, further comprising: upon determining that the transmitting network element is a designated network element for the network, performing the following until a preset timer has expired: transmitting a request for routing data using a Link State Packet (LSP) under the International-System-International-System (IS-IS) standard to the number of receiving network elements; receiving routing data from the number of receiving network elements; and updating routing data within the transmitting network element based on the received routing data; and resuming operation upon determining that the preset timer has expired. 8. The machine-readable medium of claim 7 wherein the network includes a point-to-point configuration. 9. A network element comprising: a control card including a heartbeat unit, the heartbeat unit having stored thereon a set of instructions for restarting communication between the network element and a receiving network element, the set of instructions to cause the heartbeat unit to, generate a hello packet, the hello packet to include a time value, the time value to indicate when hello packets that are transmitted by the network element are to be r
