Network terminal, communication method, and program

A network terminal comprising:

• a communication unit configured to communicate with a device with which the network terminal communicates through a communication path;
• and
• a control unit configured to cause the communication unit, by controlling the communication unit, to transmit to the device a communication packet for maintaining the communication path at a transmission timing in every predetermined interval,
• wherein by controlling the communication unit, the control unit is further configured to cause the communication unit to
• transmit an information packet to the device through the communication path even at a time different from the transmission timing, if a terminal state of the network terminal is changed, and
• determine a new transmission timing for the communication packet in each predetermined interval, starting from a moment at which the communication unit has transmitted the information packet, the information packet being a communication packet obtained by storing terminal state information indicative of the terminal state into the communication packet for maintaining the communication path.
