Abstract: A method for controlling the IoT devices and an IoT system using the same are provided. The IoT devices includes a trigger device and a functional device. A managing software is executable on a client device. First, a credential is sent to the client from the functional device. Second, a script is received at the trigger device. The script includes the credential, at least one supported command, and at least one supported event. The script is generated at the managing software. The supported command is recognizable to the functional device. When the supported event is triggered at the trigger device, the supported command from the trigger device is received at the functional device. Then, a function of the functional device is performed based on the command, which increases the convenience of operating the system. The trigger device need not recognize the command, which increases the flexibility of the system.

Abstract: A network-traversal method includes: receiving an address information of a network device from a link server; generating a port number sequence composed of port values according to an external port number of the address information; and sending a link packet to an external network address of the address information in an order of the port values in the port number sequence until receiving an acknowledgement packet from the network device. At least one of the port values is related to the external port number. A part of the rest port values is/are generated gradually based on the external port number, and the others of the rest port values is/are generated randomly.

Abstract: A establishing method for a P2P connection includes: receiving a connection request with a remote device from a client device, detecting a validation token in a network packet from the client device according to the connection request, and when the validation token is detected to be valid, executing a connection validation procedure including: receiving a first validation code and a first address information from the client device, reading a second validation code and a second address information from a storage unit, sending the first validation code and the first address information to the remote device, and sending the second validation code and the second address information to the client device. Therefore, the P2P connection between the client device and the remote device is established according to the first validation code, the second validation code, the first address information and the second address information.
