Abstract: A communication method for keeping network connection of an electronic device in a sleep mode includes connecting an address translator to an electronic device via a local network, connecting the address translator to a server via an internet network, providing a connection channel between the electronic device and the server by using the address translator, sending a first keeping-connection request from the electronic device to the address translator before the electronic device gets into a sleep mode, and keeping freely flowing of the connection channel according to the first keeping-connection request by using the address translator when the electronic device is in the sleep mode.

Abstract: A method of effective retaining of NAT channel service is provided. The method is applicable to a network system comprising at least one intranet device, a NAT network device and at least one server, in which the NAT network device is allocated with a plurality of NAT channel ports. The intranet device operates a process for detecting a valid period of the NAT channel with respect to the server via the NAT channel ports. The intranet device periodically transmits a packet, within the valid period of the NAT channel, to the server via the NAT channel ports so as to allow each NAT channel to constantly retain active to provide network transmission service.

Abstract: When a first device is establishing a point-to-point connection with a second device, a server provides connection instructions for assistance. The connection instructions define multiple connection flows. When the connection instructions are received, the first device attempts a first connection flow under a priority order. If failed, another connection is tried by the first device. The server monitors connection status and adjusts the connection instructions according to statistics and circumstances.

Abstract: In a machine-implemented method for assisting labeling of correct product selling prices on a shopping website, upon receipt of an input of a product name and a selling price of a product, a network interface program is enabled to search a specific shopping website for selling prices of related product items. An average selling price of the related product items thus located is found, and a determination as to whether a difference between the inputted product selling price and the average selling price is greater than a preset value is made. Acceptance of the inputted product selling price is refused and a warning message is issued if affirmative. The inputted product selling price is accepted and stored if otherwise. Accordingly, an operator of the shopping website can be assisted to detect pricing errors so as to prevent labeling of incorrect product selling prices due to oversight.

Abstract: A method for managing a shopping website for preventing surging ordering products includes counting orders of a certain product during a predetermined duration, and then denying the ordering of the certain product if the orders of the certain product exceed a predetermined amount during the predetermined duration.
