Abstract: An image file packaging method is applied to a first device. The first device comprises a storage device and a first processor. The image file packaging method includes: the first device receives a kernel image wherein the initial kernel header is located in the kernel image; an initial application and the kernel image are stored in the storage device; and the first processor executes a hash tree generation program. The hash tree generation program performs the following steps: calculating an initial hash tree of the initial application to obtain an initial root node, and embedding the initial root node into the initial kernel header to generate a new version kernel header.

Abstract: The present invention provides a router including first and second wide-area network interfaces, at least one local area network interface, and a control unit. The local area network interface is electrically connected to at least one electronic device through at least one local area network. The control unit enables the electronic device to have at least one network service of the Internet through the first and the second wide-area network interfaces and the local area network interface, and assigns the network service to the first wide-area network interface or the second wide-area network interface according to at least one condition of the network service, wherein the condition includes at least one packet rate caused by the network service.
