Abstract

The invention discloses a method for recovering system software in network terminating equipment. The method comprises the following steps that: a communication protocol and a backup strategy of the network terminating equipment are set between the network terminating equipment and customer premises equipment; the network terminating equipment transmits system software thereof needing backing up to the customer premises equipment for backup according to the set backup strategy and communication protocol when working normally; and a boot loader downloads the required system software from the customer premises equipment according to the set communication protocol when the network terminating equipment detects that the system software needs recovering at the boot loader of the network terminating equipment. The invention discloses a system for recovering the system software in the network terminating equipment at the same time. Through the scheme of the invention, a user can independently realize the recovery of the system software of the network terminating equipment and the method and the system have the advantages of simple method, convenient operation and capacity of saving the maintenance cost of the network terminating equipment.

Description

technical field

[0001] The invention relates to computer network and embedded system system restoration technology, in particular to a method and system for restoring system software in network terminal equipment. Background technique

[0002] At present, network terminal devices such as home gateways have begun to become popular. These network terminal devices are connected to user terminal devices, such as personal computers (PCs) and personal digital assistants (PDAs), through Ethernet (ETH), wireless fidelity (Wifi), and universal serial bus (USB) ), etc., while on the wide area network (WAN) side, it is connected to the Internet (Internet) through digital subscriber loop (DSL), ETH, passive optical network (PON), etc., thus providing user terminal equipment with the function of accessing the Internet. Most of these network terminal devices are embedded system devices, usually using flash memory (flash) as a non-volatile storage device, and the flash is divided into sev...
