Description
Technical field
It is extensive using router guiding system remote more particularly to one kind the present invention relates to the technical field that router recovers
The system and method for multiple router.
Background technology
Similar to computer system, route system can encounter abnormal power-down, start exception unavoidably during day-to-day operation
Situations such as.Computer system can realize that system is reset by measures such as boot cd-roms, but router is due to space limitation and system
Ability, after there is starting exception often can only depot repair, used to user and producer safeguard bring it is very big constant.
In the prior art, in order to prevent route system damage the following two methods of generally use：
(1) router dual system is built
Router newly-built subregion in Flash spaces, specially deposits standby system.Each route system is restarted
When, it is both needed to detect whether primary subregion damages, starts if damage from spare partitions；Standby system is copied to after into system
Primary subregion.Although this method can be efficiently solved due to router can not start caused by system failure the problem of,
It needs extra increase Flash spaces, and needs to detect active and standby subregion before every time starting, and causes the startup time elongated.If
Active and standby subregion damages simultaneously, and the problem of cannot be introduced into system still occurs.
(2) router firmware is upgraded manually
Increase web interface in router guiding system uboot, in router startup exception by accessing web interface
Manual firmware updating recovers.But this method needs manually to obtain firmware, and it is typically the method or interface hidden, commonly
User is difficult come restoration route device by the method.
In summary, existing router restoration methods are primarily present following shortcoming：
1) extra increase Flash spaces are needed；
2) can not recover when active and standby subregion damages；
3) need to download router firmware in advance；
4) domestic consumer is difficult operation.
The content of the invention
In view of the above the shortcomings that prior art, it is an object of the invention to provide one kind to utilize router guiding system
The system and method for remote recovery router, in the case of router startup exception, system (uboot) is guided by router
The automatic configuration information for obtaining router, and into network, fixed position obtains corresponding router firmware automatically, without people

Firmware subregions 3 are arranged on the FLASH of router, for depositing router firmware.
Firmware server 1 is used for the firmware for storing router.
When router startup exception, router rests on guiding system (uboot), configures in subregion and reads from NVRAM
Router WAN mouths are set, and are set further according to WAN mouths to firmware server and are downloaded router firmware with automatic restoration route device.
Preferably, the router firmware of download is backuped in firmware partition, to ensure the normal startup of router next time.
In a preferred embodiment of the invention, in router guiding system (uboot) embedded dhcpc and
This 2 processes of pppoecd.When router startup exception, configured from NVRAM and WAN mouth configuration informations are obtained in subregion, initiated
DHCP or PPPoE dialing, get behind address again to router firmware corresponding to downloading on fixed server, so as to automatic real
The recovery of existing router.
In summary, it is of the invention to guide the system and method for system remote restoration route device by router using router
Guiding system (uboot) downloads router firmware and writes current Flash spaces automatically, without increasing extra Flash
Space, reduce router hardware cost；Configuration of routers is stored in NVRAM configuration subregions, not influenceed by firmware partition；Work as road
When being damaged by device firmware partition, the route configuration informations such as WAN mouths are set are unaffected, can be by router boot partition
(uboot) call；It is automatic to obtain address and download router firmware when router startup exception, without manual intervention；Need not
Router is downloaded in advance recovers firmware.So the present invention effectively overcomes various shortcoming of the prior art and has high industrial
Value.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
