Unix, portable operating system Unix) and the operating system of the multi-user of Unix, multitask, multithreading and multi-CPU.Nowadays,
Through there being many hardware devices to be mounted with full release or the linux system of cutting version, such as: home gateway, mobile phone, flat board electricity
Brain, computer, large server etc..
Home gateway based on Linux is as user's lateral terminal product of a integration of three networks, and application is more and more extensive, needs
Ask more and more.Engineering has been frequently encountered by high-volume (10,000 or more multiple stage) new equipment, for a certain reason, equipment outside
When being stored in warehouse, before being applied to domestic consumer, need again upgraded version or configuration.Do not possessing EMS
(Element Management System, graphic network manager system) platform or RMS (Remote Management System, far
Thread management system) platform, under conditions of uniquely possessing the PC of WINDOWS operating system, need manually every equipment to be risen
Level, had both expended time also labor intensive.
The gateway device batch upgrade scheme of current published linux system has: batch upgrade based on multicast or base
Broadcast in UDP (User Datagram Protocol, UDP) is upgraded.Both schemes are primarily present following
Three point defects:
(1) there is the incomplete problem of gateway client file reception.
Upgrading based on udp protocol does not supports burst to retransmit and verification, there is no assurance that each data that PC sends are divided
Sheet, gateway can be properly received, it is difficult to ensures that gateway client receives the complete of file and correctness.
(2) have that to take greater room, the failed probability of upgrading bigger.
Two kinds of traditional upgrading modes: the first, by FTP order, upgrade file is transferred to equipment FLASH subregion, and
In file reads internal memory in FLASH, then complete escalation process by calling upgrade interface, and upgrade interface was being upgraded
Needing to distribute the interaction process that correspondence memory completes User space and kernel state in journey, therefore this scheme needs one times of upgrade file big
Little FLASH space and the DDR space of twice upgrade file size, relatively consumption FLASH and DDR resource；The second, is ordered by FTP
Upgrade file is transferred to equipment DDR space by order, and is read by file in DDR space, and this scheme needs three times of upgrade files big
Little DDR space, bigger to DDR resource requirement；
Two kinds of traditional upgrading modes need the remaining space of more than at least 2 times mirror image sizes to supply upgrading, by embedded system
System FLASH size limits, and causes the probability that upgrading is failed bigger.
(3) traditional escalation process does not has verification scheme, causes escalation process the most intelligent, and upgrading starts and terminate mark nothing
Method confirms.

Method, comprises the following steps:
S1, service end pass through raw socket, self-defined message form, and the layer 5 application layer of extension ICP/IP protocol is led to
Letter mutual message, sets up the two-way communication of cross-platform service end-client, and service end uses WINDOWS system, and client is adopted
Use Linux embedded system；
Owing to WINDOWS system does not allow user to send self-defined L 2 broadcast bag, and Linux embedded system allows to use
Family sends self-defined L 2 broadcast bag, so needing to set up cross-platform two-way communication by raw socket.
S2, service end dynamically distribute unique ip address to the client found, set up TCP (Transmission
Control Protocol, transmission control protocol) connect；
S3, service end verification client, the need of upgrading, if need not upgrading, then terminates；If needing upgrading, visitor
Family end rewrites the file transfer protocol (FTP) defined in linux system kernel ICP/IP protocol, such as: wget
(WorldWideWebget), FTP (File Transfer Protocol, file transfer protocol (FTP)) etc. order, by file fragmentation spelling
After being connected into block, it is stored directly in internal memory.Wget is a free instrument automatically downloading file from network, supports to pass through
Tri-modal ICP/IP protocols of HTTP, HTTPS, FTP are downloaded, it is possible to use HTTP Proxy.
Shown in Figure 2, in step S2, service end dynamically distributes unique ip address, sets up TCP even to the client found
The process connect is as follows:
Service end startup finds thread automatically, cycles through the discovery message of broadcast udp protocol, and carries at data field
Service end MAC (Medium Access Control, medium access control) address；
When client receives the discovery message that service end sends, report the MAC Address of oneself, request distribution IP address；
Service end uses loop distribution algorithm, dynamically distributes unique ip address to the client of different MAC Address found:
The service end client to all connections, safeguards a facility information chained list, if finding client in facility information chained list
MAC Address, and IP address pool have the IP address of correspondence, then client is distributed in this IP address；Otherwise, in IP address pool
Distribute new IP address to client, and this IP address of labelling takies in IP address pool；
Loop distribution algorithm: if the IP address of service end is a.b.c.d (1≤d≤254), then distribute to client same
The IP address range of the network segment is [a.b.c.1]-[a.b.c. (d-1)] and [a.b.c. (d+1)-[a.b.c.253], has 253
IP address.Initialize IP address pool array ip_pool [index] all 0.In IP address pool, labelling service end has taken
IP address be 1 (ip_pool [d]=1).
For example, with reference to shown in Fig. 3, service end IP address is 192.168.1.100, then the IP address space section distributed is
192.168.1.1 to 192.168.1.253, and get rid of this IP address of 192.168.1.100.
Client, according to the IP address distributed and designated ends slogan, is set up TCP with service end and is connected.
The embodiment of the present invention relates generally to following three kinds of mutual message:
1. broadcasting packet.Service end sends broadcast UDP message message, carries service end in UDP message message content field
MAC Address, in order to client replys data message according to this MAC Address；
2. request message.Client sets up original Socket socket, assembles UDP unicast message, the purpose MAC ground of transmission
Location is service end MAC Address, carries self MAC breath, request distribution IP address in UDP message message content field.
3. distribution IP address message.Service end broadcast transmission UDP distribution IP address message.At broadcast UDP message data report
Word section, carries certain client uniquely identified MAC information and IP address of distribution, after client receives broadcasting packet, root
The IP address of oneself whether it is allocated to according to the MAC information checking carried in message.
Shown in Figure 4, in step S3, service end verification client is as follows the need of the process of upgrading:
After setting up TCP connection, in service end input validation information, such as service end URL (Uniform Resource
Locator, URL), filename, the whether information such as mandatory upgrade, software version number, service end opens FTP clothes
Business, client reports whether mirror image compilation time and configuration version number, the reply of client waiting for server upgrade, if in regulation
Not replying within time (such as 9 seconds), then time-out, if time-out reaches certain number of times (such as 3 times), client circulation reports
Information wait for a period of time (such as 3 seconds)；Service end judges whether to need updating client, if need not upgrading, and service
End is identified by lighting；If needing upgrading, service end issues upgrading URL, filename etc. to client, and client is carried out
Upgrading: rewrite the file transfer protocol (FTP) in ICP/IP protocol: wget, ftp etc. order, download file, by socket sliced transmission,
Splicing preserves within the data block, and calls upgrade interface, and finally, client is to service end uploaded state information, such as: TCP is even
Connect failure, transmission time-out, receive time-out, without upgrading, upgrading successfully.
The embodiment of the present invention rewrites wget order and ftp order, by sliced transmission socket to internal memory, and upgrade interface
Wget can be directly used to be saved in file cache block.Compared to conventional method, by file read-write interface (fopen,
Fread, fwrite) file is read as cache blocks for interface interchange, it would be desirable to expend the upgrading memory headroom of 2 times, without extra
File reads space.Size space based on embedded system FLASH limitation reason, the embodiment of the present invention can effectively reduce liter
The probability that level is failed.After rewriting wget order, upgrading will only need the upgrade file memory headroom of a times, it is possible in saving
Depositing space, the probability making upgrading failed reduces further.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these amendments and change
Type is within the scope of the claims in the present invention and equivalent technologies thereof, then these amendments and modification are also in protection scope of the present invention
