Technical field
The present invention relates to cross-platform communication between devices fields, are specifically related to a kind of based on WINDOWS and LINUX platform
Gateway batch upgrading method and system.
Background technique
Linux system is a kind of based on POSIX (Porttable Operation System Interface of
Unix, portable operating system Unix) and the multi-user of Unix, multitask, multithreading and multi -CPU operating system.Nowadays,
Full release is mounted with there are many hardware device or cuts the linux system of version, such as: home gateway, mobile phone, plate electricity
Brain, computer, large server etc..
User side end product based on the home gateway of Linux as a integration of three networks, application is more and more extensive, needs
Ask also more and more.Engineering has frequently encountered high-volume (10,000 or more) new equipment, for some reason, equipment outside
When storing in warehouse, before being applied to domestic consumer, upgraded version again or configuration are needed.Do not having EMS
(Element Management System, graphic network manager system) platform or RMS (Remote Management System, far
Thread management system) platform, under conditions of the PC for uniquely having WINDOWS operating system, need manually to rise every equipment
Grade, had both expended time or labor intensive.
The gateway batch upgrade scheme of current published linux system has: batch upgrade or base based on multicast
Upgrade in the broadcast of UDP (User Datagram Protocol, User Datagram Protocol).Both schemes are primarily present following
Three point defects:
(1) there are the incomplete problems of gateway client file reception.
Upgrading based on udp protocol does not support fragment to retransmit and verify, there is no assurance that each data point that PC is sent
Piece, gateway can be properly received, it is difficult to guarantee that gateway client receives the complete and correctness of file.
(2) it is larger to there is occupancy greater room, the probability of upgrading failure.
Two kinds of traditional upgrading modes: the first, upgrade file is transferred to by equipment FLASH subregion by FTP order, and
File in FLASH is read into memory, then by calling upgrade interface to complete escalation process, and upgrade interface was upgrading
Need 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
FLASH and DDR resource is relatively consumed in the space DDR in the small space FLASH and twice of upgrade file size；It second, is ordered by FTP
It enables and upgrade file is transferred to the space equipment DDR, and file in the space DDR is read, this scheme needs three times upgrade file big
The small space DDR, it is larger to DDR resource requirement；
Two kinds of traditional upgrading modes need the remaining space of at least 2 times or more mirror image size for upgrading, by embedded system
FLASH size of uniting limitation, the probability for causing upgrading to fail are larger.
(3) traditional escalation process does not have verification scheme, leads to escalation process not intelligence, and upgrading beginning and end identifies nothing
Method confirmation.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, provide a kind of flat based on WINDOWS and LINUX

Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in further detail.
The embodiment of the present invention provides a kind of gateway batch upgrading system based on WINDOWS and LINUX platform, the system packet
Server-side and client are included, server-side uses WINDOWS system, and client uses Linux embedded system.
Shown in Figure 1, the embodiment of the present invention provides a kind of gateway batch upgrade based on WINDOWS and LINUX platform
Method, comprising the following steps:
S1, server-side pass through raw socket, self-defined message format, and the layer 5 application layer for extending ICP/IP protocol is led to
Believe mutual message, establish cross-platform server-side-client two-way communication, server-side uses WINDOWS system, and client is adopted
With Linux embedded system；
Since WINDOWS system does not allow user to send customized L 2 broadcast packet, and Linux embedded system allows to use
Family sends customized L 2 broadcast packet, so needing to establish cross-platform two-way communication by raw socket.
S2, server-side dynamically distribute unique ip address to the client of discovery, establish TCP (Transmission
Control Protocol, transmission control protocol) connection；
Whether S3, server-side verification client need to upgrade, if you do not need to upgrading, then terminate；If necessary to upgrade, visitor
Family end rewrites File Transfer Protocol defined in linux system kernel ICP/IP protocol, such as: wget
(WorldWideWebget), FTP (File Transfer Protocol, File Transfer Protocol) etc. is ordered, and file fragmentation is spelled
After being connected into block, it is stored directly in memory.Wget is the free tool for downloading file automatically from network, supports to pass through
HTTP, HTTPS, FTP tri- most common ICP/IP protocol downloadings, and HTTP Proxy can be used.
Shown in Figure 2, in step S2, server-side dynamically distributes unique ip address to the client of discovery, establishes TCP company
The process connect is as follows:
The automatic discovery thread of server-side starting cycles through the discovery message of broadcast udp protocol, and carries in data field
Server-side MAC (Medium Access Control, medium access control) address；
When client receives the discovery message of server-side transmission, the MAC Address of oneself, request distribution IP address are reported；
Server-side uses loop distribution algorithm, dynamically distributes unique ip address to the client of the different MAC Address of discovery:
Server-side safeguards a facility information chained list to the client of all connections, if finding client in facility information chained list
MAC Address, and have corresponding IP address in IP address pond, then the IP address is distributed into client；Otherwise, in IP address pond
New IP address is distributed to client, and mark the IP address to occupy in IP address pond；
Loop distribution algorithm: if the IP address of server-side is a.b.c.d (1≤d≤254), then it is same to distribute to client
The IP address range of network segment is [a.b.c.1]-[a.b.c. (d-1)] and [a.b.c. (d+1)-[a.b.c.253], shares 253
IP address.Initialize IP address pond array ip_pool [index] all 0.Server-side is marked to occupy in IP address pond
IP address be 1 (ip_pool [d]=1).
For example, with reference to shown in Fig. 3, server-side 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 this IP address of 192.168.1.100 is excluded.
Client establishes TCP connection with server-side according to the IP address and designated ends slogan of distribution.
Following three kinds of mutual messages are related generally in the embodiment of the present invention:
1. broadcasting packet.Server-side sends broadcast UDP message message, carries server-side in UDP message message content field
MAC Address, so that client replys data message according to this MAC Address；
2. request message.Client establishes original Socket socket, assembles UDP unicast message, the purpose MAC of transmission
Location is server-side MAC Address, carries self MAC breath, request distribution IP address in UDP message message content field.
3. distributing IP address message.Server-side broadcast transmission UDP distributes IP address message.In broadcast UDP message data report
Text section carries the MAC information of certain client unique identification and the IP address of distribution, after client receives broadcasting packet, root
The IP address of oneself whether is allocated to according to the MAC information checking carried in message.
Shown in Figure 4, in step S3, the process whether server-side verification client needs to upgrade is as follows:
After establishing TCP connection, in server-side input validation information, such as server-side URL (Uniform Resource
Locator, uniform resource locator), filename, whether the information such as mandatory upgrade, software version number, server-side opens FTP clothes
Business, client report mirror image compilation time and configuration version number, and whether the reply of client waiting for server upgrades, if providing
It is not replied within time (such as 9 seconds), then overtime, if time-out reaches certain number (such as 3 times), client circulation is reported
Information simultaneously waits for a period of time (such as 3 seconds)；Server-side judges whether to need updating client, if you do not need to upgrading, service
End is identified by lighting；If necessary to upgrade, server-side issues upgrading URL, filename etc. to client, and client carries out
Upgrading: rewrite the File Transfer Protocol in ICP/IP protocol: file is downloaded in the order such as wget, ftp, by socket sliced transmission,
Splicing saves within the data block, and calls upgrade interface, finally, client is to server-side uploaded state information, such as: TCP connects
It connects failure, transmission time-out, receive time-out, without upgrading, upgrading successfully.
The embodiment of the present invention rewrites wget order and ftp order, through sliced transmission socket into memory, upgrade interface
It can be directly saved in file cache block using wget.Compared to previous method, by file read-write interface (fopen,
Fread, fwrite) it file is read as cache blocks is called for interface, it will need to expend 2 times of upgrading memory headroom, without additional
File reads space.Size space limitation reason based on embedded system FLASH, the embodiment of the present invention can be effectively reduced liter
The probability of grade failure.After rewriting wget order, upgrading will only need one times of upgrade file memory headroom, can save interior
Space is deposited, the probability for making upgrading fail further decreases.
Those skilled in the art can carry out various modifications to the embodiment of the present invention and modification, if these modifications and change
For type within the scope of the claims in the present invention and its equivalent technologies, then these modifications and variations are also in protection scope of the present invention
Within.
The prior art that the content being not described in detail in specification is known to the skilled person.
