Embodiment
Fig. 2 is the block scheme of the browser software storehouse 208 of self-contained permanent storage.Browser software storehouse 208 is by permanent storage, but is not to be stored on traditional electromagnetism hard disk." the electromagnetism hard disk " of Shi Yonging is magnetic storage medium herein, is commonly referred to disc, and it can mechanical rotation.Read-write operation is finished by a read/write head as the part of this hard disk.
Preferably, browser 208 is stored among the PCBIOS of ROM (ROM (read-only memory)) 212, or ROM equivalent, for example electrically programmable read only memory (EPROM), electronics Erarable Programmable Read only Memory (EEPROM), electronics can be rewritten programmable read only memory (EAPROM), dodge Erarable Programmable Read only Memory (FLASH or FEPROM).The PC BIOS representative of herein using " personal computer Basic Input or Output System (BIOS) ".PC BIOS is the firmware code of the storage area of permanent storage on personal computer.It mainly is responsible for carrying out the low layer input-output operation, represents operating system usually.But according to one embodiment of present invention, PC BIOS has comprised self-contained browser software storehouse 208.
The operation general view
Fig. 3 be browser 300 at electronic hardware, for example personal computer (Fig. 6 represents an embodiment of personal computer) is gone up the high-level block diagram of operation.According to one embodiment of present invention, the personal computer (hereinafter claiming computing machine 300) that contains browser software is carried out four kinds of basic operations at least.A kind of operation comprises the I/O function.In order to reach this purpose, computing machine 300 contains a load module 304.Load module 304 comprises hardware, and it provides one or more and external unit, for example the communication mode of keyboard, mouse, writing pencil or touch-screen.Serial ports, the I/O controller, USB port, IEEE 1394 ports and CEBus are the examples of communication mode.Be included in software processes interruption, buffer memory and input distribution command and control in the browser for receiving by communication mode.Should be noted that by the communication mode of load module 304 and also can handle output, although this is not the major function of load module 304.
Another operation of computing machine 300 is lower layer network communication.For this reason, provide a network communication module 308 to handle communication function and operation, this processing is to carry out on Physical layer, data link layer, network layer and the transport layer in 7 layers of OSI (open system interlink) reference model that for example networking technology area is known.
The hardware device that can carry out network communication module 308 comprises Ethernet card, traditional landline modulator-demodular unit, cable modem and radio modem.As many Internets RFC (Multiple Internet RFCs) of the standard of the Internet, defined the software specifications that allows these hardware devices operations.According to embodiments of the invention, the Internet RFC comprises 791 (Internet Protocols, or IP), 792 (Internet Control Message Protocols, or ICMP), 793 (transmission control protocol or TCP), 826 (address resolution protocol or ARP), and 1661 (peer-peer protocols, or PPP), all these can obtain on the Internet, and URL is http://www.pmg.lcs.mit.edu/rfc.html.
The third operation of computing machine 300 is to handle from and to data that reach network communication module 308 and control.In network application module 312, the employing variety of protocol is explained the message from network communication module 308, and provide special client (or user interface) (for example to give them, terminal monitor software or email client), perhaps visit other client disparate modules (for example the page is presented module 316, and this module will be described below).If network application module 312 provides client to the user, so except handling from and to the data that reach network communication module 308, it can also receive the data from load module 304---and perhaps directly receive, perhaps pass through another module, for example the page is presented module 316 receptions.
The typical case of network application module 312 uses (or agreement) DNS (domain name system Domain Name System), HTTP (HTML (Hypertext Markup Language) Hypertext TransferProtocol), SSL (security socket layer), HTTPS (secure HTTP), SMTP (Simple Mail Transfer protocol), POP3 (mailbox protocol version 3), TELNET, and FTP (file transfer protocol (FTP)).These network applications further are described as in the Internet RFC: 1034 (DNS), 2068 (HTTP), 821 (SMTP), 1081 (POP3), 854 (TELNET) and 959 (FTP).At present preferably, only realize SMTP simultaneously in network application module 312, POP3, DNS, HTTP, SSL and HTTPS.Usually, the agreement that comprises in the browser is few more, as a result areal coverage just more little (promptly the needed amount of memory of this self-contained web browser of storage just reduces).
At the top of this block scheme is that the page is presented module 316.The page is presented module 316 and is handled HTML (HTML) document that transmitted and the explanation of other document formats.For example, the page is presented module 316 and is presented graphic file, carries out page layering subroutine, and handles the window's position, size and rolling with response from the data of load module 304 data of mouse (for example, from).The page is presented module 316 and the direct communication of display module (not shown).
Module is described in detail
Fig. 4 is the detailed functional block diagram of this self-contained web browser.Fig. 4 is according to finally being presented at the display of computing machine to it from network (for example, passing through peripherals) or the typical data stream on the terminal is organized.Although the function of various detailed modules (Fig. 4) can move between general purpose module (Fig. 3), when describing herein all with reference to specific general purpose module.For example, load module 304 (Fig. 3) comprises software module 408 to 412.In one embodiment, network communication module 308 comprises software module 416 to 432, and network application module 312 comprises software module 436 to 464, and the page is presented module 316 and comprised software module 468 to 482.
Data inputs is received by peripherals 404 (promptly being increased to inside or external unit on the computing machine 300, Ethernet card for example, keyboard, mouse, or wire/wireless modulator-demodular unit).After data were transfused to module 304 receptions, it is sent to specific modules from one or more computing machine I/O (I/O) interface processed.In general, each peripherals is endowed a specific I/O port, causes interruption at real-time kernel with the data communication of peripherals, further specifies with reference to Fig. 2 below.This interrupts the memory address of certain unusual vector of sign or a kind of algorithm, and this algorithm process is from the input data of peripherals.For example, can trigger first serial from the signal of modulator-demodular unit and interrupt, then cause modulator-demodular unit point-to-point (PPP) protocol module 416 to be activated.
Before the single component of key diagram 4 more detailed block diagram, will be appreciated that debugging control platform (debug console) module 412 is unwanted.Debugging control platform module 412 is used as and is used to reach software and hardware test purpose debug port.In addition, the element of representing with solid line is the part of browser software, and the element that dots is the part of whole personal computer when carrying out browser software.
In addition, physical page (at a high speed) buffer memory 490 and display 494 are not the parts of browser software storehouse.Page cache 490 preferably adopts volatile memory, as one or more network applications data be passed to the page present module 472 before the buffer zone of deal with data use.For example, page cache 490 can be stored them in advance before html file (comprising file that explain and that do not explained) is passed to display 494.Display 494 can be that the page is presented the peripherals that module 472 is communicated by letter with it, also can be the volatile storage buffer zone that the actual displayed equipment of data is provided to the user.Display 494 receives the data of presenting module 472 from the page.
In addition, ROM file 468 neither necessary (although they be preferred).ROM file 468 energy one or more user's diagnose interfaces of permanent storage or templates, the latter is used for diagnosing the problem of personal computer by specific long-range supplier (for example, computer maker or Internet service provider).For example, when browser is connected to long-range supplier, just can be stored in the diagnostic routine of maybe can carrying out of employed HTML form in the ROM file 468.Although they are called as the ROM file, these files can be stored in electronics and can rewrite among the ROM, for example flash memory (FLASH memory).Is Cookie (cookies) or other file storage useful in ROM file 468, the static file fully because cookies is not inevitable, but taking place at any time to change.
Cursor control module 408 is used to handle the data from mouse or writing pencil input.These data normally with the corresponding bidimensional mobile data of mouse moving.These data also comprise control signal, and for example the mouse selector switch is clicked.Cursor control module 408 preferably receives data from serial port, but it also can be from radio port, and for example infrared port receives data.
Keysheet module 410 is keyboard drivers.It is used to input or keys in text and present module 472 to form and/or direct input command to the page, and presents other module that module 472 interfaces are connected with the page---and for example module 452 to 464.The importance of Keysheet module 472 is its abilities that start browser.Usually, the user imports certain particular key or key sequence (for example, CTRL-ALT-B or CTRL-ALT-HOME) manually starts this self-contained browser, thereby gets around the normal manipulation mode of personal computer.Usually, the particular key sequence only just activates when personal computer starts.Keysheet module 410 also is used to control the page and rolls and the zone selection, for example uses directionkeys and/or TAB key on the keyboard.
The purpose that debugging control platform 412 is used to debug comprises that the main effect of this debugging control platform 412 is software adjustment.For example, because device driver is different for chipset on different computing machines and hardware device, on one or more new hardware devices, move so just can use debugging control platform 412 to monitor browser.Debugging control platform 412 is not the necessary assembly of this browser software.
Modulator-demodular unit PPP module 416 is used to handle the bag data that enter from public switched telephone network (PSTN).The function of this module 416 is preferably followed the Internet RFC1616, and configuration is used to help modulator-demodular unit to be connected to Internet service provider (ISP) or access to the Internet supplier (IAP), and sets up virtual the connection with one or more remote servers.Modulator-demodular unit PPP module 416 also comprises the device driver that is used for modulator-demodular unit.
Ethernet ARP module 420 also is used to handle the bag data of automatic network.But this network can be high-speed local area network (LAN), or high-speed wan WAN.Module 420 comprises one or more device drivers that are used for Ethernet card (peripherals).Ethernet ARP module 420 is followed the Internet RFC 826, because this module is configured to do conversion between IP address and ethernet address.
IP/ICMP module 424 connects situation according to network and receives (data) bag from module 416 or 420.The IP section of IP/ICMP module 424 is handled burst, bag is transmitted and the reorganization of IP bag.ICMP is the expansion to IP, and it handles the error message and other information relevant with IP that is produced.The function of IP/ICMP module 424 is consistent with the Internet RFC 791 and 792.
TCP/UDP module 428 installs to the IP package message (message) that is used for network application.TCP/UDP module 428 is according to the Internet RFC 793 (TCP) and the Internet RFC768 (User Datagram Protoco (UDP), or UDP) operation.Because TCP/UDP module 428 and TCP and UDP compatibility, so it both can support connection-oriented communication (TCP), also can support connectionless communication (UDP).
Socket application programming interface (API) module 432 provide as shown in Figure 3 network communication module 308 and the interface between the network application module 312.When network application was carried out on computing machine 300, network application was called subroutine and is sent and receive from and to the data/message that reaches network communication module 308.In order to reach this purpose, socket API432 is used as, and distributor is created or the IP virtual connections of dismounting and remote server, or title " socket ".Because this browser software is supported TCP and UDP simultaneously, thus this socket can be connection-oriented also can be connectionless.
As mentioned above, module 436 to 464 can be classified as the network application module.The network application module communication is connected to socket API 432 and the page is presented in the module 472.
The URL that DNS module 460 is used to the English type of mapping (or resolve) (for example, http://www.elegent.com, wherein " http: // " represent the network application agreement and " www.elegent.com " expression URL) to the IP address (for example, 206.171.12.20).(as mentioned above, Ethernet ARP module 420 mapping IP addresses are to ethernet address) DNS describes in the Internet RFC 1034.DNS module 460 is transmitted domain name request (inquiry) to resolver or name server and according to RFC 1034 processing.
HTTP module 456 is used to HTML (HTML) file is sent to or from certain remote server.Most of html file is finally presented module 472 by the page and is presented to the user.HTTP module 456 and the Internet RFC 2068 compatibilities.
SMPT module 436, POP3 module 440 is all relevant with the processing e-mail message with e-mail module 464.SMTP module 436 comprises the software of handling the e-mail message that is sent according to the Internet RFC 821 (it all is incorporated herein by reference).SMTP module 436 communicates to connect socket API 432 and email client (or e-mail module) 464 (it is the user interface of SMTP and POP3 network application).POP3 module 440 comprises the software of processing from the e-mail message that remote server received.The same with SMTP module 436, POP3 module 440 also communicates to connect socket API 432 and email client 464.E-mail module 464 is the software interface based on HMTL preferably, and it is presented module 472 by the page and explains.
Although SMTP and POP3 are used for two preferred protocol of the present invention, also can adopt other email protocol.For example, e-mail message is in the agreement of remote mail server rather than manipulation on computing machine 300.For example, module 436 and 440 can be replaced by the compatible software of Internet message access protocol (IMAP).The newer version of IMAP describes in the Internet RFC 2060.
FTP module 444 is followed the Internet RFC 959.FTP module 444 handle browsers resident computing machine and the file transfer between the remote server.For the purpose of the present invention, FTP module 444 is not successfully to realize the prerequisite module of browser.
The additional security protocol that SSL module 448 and HTTPS module 452 these browsers of management adopt.When needing to carry out the secure data exchange between this self-contained web browser and the remote server, just activate these modules.When these modules were activated, the private port between browser and the long-range supplier/server (for example port 443) was used to transmit the IP bag.Browser and server are set up the speech channel identifier and are shared one or more keys.Speech channel identifier and key are used for verifying the authenticity of the information that is exchanged, and protect the information that is exchanged to avoid snoopee (the unwarranted user who attempts to eavesdrop communication) and spy upon.For the purpose of the present invention, SSL module 448 and HTTPS module 452 are not successfully to realize the prerequisite module of browser.
Since the network application module has been described, so just come instruction page to present module 472.The page is presented between module 472 and the network application module 312 two-way communication.The data that the page is presented exchange between module 472 and the network application module 312 are cached in the page-buffer 490 usually.The page is presented module 472 and also screen message is sent to display 494, and the latter generally includes and is useful on the graphics accelerator adapter that bitmap shows.The page is presented module 472 and is also received data from one or more input equipments (for example mouse or keyboard).
The page is presented module 472 and is comprised 5 primary elements (part).An element is that figure is presented element 474.Figure is presented element 474 and is explained GIF, JPEG, and the file of MPEG type is to be shown to bitmap display.Figure is presented the also convergent-divergent of processing graphics of element 474.Another element that the page is presented module 472 is a font engine 476.Font engine 476 is supported the employed various fonts of html file.Multilingual element 478 is supported the Character Translation in the html file is become a kind of in numerous language, although browser only need be supported a kind of language.Page layered element 480 is explained the form label in the html files, for example＜bold,＜center and＜color label and＜table and＜frame label.
The window system 482 that the page is presented module 472 provides Windows for each page of presenting to the user or the subframe of html file.The window convergent-divergent of window system 482 processing display 494, and generation level or vertical scroll bar, peripherals can be controlled (by cursor control module 408) to this scroll bar.The motion conditions of cursor control module 408 detected cursors or writing pencil directly sends the page to and presents module 472, particularly is window system 482, is handled.
The browser software architecture
Return Fig. 2, as Fig. 4 self-contained browser software storehouse 208 described in detail, Fig. 2 is its functional-block diagram.This figure is useful to the whole architecture of understanding self-contained web browser, and this web browser is preferably included in the ROM (read-only memory) 212.
Real-time kernel 220 (not illustrating as independent module in Fig. 4) is finished two basic tasks at least.The basic task of real-time kernel 220 comprise that (1) is detected and distributing data arrives or from peripherals to suitable module (2) storage administration.For data processing and distribution, real-time kernel 220 driving wheels are sought peripherals 404, attempt to detect the state variation (for example, whether peripherals share a common bus) of this equipment, perhaps the direct interrupt request sent of kernel 220 passive reception peripherals 404.Real-time kernel 220 is different from traditional operating system part and is the performed low layer task of its processing legacy operating system, but does not handle more high-rise task.On the contrary, more high-rise task reservation is handled by the particular module of this browser 208.
The storage administration aspect of real-time kernel 220 is included in the management of handling in the operational process page cache 490, and to the management of other volatile memory.For example, real-time kernel 220 is carried out following function, for example to each module as shown in Figure 4 employed whole and/or the storage allocation that local storage is regional and the collection of gibberish.
According to one embodiment of present invention, real-time kernel 220 is by three logical storage administration page buffer memorys 490 (Fig. 4).
Request queue zone 491 storage cursors are controlled 408 detected requests and are presented module 472 by the page and are delivered to page cache 490.Request queue zone 491 is also stored by the page and is presented the request that module 472 produces.
492 storages of preprocessed data zone are not also presented the data that module 472 is explained by the page.When in batch HMTL file was obtained in one or more network applications in advance, maybe when just asking a plurality of html file before the explicit request that does not receive the user, pretreatment zone 492 was particularly useful.
The data of being presented module 472 explanations by the page but also not sending to display 494 are preserved in aftertreatment data area 493.Be stored in data in the aftertreatment data area 493 and be delivered to the page from the network application module and present module 472, and present module 472 from the page and be delivered to page cache 490.These data are presented module 472 by page cache 490 from the page once more and are delivered to display 494.
Input and output between the software processing module of real-time kernel 220 processing hardware resources (for example inside and outside equipment/assembly) and computing machine 300.Therefore, real-time kernel 220 is communicated by letter with one or more device drivers 216, and independently nextport hardware component NextPort is relevant with each for the latter, guarantees the initialization of correct communication process and correct nextport hardware component NextPort.
According to an embodiment, real-time kernel 220 communicates to connect on the initialization module (not shown).Initialization module detects each peripherals that is connected on the computing machine 300, and with required initiation parameter format peripherals, and if not success of initialization, this initialization module just triggers one and is used for browser diagnostic process pattern.Like this, the initialization module that browser 208 can be activated the diagnostic process pattern calls, or is called by legacy operating system or terminal user's direct request.In one embodiment, viewed device 208 of this initialization module and legacy operating system are shared.
On Internet Protocol software 224 graphical window software 228.Graphical window software 228 is handled the backstage that shows user's data on display device and is handled.For example, window position, cursor and keyboard input/control, in addition, graphics process is also partly handled by graphical window software 228.
The component software as shown in Figure 2 that operates on the graphical window software 228 is more used near the terminal user.For example, SSL software 236 is handled the security information process.The font software support is shown to terminal user's various font, image software 232 key drawing shape files, and this graphic file also is shown to the terminal user.
Browser starts and diagnostic function
According to one embodiment of present invention, the flowchart text of Fig. 5 A on personal computer, call the step of (enabling) browser.In step 504, the computer system hardware assembly comprises outside and internal unit, all is initialised.In step 508, carry out a test and determine whether browser command or trigger are set up.According to an embodiment, when personal computer starts, call browser command in response to key of importing on the keyboard or key sequence.In another embodiment, physics or CMOS being set is provided with switch and triggers this self-contained web browser.
If do not detect the browser trigger in step 508, thereby personal computer proceeds to step 512 and enters normal manipulation mode so.For example, traditional booting operating system and common purpose application program are performed.Be similar to step 508, in step 516, carry out a test and determined whether that the browser trigger is set up.It should be noted that this process can be handled by certain unusual vector or interruption routine, perhaps it can be handled by certain specific device driver or traditional operating system.If detect the browser trigger, close in step 520 operating system so, and process continues to forward to step 524 in step 516.
Step 524 after step 508 or 520 starts self-contained browser.Fig. 5 B and Fig. 5 C have specified that in a single day this self-contained browser is activated useful various application (program) afterwards.Step shown in Fig. 5 B and 5C is replaced connector " A " (element 528).
Flowchart text shown in Fig. 5 B uses this browser diagnosis and repairs the nextport hardware component NextPort that damages.In step 532, this browser is connected to " long-range " server of network or corresponding certain specific supplier.This supplier can be the company of selling this personal computer, or handles another service provider of the technical service/maintenance of personal computer.Load diagnostic file in step 536, for example be stored in the ROM file 468 file and from the remote server downloaded files.These diagnostic files allow terminal user's type that Reports a Problem, the executive system configuration detection, or diagnose selected nextport hardware component NextPort.Diagnostic file comprises the software code of having explained, executable software code, or HTML interface form for example.Like this, supplier with regard to can remote diagnosis the problem that faces of this personal computer.
Before diagnosis problem, supplier can send order and tell this browser to start a particular diagnosis program, or this supplier can send the diagnostic routine of specific compiling or explanation to this browser.If a diagnostic routine is sent to browser, it is to use FTP, HTTP, HTTPS or smtp protocol to send so.If the use public network, for example the Internet (corresponding with Intranet) just uses authentication (certificate) to verify this diagnostic routine.For example, adopt the RSA data encryption, the authenticity of diagnostic routine is verified in Inc.
