Electronically Erasable Programmable ROM (EEPROM) or Flash Memory. The non-volatile memory 210 includes the operating system and application of the electronic system 200. The program and data in the non-volatile memory 21〇 can be stored in a compressed form and decompressed to the main memory when it is to be executed or used. Referring to Figure 3, the electronic system 200 can include the memory 100A. Memory • Body 100A can be a virtual memory that can actually be mapped to main memory 23 and/or non-volatile memory 210. The memory 100A includes user space and kernel space. The configuration parameter file 12 has a plurality of configuration parameters of the application i〇c, wherein the configuration parameters are used by at least two programs. In order to achieve the purpose of configuration parameter sharing and synchronization, one of the applications of the electronic system 200 (for example, the application l〇c in FIG. 3) starts the parsing procedure for the configuration parameter file 12, and then, according to the configuration parameter file, via the kernel program 13 The relationship between each configuration parameter in 12 to establish a configuration tree (for example, configuration tree 11d) of each configuration parameter in the configuration parameter file 12 in the kernel 8 201007475 of the memory 100A, all the kernels to use the parameters in the configuration tree Ud Program 13 performs a read or modify. Although the actual = data structure is a tree structure, it is not limited to a data structure such as = Γ ο 10 can be combined with a string (1) heart (four). Application: The L i kernel program 13 reads or modifies the parameters in the configuration tree iid, so as to achieve the shame recording sharing and synchronization (4), please refer to Figure 4. In Figure 4, the electronic system has an application group iq, where packet β contains complex applications A1 to An, where n is a positive integer greater than:. An example of the application A1~An may include the application group of the FIG. 3~(10). The electronic system 200 also has an application interface 3, a system call 32 provided by the kernel program 13, a driver 34, and a device file (device me or device special file) 36 ° application interface 30 includes a library, wherein A function containing a plurality of functions for parsing a configuration parameter file (for example, configuration parameter file 12) 'based on the above analysis result to establish a function corresponding to the configuration tree, φ, and a function for modifying and reading the configuration tree and its parameter values formula. Since the configuration tree is in kernel space, the application interface 30 function can utilize the system call (such as "ioctl") provided by the kernel program 13 to drive the kernel program 13 to actuate the driver 34 to complete the setup or modify configuration. The action of the configuration tree in tree group 38. The configuration tree group 38 contains a complex configuration tree T1~Tm, where m is a positive integer greater than one. For example, configuration tree group 38 includes configuration tree 11d in FIG. Device files are used in Unix, Linux, etc., and similar operating systems. 9 201007475 • To represent specific device drivers and their corresponding executables, for example, stored in /dev, allowing applications to pass standard output/input System Call • To interact with the driver represented by the device profile. In the present embodiment, the file name of the file 36 is set to "xmlconf" and the device file 36 is associated with the device file 36 to configure the tree in the plural. In FIG. 4, the device main code (maj〇r number) N1 in the device slot 36 is a number representing the driver 34, and the device minor code N2 contains the complex number representing the configuration tree T1~Tm. Each device code represents a configuration beta tree. The application in application group 1, the function or driver 34 in application interface 30 can be configured to read and modify a particular configuration tree in configuration tree group 38 through device file 36. The application can open the device file /dev/xmlconf to find the device main code N1, and the device number can be requested to find and utilize the driver 34 through the device number. The driver 34 can find a corresponding specific configuration tree by using a device code, and modify the configuration tree or read and return the configuration parameter value to the application according to the request of the application. Examples of device broadcasts include character special files or character devices and block special files or Mock devices. The character device corresponding to the character device file and the operating system exchange data with the character as the soap level, and the block device and the operating system exchange data in units of larger data blocks. Examples of character devices include modems and telephone communication related devices. Examples of block devices include hard disk drives and optical disk drives. The driver 34 reads the configuration parameter values of one node on the configuration tree each time, so the device file 36 can be a character device file. 201007475 Example: Figure 5 shows an example of a configuration parameter file 12 with a portion of the corresponding configuration tree shown in Figure 6. Configuration parameter file 12a, where the configuration parameter package is included between <ConfigTree> and </ConfigTree>. <AtmCfg> includes a setting related to an asynchronous transfer mode (abbreviated as ATM) in the middle of </AtmCfg>. <AtmCfgTd> and </AtmCfgTd> contain settings regarding the ATM connection type (Link Type), such as "CBR" means to connect at a constant rate. <AtmCfgVcc> and ❹</AtmCfgVcc> mainly include a persistent virtual circuit (PVC) parameter of the ATM layer. <86 (^£吕> and </SecCfg> mainly include settings related to network security. There is a Wi_Fi (IEEE 802.11) related setting. <11〇1^匸£8><; /RouteCfg> Between the main setting of the static routing table of the electronic system 200. The main thing is to do the corresponding (Port Map) settings.

The configuration parameters between <wan_8_35> and </wan_8_35> are mainly used to establish a wide area network (Wide Area Network) , referred to as WAN) interface, it is closely related to ATM PVC. 11 201007475 The kernel program 13 or application in the electronic system 200 can start the conversion of the configuration parameter file 12a into the configuration tree. For example The kernel program 13 initiates the establishment of the configuration tree when the electronic system 2 is powered on. Alternatively, the application of private Al (where i is a positive integer, and lSi^n) initiates the establishment of the configuration tree. The kernel program 13 executed in the electronic system 200 Or the application programs A1 to An can use the application interface 30 to convert the configuration parameter file 12a into a specific data format' and then hand it to the driver 34 to establish a corresponding configuration tree of the configuration parameter file 12a. § See Figure 7, when the electronic system When the program in 200 needs to establish a configuration tree, the function used to create the configuration tree in the application interface 30 (step 7〇〇) is the name of the device file 36 corresponding to the driver 34 in the above request. The above function responds to the request of the above program to analyze the configuration parameter file 12a to generate a guest structure representing the structure of the configuration parameter file 12a and its configuration parameter values (step 702). The value of the autoScan attribute in the <protocol:^ sign can be The data structure of step 702 is represented by "pr〇t〇c〇l.autoScan=enable". The above function is further transmitted through the system call 32 of the operating system of the electronic system 200. The slot name of the device slot 36, the above data structure and other data are transferred to the kernel program 13 (step 704). The kernel program 13 obtains the device main code N1' in the device file 36 based on the above file name, and then obtains the driver 34 according to the device main code N1, and passes the data structure to the driver 34, so that the driver 34 starts to establish the above data structure correspondingly. The configuration tree (step 706). The driver 34 adds the device minor code N2 as the code of the configuration tree to be established (step 708), and according to the above data structure, establishes the configuration tree Tj corresponding to the configuration parameter file 12a (where j is a positive integer, and step 12 201007475 - Step 710). Fig. 6 shows a schematic diagram of the conversion of the block B1 in the configuration parameter file 12a into a configuration tree. In the block B1, the <SystemInfo> and the </SystemInfo > tags are named "SystemInfo," and include the tags named "protocol", "sysLog", and "sysUserName". Therefore, the program is in the program. In the case of the request, the driver 34 establishes "nodes corresponding to "SystemInfo", "protocol", "sysLog", and "sysUserName" in the configuration tree corresponding to the configuration parameter file 12a, and "SystemInfo" is "protocol", "sysLog" And the parent node of the node such as "sysUserName". The "protocol" tag contains the attributes "autoScan", "upnp", "igmpSnp", "igmpMode", macFilterPolicy", "encodePassword", and "enetwan" correspondingly. Program 34 will create nodes such as "autoScan,", "upnp", "igmpSnp", "igmpMode", "macFilterPolicy", "encodePassword", and "enetwan" as child nodes of the "protoc〇i" node, and each attribute corresponds to The node contains its attribute values. Similarly, driver 34 will also create 'sysLog' and "sysUserName". The child nodes of the node, and the other nodes of the above configuration tree. After the configuration tree Tj is established, the other program can read or modify the configuration parameter values in the node of the configuration tree Tj. Referring to FIG. 8, when the electronic system 200 is inside When the program needs to modify a specific node in the configuration tree (hereinafter referred to as a target node), it requests to execute a function for modifying the configuration tree in the application interface (step 800), wherein the request includes the corresponding driver 34. The name of the device file 36, the new configuration parameter value, and other data. For example, a program that executes a PPP program or a Dynamic Host Configuration Protocol (Dynamic Host 13 201007475 • Configuration Protocol, DHCP for short) obtains the electronic system 200 from the WAN. The new IP address is used as the new configuration parameter value, and then the IP address of the target node in the configuration tree Tj for recording the IP address of the electronic system 200 is updated. The application can specify in the above request in step 800. a name of the target node and a path from the configuration tree Tj to the target node, wherein the path includes a parent node of the target node And the name of the ancestor node. The above function responds to the request of the program, and transmits the file name, the target node name, and the new configuration parameter value in the request to the kernel program 13 through the system call of the operating system of the electronic system 200 (step 802). The kernel program 13 obtains the device main code N1 in the device file 36 according to the above file name, and then obtains the driver 34 according to the device main code N1, and passes the new configuration parameter value to the driver 34, so that the driver 34 updates the configuration tree. The configuration parameter value within the target node in Tj (step 804). The driver 34 retrieves the target node in the configuration tree Tj (step 806) and updates the configuration parameter value in the target node with the new configuration parameter value (step 808). In step 806, the driver © program 34 may obtain the target node according to the path of the target node or search for the configuration tree Tj for acquisition. In the example of the configuration tree Tj in FIG. 6, the IP address of the electronic system 200 is from the "6 1 1 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , After the IP address is updated, the firewall program in the electronic system 200 can read the IP address of the electronic system 200 from the configuration tree Tj and perform its task according to the new IP address in the node. The network address translation (NAT) program of the system 200 performs NAT according to the new IP address in the above node. 14 When the specific r: program in 201007475 needs to read the configuration tree, called the target node) The request execution function ((4) 9〇〇) for the configuration tree in the application medium, wherein the request includes: the name of the device file 36 of the program 34 and the name of the target node 2: the program can be used in step 900 The above request indicates the path from the configuration tree node, and the path includes the name of the parent node and the ancestor point of the target node.
