Description

Web-Based Management Method Of Network Device Be Different In Version}

The present invention relates to a web-based management method of a network device having a different version, and in particular, it is different for each version of the network device that is dynamically changing to a specific location in a web document transmitted from a web browser for web-based management of the network device It's about web-based management of different versions of a network device that can represent the content or image that should output the results.

In general, an interworking structure of a network device using a web-based management (Web-Based Management) method is shown in FIG. 1, a local area network (LAN), a wide area network (WAN), or the Internet. It is connected to operator terminal using commercial web browser (Web-Browser) and HyperText Transfer Protocol (HTTP) protocol, and web server using CGI (Common Gateway Interface) method for efficient management of the network equipment. To perform remote management and maintenance of network equipment.

In addition, SSI (Server Slide Include) technique is used for remote management and maintenance. The SSI technique refers to a function that a web server includes a document requested from a web browser, and is used on the World Wide Web. An HTML (HyperText Markup Language) document, which is a language for describing hypertext, or an execution result value of a predetermined program or an environment variable value related to SSI may be included.

In other words, the contents repeatedly used throughout the web document (e.g., the e-mail address of the web master) are prepared as one independent document, and the contents are included in a predetermined position of the web document in need thereof. In order to use the technique, the web server must find an SSI statement included in an HTML document, which is a web document, and include an independent document at the statement position. Therefore, a load on the web server to find the SSI statement occurs.

Therefore, in the related art, in order to reduce the load of the corresponding web server, by defining the extension of the HTML document including the SSI command as 'shtml', only the document having the corresponding extension 'shtml' was able to find the SSI command and include the independent document. .

In this case, the types of SSI commands include a 'config' command for setting a specific variable value such as a date format, a file display format, an error message, an 'include' command for including a specific web document in a corresponding location, 'Echo' command to print out environment variable values related to SSI, 'fsize' and 'flastmod' command to search file size or last modified date, and run Common Gateway Interface (CGI) or Unix program. There is an 'exec' command for outputting the result, which is described in Table 1 below.

command tag Explanation config errmsg Specifies what message the web server will return to the browser when an error occurs while parsing the document. timefmt Specify a new presentation when the web server sends the date and time. sizefmt A format specification that determines the size of a file. include virtual Include a new document in the current document. (HTML document) file echo var Output of environment variable values related to SSI. fsize virtual Print the size of the file. file flastmod virtual Print the last modified date of the file. file exec cmd Run the program using the shell and print the result. cgi Run the CGI program in the directory specified on the web server and print the result.

On the other hand, the web server included in the above-described network equipment performs the information exchange and command by interworking with the web browser in a CGI method based on the HTTP protocol, but based on the HTML comments specified in SGML (Standard Generalized Markup Language) SSI technique Do this.

Here, the HTML comment begins with '<!-' And ends with '->', starting with the SSI statement with '<!-#' By adding '#' to the beginning of this general HTML comment. And then write an SSI statement in the form '<!-# Command tag 1 = "value 1" [tag 1 = "value 1"] [tag 2 = "value 2"]->'.

When the SSI statement included in the web document is expanded by the web server, the operator recognizes the HTML page as one HTML page. For example, when the SSI statement includes the 'include' command, the accompanying drawing is attached. It is expanded as shown in FIG.

In other words, two web documents consisting of a 'main.html' file and a 'signature.html' file are displayed as one 'main.html' extension on the operator terminal, and the 'signature.html' file is By reusing, you don't have to re-enter the repetitive contents. If you need to modify the web document, you only need to modify the contents of the 'signature.html' file without having to modify the entire web document.

However, in the related art, dynamic data cannot be described when the versions of network devices using the web-based management method are different. Therefore, a separate web document should be created and stored in the memory according to the corresponding version. In order to output different results depending on the version, a separate web document and program work were required.

In addition, only the HTML document can be included in the web document, but the image file cannot be included, so that the image of the appearance of the network device may not be dynamically displayed in the web browser.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to include a specific string in a web document and transmit it to a web server for web-based management of a network device, and the specific string included in the web document in the web server When detected, the corresponding function is called and executed to express different result values or images according to the version of the network device, thereby enabling efficient management of the network devices having different versions.

Another object of the present invention is to save the memory of the network device by storing only different images for each version without the need to create a separate web document for each version of the network device and store it in the memory.

Features of the present invention for solving the object as described above, the process of transmitting a web document containing a specific character string to the network device for the management of the network devices of different versions; Parsing a string included in a web document by character and checking a version of a network device when a specific string is detected, and calling and executing a corresponding CGI function; It includes the process of outputting different results or images on the web browser according to the version of the network equipment.

The specific character string may be resident in the nonvolatile internal memory of the network device to detect the specific character string included in the web document.

In addition, the process of outputting different result values or images according to the version of the network device on the web browser, in the case of different result values according to the version of the network device is transmitted to include in a specific character string position of the web document And outputting the image on the web browser, wherein the image is linked to a specific character string position of the web document and transmitted to the web browser in the case of different images according to the version of the network device; And receiving the linked image from the network device and outputting the linked image on a web browser.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, for the web-based management of the same network equipment with different versions, it is possible to express content that is dynamically changed to a specific location in a web document transmitted from a web browser, that is, a content or an image that should output different results for each version of the network equipment. This is applied by applying the SSI technique, inserting a specific string corresponding to the modified SSI instruction in the web document and sending it to the web server of the network device, and the web server calls and executes a function corresponding to the inserted specific string. After that, the corresponding result value or image according to the version of the network device is included in the original web document and transmitted to the web browser, so that the result value or image for each version of the network device is output on the web browser.

On the other hand, the schematic structure for web-based management of different versions of the network equipment according to the present invention is as shown in Figure 3 attached, between the web browser 30 and the network equipment 40 used by the operator By exchanging web documents in a CGI manner based on the HTTP protocol, dynamic data and image representation corresponding to the version of the network device 40 is possible.

Here, the network device 40 includes a web server 41 that interworks with the web browser 30 and a CGI execution unit 42 that performs a corresponding CGI program in association with the web server 41, The web server 41 receives a web document including a specific string requested in a 'GET' or 'POST' method from the web browser 30, and then links the web with the CGI execution unit 42. If a specific character string included in the document is detected, the version of the network device 40 is examined, and the appearance image of the different network device is linked to the web document according to the version, or different result values are included in the web document. Transmission to the web browser 30 side.

In this case, the 'GET' means that each item is delivered in a form appended to the Uniform Resource Locator (URL), and the corresponding 'POST' means that each item is delivered in a message form.

In the present invention having such a structure, the web-based management operation of the network equipment having different versions will be described in detail with reference to FIG. 4.

First, when the web browser 30 transmits a web document including a specific string requesting predetermined information for management of a specific network device to the network device 40 in a 'GET' or 'POST' manner (step S41), The web server 41 of the network device 40 parses the character string included in the web document transmitted from the web browser 30 character by character (step S42), and differs according to the version of the network device 40. It is checked whether a specific character string for representing a result value or an image is detected (step S43).

At this time, when the specific string included in the web document is not detected, the web server 41 returns to step S42 to parse the next string by one character, and when the specific string included in the web document is detected, The web server 41 checks the version of the network device 40, calls and executes the corresponding CGI function in association with the CGI execution unit 42 (step S44), and then checks the version of the network device 40. As a result, different result values are included in a specific string position of the web document, or an image corresponding to the version is linked to a specific string position of the web document (step S45).

Thereafter, the web server 41 transmits a web document including different result values or linked images to the web browser 30 according to the version of the network device 40 (step S46).

Accordingly, the web browser 30 outputs the transmitted web document when the web document transmitted from the web server 41 includes different result values according to the version of the network device 40. If the image corresponding to the version of the network device 40 is linked to the web document transmitted from the server 41, the linked image is received and output through the web server 41 of the network device 40 (step S47). This enables dynamic data representation.

For example, as shown in FIG. 5 attached to a web browser, when a web document in HTML format having a specific string of '$ SR_VERSION ()' is created and transmitted to a network device for managing different versions of the network device, The web server of the network device searches the transmitted documents in order, checks the version of the network device if a specific string ($ SR_VERSION ()) is detected, and executes a CGI function to link different images according to the version. In this case, the image refers to an object image (xxx. Jpg) that is prepared in advance for each version of the network device and stored in the nonvolatile internal memory (not shown) of the network device.

The object image linked to the web document is represented as dynamic data at a specific position of the static web document through an internal processing form as shown in FIG. 6.

Meanwhile, in order to detect a specific string ($ SR_VERSION ()) included in a web document in a web server of the corresponding network device, the specific string ($ SR_VERSION ()) must be resident in internal memory, and the specific string ($ SR_VERSION Only one ()) should be included in a single web document.

In addition, the embodiments according to the present invention are not limited to the above-described embodiments, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.

As described above, the present invention includes a specific string included in a web document and transmitted to a web server for web-based management of the network equipment, and when a specific string included in the web document is detected by the web server, calling and executing a corresponding function. Therefore, different result values or images can be expressed according to the version of the network device, thereby enabling efficient management of the network devices having different versions.

In addition, the present invention can save the memory of the network device by storing only the different image for each version without the need to create a separate web document for each version of the network device to store in the memory.
