Description

Internationalized Internet Address Processing System and Method

The present invention relates to a system and method for processing an Internet address, and more particularly, to determine a language of an input character by using a method such as determining a language code of a character input by a user in processing an internet address written in multiple languages. By using a multilingual address processing system installed in a network, the present invention relates to a system and a method for enabling processing even if a country separator is inputted in a keyword form without separately inputting or adding a country separator.

Just as phone numbers are necessary for phone calls, Internet addresses are essential to accessing information on the Internet. For example, in order to deliver or receive a letter (information), you need to fill out the address of the other party. For this purpose, the Internet address is said to be one of the most basic and most important factors in the construction of the Internet.

In the early days of the Internet, only a few computers were connected by a network, so there was only an IP address, a machine-centric address, used to identify each device connected to the Internet. An IP address is the most basic Internet address that identifies the computer or device connected to the network in the Internet space. It is a tool for finding each computer or device on the Internet. All computers or devices connected to the Internet must be IP. You must have an address. IP address is necessary for the use of the Internet, but it is composed of numbers. Especially, in case of IPv6, it is expressed as long hexadecimal number, so it is difficult for a person to remember and use it. Domain Names have been developed.

Domain names are organized in a hierarchical structure, called an Inverted Tree, with a tree placed upside down under a domain name called “.” Or Root. The steps immediately below the root domain name are called Level 1 or Top Level Domains (TLDs), which are known as com, net, org, edu, etc. and countries such as kr, jp, and cn. It is divided into a top level domain (ccTLD, country code TLD). The level below the TLD is called the Second Level or Second Level Domain (SLD) and is used below the national top level domain to characterize the institution.

The domain name, together with the World Wide Web, has made a significant contribution to the explosive growth of users by making it easier to use the Internet, and is still the most widely used method for accessing information on the Internet. These domain names are available only for English letters called LDH (Letter, Digit, Hyphen), but the characters of Korean, Japanese, etc. are converted into LDH codes according to the prescribed rules according to the internet address request in the native language of non-English speaking countries. This has led to the introduction of Internationalized Domain Names (IDNs), which allow the use of domain names in their own language.

In order to process multilingual domain names composed of native languages of non-English speaking countries, IDN uses a coding conversion method that converts non-English characters into English characters according to a predetermined rule. For example, the non-English letter 'Korea' is changed to 'xn-3e0bs9hfvinn1a'. However, since the multilingual domain name uses the hierarchical structure of the existing domain name, it is inconvenient to add a TLD such as a country code after the company name, the brand name, etc. of the website. Moreover, TLDs often do not have much meaning besides distinguishing each treatment system.

The present invention provides a method for automatically attaching and processing a TLD by judging an input language even if a user inputs a TLD that must be input and attached when using a hierarchical multilingual domain. It is about. However, the existing methods are inconvenient to install a separate program in the user terminal or domain name server for this process.

In the present invention, the language and country information of the user is determined using a method such as determining a language code of a character input by a user in processing an internet address displayed in multiple languages, even if a country separator is not separately inputted or added. Use the method to make it possible to process in.

The present invention utilizes a method of processing a code conversion and language code determination in a network terminal to which a user terminal is connected without separately installing a program of a corresponding function in a user terminal or a domain name server in order to process an internet address displayed in multiple languages.

In the multilingual address processing system and method according to the present invention, even when only a word in the form of a keyword is inputted without using a separate TLD, the TLD is automatically attached to determine the input language to facilitate the use of the Internet. It is effective. In addition, since there is no need to install a separate program in the user terminal or domain name server for processing, it is possible to provide a service to a plurality of users without inconvenience to the user.

The present invention relates to a multilingual Internet address processing system and method, and more particularly, to a system and method for automatically attaching and processing a corresponding TLD by determining information such as an input language even when an Internet address is input in a keyword form. For example, even if you input only 'Korea' in Korean, you can add '.kr' or '.Korea', which corresponds to Korea, after the input string 'Korean,' followed by 'Korean.kr' or ' Korea, Korea. '

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the technical idea of the present invention.

1 is an overall configuration diagram of a system for multilingual address processing according to an embodiment of the present invention.

The system for multilingual Internet address processing according to the present invention includes a multilingual address processing system 200, a domain name server 300, and a web server 400 finally connected to a user terminal 100 and a multilingual internet address processing function. ) To function.

The user terminal 100 is a device where a browser is installed and a user inputs and uses an Internet address to access a web site. The user terminal 100 can be any device capable of internet, such as a refrigerator, a TV, a smartphone, as well as a general PC. It is not particular about connection method such as mobile.

The multilingual address processing system 200 serves as a core function for processing a multilingual internet address according to the present invention, which is located at the interruption of a network where the user terminal is connected to the Internet, and the router used by the user terminal to connect to an external network. It can be located between the Internet service providers, and can be located in the Internet service provider to which the user terminal is connected, and receives and processes the data transmitted through the network such as routers and hubs where data transmission is concentrated through the Internet. The place where the purpose can be achieved is not particularly limited.

The domain name server 300 is a server that responds to an IP address in response to a domain name query. Even if the general Internet users do not know the numerical IP address, it is easy to use a domain such as www.kipo.go.kr. Makes it easy to use the Internet. The domain name has a hierarchical structure, and the domain name server 300 finds a corresponding IP address through a process of sequentially checking from a high level in order to interpret and process a queried domain name. However, the domain name server 300 is made to process only English characters composed of ASCII at the time the domain name system was designed, so when querying with a conventional domain name server 300 should be in the form of characters consisting of ASCII.

Web server 400 is a server that contains the content of the Web site that the user finally wants to access using the Internet address. The user terminal 100 receives the IP address of the web server 400 from the domain name server 300 to connect to the server.

Hereinafter, the multilingual address processing system 200 performing core functions for performing a function according to an object of the present invention will be described in more detail.

The multilingual address processing system 200 passes all network communication data transmitted from the user terminal 100, and selectively takes action on an object requiring processing. There are two methods of receiving and processing network data by the multilingual address processing system 200 located in the middle of a network, such as a mirroring method and a proxy method.

The mirroring method is a method of copying and processing the transmitted data by using network devices such as an L7 switch or a network tap. Even if a failure occurs in the multilingual address processing system 200 located in the middle of the network, the connection and use of the network may be disrupted. There is an advantage that does not give.

The proxy method adds a proxy device in the middle of the network and allows all data to pass to the next step only after passing through the proxy server. The processing can be passed to the next step only when the proxy device is completed. There is this.

However, processing the entire network data that is transmitted in both the mirroring method and the proxy method is time consuming and requires a lot of load on the system. Therefore, it is difficult to extract only the data that is to be processed and to process it quickly. desirable.

Data for network communication is made of communication data called an Ethernet frame to be transmitted, and various information necessary for communication are included as header information in the Ethernet frame.

2 is a structure of Ethernet frame which is communication data used in the Internet.

Among the contents of the Ethernet frame, the Ethernet header contains information such as the MAC address, which is a hardware address, and the IP header contains information about the source and destination IP addresses. The TCP (UDP) header includes information on a communication port of a service.

The multilingual address processing method according to the present invention only needs to process the data of the domain name server 200 as a destination among the data transmitted through the network, and for this, for the network data transmitted through the mirroring method or the proxy method, By checking the service communication port information of the TCP header, it is possible to determine whether the target.

In the case of a general HTTP query, the destination port number is 80 and the domain name query that is queried by the domain name server 200 is differently used as the destination port number is 53. Therefore, the target port number is processed by checking the port number of the destination. It is possible to determine whether or not, and the process according to the present invention is carried out only when it becomes a process target.

The domain name query data that is transmitted by the multilingual address processing system 200 by a proxy or mirroring method and determined to be a processing target through port number checking or the like has a structure as shown in FIG. 3.

The multilingual address processing system 200 checks whether the Internet address queried for the content of the query field among the contents of the domain name query data is a keyword type, and if it is determined that the queried Internet address is a keyword type, character code check etc. Determines the language of the text entered through. In this case, the multilingual address processing system 200 may have different processing procedures depending on whether the contents of the query field of the domain name query data transmitted from the user terminal 100 are in English, that is, 7 bits or 8 bits. Can be.

In most cases, when a non-English alphabetic language address is input, the browser of the user terminal 100 is encoded in 7-bit English form such as Punicode, and then transferred to the domain name server 300. Coding query messages can be easily distinguished, such as 'xn--' in the case of Punicode, and are easy to determine. However, an English-language query message cannot determine which character the user has entered by itself. Therefore, in this case, the query message encoded in the English form is converted back to determine the type of the character. In many cases including the Punicode, the reverse conversion is converted to the Unicode form. Unicode is a standard code designed to consistently represent and handle all the characters of the world on a computer. Existing encodings are limited in size and scope, and are incompatible with each other in multilingual environments. Work is underway with the goal of replacing all the different character encoding methods with Unicode. The character input to the user terminal 100 may determine the type of the corresponding language by checking and analyzing the character set of the input character in the Unicode state. A character set refers to a collection of all characters for expressing a language used in a single language, and all special characters such as a sign and a space are also included in the character set. When the input character is identified in which language, the multilingual address processing system 200 attaches the TLD corresponding to the input language after the query message in the form of a keyword. For example, if the input language is determined to be Korean, '.kr' or '.Korea' is attached. If the input language is determined to be Japanese, '.jp' or '. 日本' is attached. The attached TLD may be an existing ccTLD, but may be another TLD separately designated, or may be expressed in multiple languages. In this case, the information about the TLD may exist as a DB in the multilingual address processing system 200 or may be stored in a separate server externally, and may be used by receiving contents from an external server and storing the information in the multilingual address processing system 200. Can be. The multilingual address processing system 200 adds a TLD to a multilingual input in the form of a keyword, encodes it in a 7-bit form that the domain name server 300 can process, and then delivers the TLD to the domain name server 300, thereby providing a domain name server ( 300 to find the IP address corresponding to the response to the user terminal 100. In this case, the 7-bit TLD of the 7-bit query message received from the user terminal 100 is simply added to the domain name server 300, or the 7-bit query message is converted to the 8-bit Unicode form TLD in the state In addition, the encoding order of the query message and the TLD, such as a 7-bit encoding method, may be implemented in various forms, and is not limited to any one method.

On the other hand, when the content of the query field of the domain name query data transmitted from the user terminal 100 is 8 bits, it is difficult to confirm in which language the character entered by the user is in a language. In order to confirm this, the multilingual address processing system 200 assumes a query message as a specific encoding, and determines the encoding and the language type of a character input by the user by checking whether the conversion is normally performed after conversion to Unicode. At this time, since there are various encoding methods and it may be a problem in system load and processing time to convert and check each method individually, the multilingual address processing system 200 has a high utilization rate based on the location information of the user terminal 100 and the like. It is desirable to check the language type of the input character by applying the encoding first. The query message in which the input language is determined is encoded in a 7-bit form that can be processed by the conventional domain name server 300 after the TLD corresponding to the language is added, and then transmitted to the domain name server 300, thereby providing a domain name server 300. The corresponding IP address can be found and responded to the user terminal 100.

4 is a flowchart illustrating a multilingual address processing method according to an embodiment of the present invention.

When the user inputs the Internet address to the browser address bar of the user terminal 100 (S101), the input Internet address is queried to the domain name server 300 (S103). The data queried by the domain name server 300 first passes through the multilingual address processing system 200 located in the middle of the network (S105), and the multilingual address processing system 200 receives the domain name server 300 for the received data. It is determined whether the data is queried () (S107). If the network data is not a domain name query, the multilingual address processing system 200 terminates the processing, and the network data is continuously processed according to a normal data transmission method. If the multilingual address processing system 200 receives the domain name query in the middle of the network, the multilingual address processing system 200 checks the query message part of the contents of the query data to determine whether the query message is a keyword type. (S109). The keyword can be determined by checking whether the '.' Is included in the query message of the domain name query data query field. If it is determined in step S109 that the query message is not a keyword type, the multilingual address processing system 200 does not function any more, and network data is transmitted according to a normal data transmission method and is a domain name. The server 300 processes the query message (S115). If it is determined that the query message is in the form of a keyword, the multilingual address processing system 200 checks the language type of the Internet address input by the user through analysis of the query message (S111). When the query message of the domain name query data query field transmitted from the user terminal 100 is converted to 7-bit punycode or the like, the national language address processing system 200 inversely converts the query message back to Unicode, and converts the character set. You can check the language of the input text. However, if the query message of the domain name query data query field transmitted from the user terminal 100 is 8 bits, the encoding and language type of the character input by the user are checked by converting the query message to Unicode and confirming whether it is converted normally. Can be. Since there are many encoding methods, it may be a problem in system load and processing time to convert and check each method individually. Therefore, it is preferable to check and apply the encoding having high utilization rate based on the location information of the user terminal 100. . The multilingual address processing system 200 adds a TLD corresponding to the language to the query message in which the input language is determined (S113), and then encodes the multilingual address processing system into a 7-bit form that can be processed by the conventional domain name server 300. By forwarding (S115), the domain name server 300 finds an IP address corresponding to the domain name server 300 and responds to the user terminal 100.

Thereafter, the user terminal 100 receives the IP address of the web server 400 corresponding to the Internet address input from the domain name server 300 to access the web server 400.
