Description

TECHNICAL FIELD [0001] The present invention relates to a method and apparatus for shortening a connection time of a web site,

The present invention relates to a method for shortening a connection time of a web site of a terminal, and more particularly, to a method of shortening a connection time of a web site of a terminal accessing a website through a DNS query and a DNS information collection server .

A large number of computers are connected on the Internet, and each computer has a specific address.

In a network based on TCP / IP (Transmission Control Protocol / Internet Protocol), an address for referring to each of these computers is called an IP address.

For this reason, it is easy to create a memorable alphabetical name and use it instead of an IP address, which is the Domain Name.

Briefly explaining a process of a terminal accessing a server in a network, when a user inputs a domain name and requests a connection, the terminal transmits a DNS query to a DNS (Domain Name System) server.

The DNS server stores information on an IP address matched with a domain name and each domain name, searches for an IP address corresponding to the received domain name, and provides the retrieved IP address information to the terminal.

The terminal receives the IP address information from the DNS server, and uses the IP address information to access the server of the desired web site.

When a terminal accesses a web site, it must secure the IP addresses of various section pages included in the main page and the main page of the web site.

For example, a server for building a website is constructed as a separate server for functions such as photo, advertisement, and mail. When a first terminal accesses a corresponding website through a domain name, Information from multiple section pages should be retrieved from the respective server.

In this case, the main page and each section page are generally defined as the content of a separate host name. In order for the entire page of the website to be displayed, in addition to the DNS query for the host name of the main page, DNS queries are made.

For example, when a user accesses a website having a domain name of xxx.com, the IP address of the host name www.xxx.com of the main page and the IP address of the host page news.xxx.com of the section page You need to go through a DNS query.

Since the DNS query process is performed several times, it takes a considerable time for the user to input the domain name and access the website.

In order to access a specific website without a DNS query from the viewpoint of the terminal, there is a method of storing the host name and the IP address corresponding to the host name in the hosts file.

However, it is not possible to store the IP address in the fixed hosts file if the IP address of the section page constituting the main page has to be acquired and the configuration of the section page changes from time to time, such as a portal site. It should be used only if it is necessary to set the IP address for the URL fixedly.

In order to solve the above problems, it is an object of the present invention to provide a method for shortening a connection time of a web site that can minimize a time required for a DNS query when a host name is input in a terminal and is connected to a server of a web site, And a DNS information collection server and a terminal.

1 is a block diagram of a network system according to an embodiment of the present invention.

As shown in the figure, the network system according to an embodiment of the present invention includes a terminal 100, a DNS information collection server 200, a DNS server 300, and a website server 400, (Internet Protocol) based packet network.

The terminal 100 may be implemented as a known mobile communication terminal 100 capable of performing IP-based data communication through a mobile communication network such as a smart phone, a tablet PC, and a PDA, or may be implemented as a conventional desktop PC, a laptop PC, and can connect to each of the web site servers 400a, 400b, and 400c through a packet network.

The terminal 100 may include a communication unit 110, a storage unit 120, and a control unit 130, and detailed features thereof will be described later in detail with reference to FIG.

The DNS server 300 searches the domain name system for an IP address corresponding to a domain name or a host name according to a request from a client and provides the IP address to a client.

An IP address represented by a set of four numbers in the range of 8 bits is used as an identifier of each client and a server on a TCP / IP-based network. In order to facilitate access to a specific server by users of the terminal 100, It is possible to use a domain name represented by a character other than the IP address to be represented.

In general, when the terminal 100 intends to access the website server 400 through a host name, the DNS server 300 requests the DNS server 300 to query the DNS server 300, and the DNS server 300 obtains the IP address corresponding to the host name Information is retrieved from the stored database and transmitted to the terminal 100.

In this specification, the DNS server 300 is represented as one server. However, the DNS server 300 may include a server of a mobile communication company to which the terminal subscribes, a server that manages an identifier (for example, .com) of a domain name, And a server managing the host name of the DNS server 300. One DNS server 300 can directly request a DNS query to another DNS server 300 if the information stored in the DNS query result does not exist have.

Here, the domain name is an identifier of a representative server operating the web site server 400, and can be expressed as 'xxx.com', and the host name can be represented by an individual server managing individual services provided by the corresponding web site As an identifier, it can be expressed as 'news.xxx.com', 'img.xxx.com', and the like.

The DNS information collection server 200 connects to the DNS server 300 at predetermined time intervals and performs a DNS query for at least one host name set in advance.

At this time, information on at least one website having a high access frequency is analyzed by the terminal 100, and a DNS query can be performed on a host name of at least one website having a high access frequency.

That is, it is possible to confirm a Web site frequently accessed by a large number of users other than a specific terminal 100, select a top ten web sites among them, and perform a DNS query in advance. May be independently performed by the DNS information collection server 200 irrespective of the request to the DNS server 300. [

The DNS information collection server 200 may receive information of a website frequently accessed by users from DPI (Deep Packet Inspection) equipment provided by a network operator to adjust traffic on the network.

On the other hand, the DNS information collection server 200 can secure an IP address for a plurality of section pages included in a main page as well as a main page when initially accessing a web site having a specific host name.

In the case of the server providing the web site, when the terminal 100 enters the initial host name and accesses it, it sets the index.html file to be read and transmits data about the main page to the terminal 100.

At this time, the main page may include a plurality of section pages, and the web site server 400 may include a server for managing the main page and individual servers for providing information such as news, images, and advertisements , It is necessary to fetch information from each individual server in order to display the whole page, and when the connection to the individual server fails, the contents of the corresponding section page can not be displayed.

At this time, each individual server is identified by a separate host name, and there may be an IP address corresponding to each host name.

For example, referring to FIG. 2, there are three section pages 12, 14, 16 in the main page 10 of a particular web site, including news, images, , The host name of the server managing each section page will be named 'news.xxx.com', 'img.xxx.com', and 'ad.xxx.com', respectively. .

In addition, the IP address of the main page may be determined as 'a.b.c.d', and the IP addresses of each section page may be determined as 'a.b.c.x', 'a.b.c.y', and 'a.b.c.z'.

Here, a, b, c, x, y, and z may be provided as an integer from 0 to 255. [

The DNS information collection server 200 requests the DNS server 300 to perform a DNS query and obtains the IP address 'abcd' of the main page and the IP addresses 'abcx', 'abcy', 'abcz' Can be obtained.

Meanwhile, the predetermined time interval at which the DNS information collection server 200 periodically performs the DNS query for at least one host name may be determined according to the TTL value of each IP address.

In general, the TTL (Time To Live) value indicates the validity time of the packet data included in the packet header, and the IP header indicates the maximum allowable number of hops before the packet is discarded.

The IP address information transmitted from the DNS server 300 includes a TTL value in seconds, which is the effective use time of the corresponding IP address information. If the TTL is exceeded, even if the web site is accessed through the corresponding IP address, There is a case that can not be done.

For example, when DNS queries are performed for three Web sites A, B, and C among high-frequency Web sites, the TTL of each IP address may be set to 300 seconds, 500 seconds, 1000 seconds, and IP If 300 seconds have elapsed after the address is secured, it may happen that the web site A can not be connected.

Therefore, the DNS information collection server 200 can perform a DNS query on the Web sites A, B, and C in units of a minimum of 300 seconds.

The DNS information collection server 200 can generate and store an IP address list including at least one IP address information obtained as a result of the DNS query and transmit the IP address list to each terminal 100 in the network.

The DNS information collection server 200 may include a DNS acquisition unit 210, a list storage unit 220, and an information transmission unit 230. The functions performed by the DNS information collection server 200 will be described in detail with reference to FIG. .

Upon receiving the IP address list, the terminal 100 can generate a host file based on the received IP address list or update the previously stored hosts file.

The Hosts file is composed of a text file including IP address information corresponding to the host name and the host name. When the terminal 100 accesses the web site through the host name, the host file is referred to first.

When the terminal 100 generates or updates the hosts file using the IP address list received from the DNS information collection server 200 and then the terminal 100 attempts to access the corresponding website, You can access the website using the IP address stored in the hosts file.

When the IP address corresponding to the host name input by the user of the terminal 100 is not stored in the hosts file, the terminal 100 checks whether the corresponding IP address is stored in the cache memory, The DNS server 300 requests a DNS query for obtaining an IP address corresponding to the host name.

As described above, the DNS information collection server 200 collects the IP address information of a web site having a high access frequency by a normal user and transmits the IP address information to the terminal 100, so that the terminal 100 accesses the web site In many cases, even if the IP address information of all the Web sites is not stored in the hosts file, the time required for DNS queries when accessing the Web site may be reduced.
