Description

A system for achieving internet business based on regional basis by a local server and method therefor}

The present invention relates to an internet business, and more particularly, to a solution and a method for implementing a local business based on a local server by a local server for implementing a new internet business through an economical high speed internet network based on a local network.

The existing internet business can be divided into two categories: contents business for exchanging information, and infrastructure for facilitating such content business. The content business is expected to continue to be invested in the Internet business field, and the Internet-based business should be closely watched depending on the business environment as to how much investment will be made in the future because the current investment and its profit realization are unclear. It is predicted.

Regarding the Internet-based business, the Internet-based business is currently being carried out by a low efficiency centralized sales method to establish a high-speed communication infrastructure (base) at the national level. For example, Internet-based operators include Korea Telecom and Hanaro Telecom, which are building a high-speed communications infrastructure in a centralized, centralized business mode using the Asymmetric Digital Subscriber Line (ADSL) method. These operators are building a high-speed communications infrastructure by using a centralized domain method, which has a large server computer in the center and connects many users nationwide.

However, existing service providers who are building a high-speed communication infrastructure by a centralized sales method are unable to properly install the facilities to users who want to join them at the time they want (the lack of IP and the rapid development of high-speed communication networks). Due to the large number of consumer waits), the existing communication infrastructure cannot guarantee the speed and duplex desired by the subscriber. In addition, content providers that use a centralized, high-speed communications infrastructure must have large servers in the center and connect with a large number of subscribers across the country, so that even with the initial capital investment, they can meet the needs of subscribers. The disadvantage is that it can not be.

In the current high speed communication infrastructure, most of the high speed internet services are unidirectional communication, and in a LAN environment, bidirectional communication is basic. In DSL service, a proxy server provided by broadband service provider is located between internet user and service server through DSL modem to retrieve desired information and deliver it to user according to user's needs. do. That is, two-way communication is performed through the proxy server in the center of the broadband service provider. The proxy server takes the information search or communication request of the Internet user and performs it, and the result is returned to the waiting Internet user after receiving the proxy server itself.

The above-mentioned shortage of Internet Protocol (IP) addresses will be described in more detail.

In order to enable two-way communication, you must have an IP address that is on the Internet. The current IP address scheme was established in 1981 and has a 4-bit, 32-bit data structure of 8 bits each. IP addresses are currently classified into three classes.

Class A (Class): A total of 126 dogs and one of the 16,777,214 Class A networks ^(224-2) may be a single IP address. However, as of January 1998, half of these were already allocated to US corporations and government agencies in the early days, with the remainder "reserved."

Class B: There are 16383 in total and 65534 {(256 × 256) -2} IP addresses are available in one Class A network. However, as of January 1998, about 12,000 of these have already been registered and used, and there is a separate IP Management Organization (APNIC) in the Asia-Pacific region. Has been suspended since the second half of 1999.

Class C: There are 2097152 in total, and 254 IPs are available in one Class C network. However, of these, 800,000, or 40%, are already registered and in use, of which the class C IP networks allocated to the Asia-Pacific region as of November 1998 were 202.0.0.0-202.255.255.0, 203.255.255.0, and 210.0. .0.0- 210.255.255.0 and 211.0.0.0-211.255.255.0

As mentioned above, IP addresses available in Korea are Class B or Class C address groups. Currently, Class B group IP addresses are not additionally supplied to Korea in the Asia-Pacific region.

The present invention has been made in view of the above-described disadvantages of the conventional Internet business.

It is an object of the present invention to provide a system and method for implementing a local area Internet business by a local server according to the present invention at a low cost.

It is yet another object of the present invention to provide a method for solving the depleted IP address problem.

Another object of the present invention is to provide a solution that can be used to build an efficient and effective high-speed Internet network while still using the existing net environment.

In order to achieve the above object of the present invention, a decentralized Internet business implementation system according to the present invention is connected to an ISP providing a high-speed Internet service network and a backbone network provided by an ISP, and has a Linux-based NAPT function. A plurality of local servers, a plurality of personal computers connected to the local server to enable bi-directional high-speed Internet, and a plurality of local carriers connected to the local server to link local portals and contents through the local server. And a connection of the plurality of personal computers and the plurality of local operators via the local server are connected through the same hub.

In addition, the local decentralized Internet business implementation method according to the present invention, the step of pulling the public IP of the provider (ISP) that provides a high-speed Internet service network, and attempting to access the public IP from the outside by the Internet user personal computer, Redirecting an IP by a plurality of local servers equipped with a Linux-based NAPT function connected to a backbone network provided by the ISP, and providing a fake IP from the local server onto the Internet user personal computer. The Internet user exchanges information through TELNET and is also connected to the user's office computer.

Hereinafter, with reference to the accompanying drawings for a detailed description of the present invention will be described in detail an embodiment of the present invention.

1 is a diagram illustrating a region based internet business solution by a local server according to the present invention.

In FIG. 1, a local-based local server 100 according to the present invention includes a broadband Internet service provider 101 through a dedicated network 101A, an Internet user 102 through a wired / wireless network 102B, and a wired / wireless network 103C. It is connected to the local providers 104 through the information provider (103) and the wired / wireless network (104D) through the ().

The local server 100 receives a public IP from the high speed Internet service provider (ISP) 101 through the dedicated network 101A. The local server 100 is a Linux server equipped with a network address translation (NAPT) function.

A network address translation function (NAPT) will be described in more detail as a method for alleviating the IP address exhaustion employed by the local server 100 of the present invention.

NAPT is based on the concept of address reuse in private networks, and works by mapping the reusable IP address of the leaf domain to the unique host required to communicate with hosts on other networks. It is difficult to make full use of reusable addresses in private networks without using NAPT's features.

When connected to the Internet, NAPT handles these tasks in one step, eliminating the need to visit individual hosts on the network to translate IP addresses. NAPT uses classless CIDR (Policyless) policy that assigns IP addresses that aggregate reusable addressing and routing information for multiple networks into a single routing table entry to increase the efficiency (reduced size) of the Internet routing table. Inter-Domain Routing

NAPT supports the following two address translation methods. That is, the dynamic address allocation method and the static address allocation are supported.

To explain how NAPT works,

1) Addresses in the stub domain can be reused by any other stub domain. In other words, a single Class A address is used for multiple stub domains. The NAPT is located at the exit point between the stub domain and the backbone. If more than one exit point exists, each NAPT has the same conversion table. That is, the stub and other stubs are internally assigned 10.0.0.0 as class A, the stub's NAPT is assigned 198.76.29.0 as class C, and the other stub's NAPT is 198.76.28.0 as class C. lets do it.

When the stub host 10.33.96.5 wants to send a packet to another stub host 10.81.13.22, it sends the packet to the first primary router using the destination's unique address of 198.76.28.4. The stub router has a static route of 198.76.0.0 and packets are sent on the link. However, NAPT converts source 10.33.96.5 to its original 198.76.29.7 before the package is sent.

As such, NAPT is an address change function that enables private networks to be used globally by using dynamic and static address allocation mechanisms to overcome the shortcomings caused by exhaustion of Internet addresses.

2 is a diagram illustrating a NATP function mounted on a local server according to the present invention.

The local server 200 according to the present invention is connected to a high speed internet service provider 201 through a service network 201A. When the internet user 203 accesses, for example, apt.kapt.co.kr (210.101.204.205) (authorized IP) through the local server 200, the Internet user 203 is redirected to 192.168.100.3 according to the redirection of the entrance. That is, the Internet user 203 is connected to apt.kapt.co.kr to 210.101.204.205:800, but is actually reconnected to 192.168.100.3:80 by the local server 200 equipped with the NAPT function. This does not appear to internet users (masquerading). In addition, biz.kapt.co.kr visible to external accessors at 210.101.204.205:8010 is reassigned and serviced at 192.168.100.12:80.

By this designation, by the local server 200 equipped with the NAPT function according to the present invention,

The web server 202 of apt.kapt.co.kr has a private IP of 192.168.100.3,

The personal computer of the Internet user 203 will have a private IP of 192.168.100.4,

Another biz.kapt.co.kr web server 204 will have a private IP of 192.168.100.12,

Another Internet user's personal computer connected to another web server 204 would have a private IP of 192.168.100.26.

Internet users can connect to their office computers via TELNET (Telecommunications Network) through their personal computers at home. The user pretends to be a user of 210.101.240.205, but the actual data is redirected to the user's personal computer by the local server according to the present invention equipped with the Linux-based NAPT function.

3 is a view for explaining a LAN environment construction method according to the present invention using an existing telephone line.

In the plurality of local servers 300 according to the present invention equipped with the Linux-based NAPT function, a hub (301), which is an aggregation device for connecting a plurality of nodes, an internet user 303 through the hub, and information provision A router 302 for connecting a network of an operator, a local operator, etc., with another external network, and a wired / wireless bridge for connecting with a local server of the present invention for bridging a wired or wireless network for a remote Internet user. 304 is connected.

An Internet dedicated line is installed from the ISP to the main distribution frame of the residential area (eg apartment building). In case of short distance (within 250 meters), establish a LAN environment connecting local server and group living area through existing telephone line using HOME-PNA (Phone Line Network Alliance) equipment such as T / LAN. It establishes LAN environment by connecting wired / wireless bridge between local server and group residential area through wired / wireless bridge. In the LAN environment configured as described above, each subscriber connected to the same hub can be provided with high-speed Internet service from a local server at a speed of 10 Mbps, and broad application support is possible.

According to the area-based Internet business solution system by the local server according to the present invention, the Internet local operator can share the rental fee to the subscriber when using the leased line drawn from the backbone network. Much less than the Internet business by sales method. In addition, by having a web server at home, which is impossible in the proxy server method adopted by the existing portal site, it enables the Internet business as if it is an office environment, and solves the exhausted IP address problem. It is possible to increase the efficiency, and economically effective because it builds a local-based Internet business solution by a local server according to the present invention under a given existing network environment.
