Description

Semi router and internet system using same

The present invention relates to a semi-router, and more particularly to a semi-router that enables external Internet communication by simply connecting a LAN cable or communication port without having a transmission device, when several people communicate in the apartment or apartment. It is about.

Generally, in order to communicate with the outside, each one of the modem, Asymmetric Digital Subscribe Line (hereinafter referred to as "ADSL"), Integrated service digital network (hereinafter referred to as "ISDN"), and Public Switched Telephone Network (hereinafter referred to as "PSTN") You must receive the line through any one of the means of communication, such as CATV (CAble TeleVision) modem, leased line, or Digital Broadcasting Satellite (hereinafter referred to as "DBS").

In this case, in order to communicate with the outside by connecting a plurality of people, a router must be installed to perform a function of translating addresses between networks or converting according to a protocol. At this time, a hub for switching a plurality of computers is connected to the input terminal of the router. The output terminal of the router is connected to a dedicated line directly connected to the Internet or communication equipment such as ADSL and ISDN.

However, as the demand for communication facilities increases in general homes, small and medium-sized buildings or tenement apartments, there is an increasing demand to receive and use one line for each computer in and out of the building. In order to solve the problem, a transmission device such as a hub and a router must be uniformly provided.

The present invention has been made to solve the above problems, and provides a simplified semi-router and an internet system using the same to receive a single line, such as ISDN, PSTN, CATV modem, leased line on the Internet communication, and to write in multiple lines. Its purpose is to.

The purpose of the above is to provide a plurality of LAN ports that can be connected to the LAN cable of a plurality of terminals, the MUX for switching the connection of the LAN port, the CPU in charge of the overall control to deliver the electrical signal transmitted from the public network to a given IP And independently configured externally to give email addresses to LANChip, ROM to store a set of algorithms performed to operate the system, RAM to temporarily store data, and multiple IPs divided from one IP. It is characterized by an e-mail server and an external proxy server repeater for each IP.

Hereinafter, a semi-router according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a semi-router and an Internet system using the same according to an embodiment of the present invention.

Explanation of symbols on the main parts of the drawings

1 to N: terminal 10: semi-router

11 to 1N: LAN port 21: MUX

22: LAN chip 23: CPU

24: ROM 25: RAM

26: LAN port 27: Serial port

The configuration of the semi-router of the present invention, as shown in Figure 1, a plurality of terminals (1 to N); A plurality of LAN ports 11 to 1N for connecting LAN cables extending from the plurality of terminals 1 to N, a MUX 21 for switching the connection of the LAN ports 11 to 1N, and a public network ( 30, the CPU 23 and LANChip 22, which are in charge of the overall control to deliver the electric signals transmitted from the network to a given IP (Internet Protocol), and a ROM 24 which stores a series of algorithms to be operated to operate the system. And a RAM 25 for temporarily storing data, a LAN port 26 for connecting DSL, CATV, and DBS (digital broadcasting satellite) transmission means, and a serial for connecting ISDN or PSTN and DBS transmission means. Semi-router 10 consisting of a port 27; A transmission device 30 connected to the LAN port 26 or the serial port 27 of the semi-router 10 and connected to the public network 40; E-mail server 51 installed outside the transmission equipment 30 to redistribute a plurality of IPs divided into a plurality of divided IPs or externally installed when you want to have a separate IP It consists of a proxy server (Proxy server) repeater (52).

The LANChip 22 integrates a chip of a hub function and a chip of a router function to perform a function of a hub and a router.

The transmission device 30 allows a user to select among DSL {ADSL (Asymmetric DSL), HDSL, VDSL, IDSL, SDSL}, CATV, DBS, ISDN, PSTN.

Among them, if the user selects the DSL or CATV transmission equipment, the user connects to the LAN port 26. If the user selects the DBS, the user uses the serial port 27 to transmit the contents at a somewhat slower speed. The content to be received is connected to the LAN port 26 to be transmitted at high speed.

If the user selects ISDN or PSTN, the user connects to the serial port 27.

The e-mail server 51 is configured to redistribute the first one line to the user of the terminal 1 to N. The e-mail server 51 receives all addresses from the public network 40 and redistributes them to the user.

The proxy server repeater 52 is a process for giving an IP in a similar manner, but may be given to a content provider.

In addition, the proxy server repeater 52 may be provided with an IP by setting an IP as a proxy server by a web browser and a content provider owned by the user without special installation.

Therefore, the use of the semi-router 10 configured as described above and the Internet system using the same is as follows.

First, when a plurality of users (1 to N) in a building connect LAN cables to each LAN port (11 to 1N), each computer is divided by an e-mail server 51 that connects the IP with the entire external IP. The master is assigned an address and can be assigned an IP by the proxy server repeater 52 if a unique IP is required.

As a result, not only an Internet connection but also a mail sent from the other party can be received and the mail can be sent to the other party.

Since the semi-router as described above does not have to purchase a separate hub, and the semi-router itself has a built-in function for transmission, so there is no need to purchase a transmission device such as a modem, thereby reducing costs.

As described above, by providing a semi-router according to the present invention, a plurality of users of an alliance or an apartment do not have to separately provide a transmission means, thereby reducing the economic burden of purchasing communication equipment, It is a very useful invention in the communication device manufacturing industry because it has the effect of increasing the product purchasing power.
