ADSL data device of providing IpoA, PPPoA or PPPoE services of logging on network by dialing operation through Ethernet router

Abstract

DHCP server built in ADSL data device makes at least more than one computer obtain legal IP address and relevant settings from Internet service provider (ISP) without need of installing any driving program and application software and by means of DHCP function provides by operation system through DHCP server and ADSL wire. Then, using DHCP server sets up IP address and related settings corresponding to each computer. After each computer obtains legal setting values, function of logging on network in IpoA, PPPoA or PPPoE modes is provided.

Description

technical field [0001] The present invention is an ADSL modem, especially an ADSL modem that can provide IPoA, PPPoA or PPPoE dial-up Internet service through Ethernet without installing any driver program and application software on the computer. Background technique [0002] In recent years, the Internet (Internet) has developed vigorously, especially Word Wide Web (abbreviated as WWW). In addition to providing traditional e-mail transmission services, it also combines various multimedia services such as voice, pictures, and dynamic images. Accompanied by such multimedia services, there is an extremely large amount of data. Therefore, users of the traditional dial-up telephone network can no longer meet the 28.8, 33.6 or 56kps transmission rate provided by the traditional modem (Modem), or even Users on the local area network and ISDN cannot satisfy the transmission rate provided by the network. [0003] In order to obtain higher-speed data access capabilities, Internet s...

Problems solved by technology

[0006] (1) ADSL modem (Modem): The user connects the ADSL modem with his personal computer to directly access the Internet through the ADSL system, send, receive or browse data. This way of accessing the Internet through the ADSL modem is relatively expensive. Low, but it can only connect a single personal computer to the Internet, and cannot provide the service of connecting multiple personal computers to the Internet at the same time. In addition, when the user installs the ADSL modem to the personal computer, he must also install the relevant Dial-up software, drivers and applications, for general users, are often difficult to install because they cannot be successfully installed, causing great troubles in use. For developers, it is necessary to provide Various drivers and application programs also increase the difficulty of design and update

[0007] (2) ADSL router (Router): The user connects the ADSL router with the local area network (local network) server to which it belongs, because a network address translation technology (Network Address Translation, Hereinafter referred to as NAT), the transmission control protocol (Transmission Control Protocol / Internet Protocol, hereinafter referred to as TCP / IP) of computer equipment in the local network can be used to share the common Internet through this address translation technology. Communication protocol (IP) address, so many users on the local area network can connect to the Internet through the router, send and receive or browse data, but the users of the ADSL router must install related dial-up software, drivers and applications In addition to the program, it is necessary to pay more than the cost of using the ADSL modem, resulting in high cost of use, and each computer in the local area network can only obtain the translated address, and cannot obtain the legal IP address, so , for some application software that must use a legal IP address (such as: online games and VoIP services), users cannot use the software through the ADSL system

Even if this problem can be solved through some special settings, it is still too difficult for ordinary users to achieve
