Network address management system and method with bidirectional cable

Abstract

A bidirectional cable network address management system and its method is to manage the internal address of the client terminal entering into network. The client terminal includes a bidirectional modem with a first access control address, a computer linked on it with a second access control address, a modem head-end, a dynamic host composite mode protocol server connected to the modem head-end receiving the first and second access control address, allocating and sending the first and second IP address of the client terminal according to the first and second access address. If the first and second access control addresses are not stored in the dynamic composite mode protocol server, the IP address is the unregistered first IP addrss, the second IP address is the unregistered second IP address.

Description

technical field [0001] The present invention relates to a two-way cable network address management system and method, which is suitable for an Internet service provider (Internet Service Provider, ISP) to manage the Internet connection address of at least one client's two-way cable Internet connection, and is especially suitable for The client's two-way cable modem and the computer's media access control address assign and manage Internet connection addresses. Background technique [0002] With the development of the Internet, broadband Internet access is becoming more and more popular. In particular, using the cable modem (cable modem) for short for CM to access the Internet, because the data is transmitted using the coaxial cable of the cable TV system, its bandwidth is wider than the bandwidth of the telephone line used in the general dial-up network, so It can improve the speed of data transmission and become the best choice for broadband Internet access.

Problems solved by technology

[0006] However, in these prior art cable network automatic login services, the ISP has no way of managing the client except for the application data input by the client. For example, the ISP cannot know the computer and the two-way CM type used by the client to access the Internet. , and whether the client who has not logged in will definitely connect to the cable Internet service login server to log in cannot be controlled; it may even cause the client who has not obtained the right to access the Internet to use the right to temporarily connect to other Internet connections, or arbitrarily Stealing the account of other logged-in clients to connect, thus causing a dead end in connection security

Therefore, the prior art two-way cable Internet login service is not only difficult in connection management, but also the provision of temporary connection rights is likely to cause connection security loopholes
