Network control method and equipment

Abstract

By using combinations of a plurality of firewall techniques and making these techniques work together appropriately, problems presented with popular use of always-on Internet connections and end-to-end communications using IPv6 are resolved. This flexible manner of applying access control techniques grants favors to corporate network users, resulting from the popular use of always-on Internet connections and IPv6, e.g., the promotion of teleworking and virtual offices. A traffic control computing device which processes control requests from traffic control devices, provided in a network, coordinates the control actions of the individual traffic control devices appropriately.

Description

technical field [0001] The invention relates to a communication control technology in the Internet, in particular to a firewall technology. technical background [0002] When connecting an internal network such as a corporate network to the Internet, a firewall is usually placed between the intranet and the Internet to prevent unauthorized access from the Internet to the intranet. [0003] Assuming that any access from the extranet to the intranet is unauthenticated, the firewall will operate. The current situation is that the Internet is always connected and the use of Ipv6 end-to-end communication is very common. However, in any case, the above assumptions are becoming more and more contradictory to the needs of intranet users. In particular, we look at the following Happening. For example, when a traveling businessman, or a home telecommuter tries to access his or her company's internal network, the firewall considers the access to be unauthorized. [0004] As an examp...

Problems solved by technology

These problems cannot be solved at the same time, even in cases where multiple existing firewall technologies are some simple combination

The reason is that it is not possible t
