Method of constructing office work application network and its device

Abstract

The method and device for building the office application network includes following steps. (1) One or multiple servers as the working platform in the internal network system are built by using the diskless networking technique. Each workstation in diskless (or terminal) mode through the platform server is connected to the internal network. (2) Similarly, the platform server and the workstation connection for the external network are built (3) The same workstation is connected to the internal and external networks respectively, by using the invented devices. The invention provides the networking device, which can be disconnected to the internal and external networks physically. The device consists of the network interface switching module and the switching control modules etc. or, the shared connector can be added.

Description

technical field [0001] The invention relates to a computer network technology, in particular to a method and device for constructing an office application network. Background technique [0002] With the wide application of computer networks, the security of network data has become more and more prominent. From various enterprises and commercial fields to key fields such as government, finance, and national defense, they are all facing the threat of network data security issues. There are two main reasons for these threats, one is the malicious attack and intrusion from the external network; the other is the subjective or objective mistakes of insiders. Therefore, it is a requirement in the construction of computer networks to construct a computer network that can not only ensure the safe and reliable operation of the internal network (INTRANET) system, but also ensure that the resources of the external network (such as the Internet, etc.) are fully used. [0003] At present...

Problems solved by technology

But this not only increases the investment cost, but also is inconvenient to use and takes up a large office space

(2) Use software firewall to isolate, this kind of software-based protection is not safe enough

(3) A computer that can connect to the internal network and the external network at the same time and ensure absolute security, but it must include more than two computer hosts, and only share the keyboard, mouse, monitor, etc. This solution is costly and requires simultaneous production and computer upgrades very troublesome

(4) The dual hard disk system is used, and it is operated with a network isolation card. This solution will increase the complexity of the user's operation, and the maintenance workload will be large and there will be loopholes in information exchange.
