Secure computer network with a network screen

摘要

This invention takes advantage of the capability to keep secured physical and logical addresses of the internal subscribers of the local network using a special network screen for the packets exchanged between the network segments and using a special program to control the packets communication processes between the network interfaces. The program of control resolves the task of information delivery using special codes in the packet headers that are different from their logical and physical addresses. The network screen has a special interface to change, control and tune filter parameters.
