Abstract

PURPOSE:To realize simultaneous communication between networks other than a network during communication at present by providing a processor operated by a learning function with multi-task so as to control the signal. CONSTITUTION:When a signal is sent from a computer 12 to a computer 14, a signal is sent from the computer 12 to a network 11 through a network connection section 10. A signal entering the network connection section 10 is decoded by a processor section 9 and gives the signal to the network connection section of a network 13 connecting to the computer 14. The network connection section receiving the signal gives the signal to the network 13. On the other hand, when the signal from a network 15 toward a network 16 is fed to a network controller 8 simultaneously, simultaneous transmission reception is implemented by using the processor 9 operated in multi-task.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a network control device.

BACKGROUND OF THE INVENTION In recent years, with the aim of improving productivity, the number of computers being introduced has increased, and these computers have come to be positioned as the center of all business operations through information communication through network connections.

A conventional network control device and its control method will be described below.

Figure 2 shows the IEEE802 O3I standard, which is an international standard.
．． 3 (C3MA/CD system). 1 is a computer, 2 is a network connected to computer 1, 3 is a bridge connected to network 2, 4 is a backbone network connecting each network, 5 is a bridge connected to backbone network 4, 6 is a network connected to bridge 5, 7 is a This is a computer connected to network 6.

In the network configured as above, the flow of signals will be explained below.

First, when trying to send a signal from computer 1 to computer 7, the signal flows through network 2, and bridge 3
The signal flows to the backbone network 4 via.

The signal then flows through the bridge 5 to the network 6 and reaches the computer 7. It is assumed that each bridge knows, by its learning function, the network to which the computer 7, which is the destination of the signal, is connected. The bridge has a learning function that remembers the computer that sent the signal, and has a filtering function that prevents the signal from being sent to unrelated networks.

However, in the conventional configuration described above, while a signal is flowing on the bank bone network, the signal cannot be sent from the fringe to the bank pawn network, and the signal is connected to a network unrelated to that signal. There was an issue with the computer not being able to send signals.

The present invention solves the above-mentioned conventional problems, and is a network that can simultaneously send and receive signals between networks other than the network to which the sending computer is connected and the network to which the receiving computer is connected. The purpose of this invention is to provide a control device and its control method.

Means for Solving the Problems To achieve this object, the network control device of the present invention is equipped with a learning function and a processor that operates in multitasking, and has a configuration for controlling signals.

Effect: With this configuration, in order to realize simultaneous communication between multiple networks, the learning function of this network control device determines whether the combination unit that sent or received the signal is connected to the same network. I know. By using this learning function and control by the Flosser, which operates in multi-task mode, it is possible to simultaneously communicate with networks other than the currently communicating network.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a network configuration diagram in an embodiment of the present invention.

In FIG. 1, 8 is a network control device, 9 is a processor section of the network control device, 10 is a network connection section of the network control device, 11 is a network,
12 is a computer connected to the network 11;
3 is a network, 14 is a computer connected to the network 13, 15 is a network, and 16 is a network.

The operation of signal control in this embodiment configured as described above will be described below.

First, from computer 12 to computer 14 in FIG.
When sending a signal to the computer 12 , the signal flows from the computer 12 to the network 11 and passes to the network connection section 10 . The processor section 9 decodes the signal entering the network connection section 10 and passes the signal to the network connection section of the network 13 to which the computer 14 is connected. The network connection to which the signal has been passed passes the signal to the network 13. On the other hand, when signals from the network 15 to the network 16 flow to the network control device 8 at the same time, the processor 9 operating in multitasking performs simultaneous transmission and reception.

Effects of the Invention As described above, according to this embodiment, by connecting each network to a network control device and controlling signals by the network control device, signals can be transmitted and received between a plurality of networks at the same time. In conventional network configurations, as the network becomes more complex and the number of connected computers increases, signal collisions occur more frequently and communication response between networks deteriorates. According to this embodiment, within the control capability of the network control device, signal collisions do not occur and the communication response does not deteriorate.
