Embodiment 1

[0038] according to figure 1 As shown, it consists of 12 switching units and 1 control unit. In each switching unit, the computer terminal is connected to the network switching chip 3 (model MAX4892ETX) through the network isolation transformer 2 (model 13F-2003NL), and the network switching chip 3 Respectively through the network isolation transformer 4, 14 (model 13F-2003NL) to connect with the internal network or external network to form a network channel;

[0039] The input end of the physical layer chip 6 (model RTL8208BF) is connected to the network switching chip 3 by a control bus, and the output end of the physical layer chip 6 is respectively connected to the internal network, the external network, and the computer terminal port light to receive data messages from the network switching chip 3 Trigger the signal, perform signal loopback processing, and send it to each network port light respectively.

[0040]The control unit is composed of a microprocessor (model AT8...

Abstract

The present invention discloses a two networks packet switching method and a network device. A computer terminal is connected with a network switching chip through a switching isolation transformer, the network switching chip is controlled by control signals of a control unit to perform switching, and network channel between the computer terminal and the internal network or the external network is realized; in the control unit, control signals are input to a microprocessor by switching buttons and a dial switch, and a latch chip is triggered to send control signals to the network switching chip to control the working state. According to the present invention, a digitalization circuit design proposal mainly for integrated circuit chips is formed by applying physical layer chips and switching chips and combining the single board computer control technology without adopting the relay technology, therefore, frequent jumper connections of netting twine in experimental teaching can be performed in the premise of assuring the experiment efficiency and accuracy.

Description

technical field [0001] The invention provides a method for realizing two kinds of network packet switching, and also discloses a device adapted to the method, which is a network device for realizing group or group switching between two network structures, and belongs to the technical field of computer network communication. Background technique [0002] The traditional method jumps the network cable between the internal and external network devices, which takes up the time of plugging and unplugging the network cable and the self-negotiation of the network equipment. Frequent jumping of the network cable is easy to generate instantaneous high voltage, which is easy to break down the network equipment, and the network interface components of the network equipment are generated. Wear and tear will affect the service life and performance of network equipment. [0003] At present, various network equipment manufacturers mainly use two switching modes for network topology switchi...
