Method for realizing automatic and smooth switch among different network topology structures and network device thereof

Abstract

The invention discloses a method for realizing automatic and smooth switch among various network topology structures and network device thereof; A computer or the network device is connected with a physical-layer chip by a network isolating transformator connecting switch unit; the physical-layer chip processes network signal and sends the signal to a network switching chip connected with the physical-layer chip; the network switching chip is applied to the virtual local-area network technology (VLAN) and is controlled by the control signal of a control unit for carrying out switch among different network topology structures and realizing different network channels formed by a plurality of computers and network devices. The method realizes instant dynamic switch of the different network topology structures and solves the problems that frequent network-cable jumping can easily breakdown the network devices, the abrasion is high, and the service life and working performance of the network devices are affected by the traditional method of group network switch. By applying the physical-layer chip and the switching chip, and combining a control technique of a mono-plate processor, a designing proposal of a digitized circuit which mainly takes an integrated circuit chip as the circuit is formed, a universal network switch is replaced, fund repeatable investment is reduced and the application efficiency is improved.

Description

technical field [0001] The invention provides a method for realizing automatic and smooth switching of various network topology structures, and also discloses a device adapted to the method, which is a network device for realizing remote access, and belongs to the technical field of computer network communication. Background technique [0002] According to the network topology structure, the corresponding network topology requirements are realized by applying multiple unmanaged switches or switches supporting virtual local area network technology (VLAN). However, since a single network switch device supports the partitionable virtual local area network technology, the network interface is in a static state after the VLAN ID identity value is set during the application process, and only a fixed topology can exist in a single switch. If the network topology changes, it must be connected to the configuration port (Console) of the switch to complete the relevant parameter settin...
