Abstract

The invention provides a network data switch and a method for switching the network data forwarding function. Wherein, the network data switch according to the present invention includes: at least one switch unit; a delay unit connected to each of the switch units, for outputting a signal with an effective duration based on the transition edge of the strobe signal output by the switch unit. A reset signal; a network data function switching unit connected to each of the switch units and the delay unit, used for resetting during the period of the reset signal, and performing all operations according to the strobe signal output by the switch unit after resetting Corresponding network data forwarding function. The present invention uses a delay unit to output a reset signal for the network data function switching unit to reset, which can ensure that each circuit of the network data function switching unit is in a normal working state after function switching. Signals are used to gate the corresponding forwarding function modules, thereby realizing function switching without CPU.

Description

technical field [0001] The invention relates to a data forwarding function switching technology of a switch, in particular to a network data switch and a method for switching the network data forwarding function. Background technique [0002] The network data switch integrates multiple data forwarding functions, and each data forwarding function works under the control of the CPU. Although a switch containing a CPU is more intelligent, its matching software and peripheral control system are more complex and costly. For unmanaged Ethernet data communication products, the function switching of data forwarding cannot be performed without a CPU. In order to realize the data forwarding function switching of unmanaged Ethernet data communication products, the current common method is to control the function switching of this type of network data switch through an external PCB board containing a CPU, and the hardware and software costs are very high. Therefore, it is necessary to...
