Embodiment Construction

[0017] The concrete implementation of the present invention is described below:

[0018] The present invention respectively counts the receiving and sending packet counts (Rcount, Tcount) in the receiving and sending interrupts or other processes driven by the network port, and uses the existing timing program in the system to judge whether the receiving and sending packets are zero at regular intervals. If it is not zero, the count value is cleared. If either the receiving or sending count is zero, the network port is set to the self-loop mode, and a specific packet is sent from the loop. After waiting for the packet to be received by the system for a short time , and then determine whether the receiving and sending packets are zero. If they are not zero, it means that the network port is normal. If one count is zero, reset the network port and re-initialize the network port.

[0019] With the application of the present invention, when the network port is normal, the continuo...

Abstract

The present invention aims to provide a method for improving the working stability of the Ethernet port of a communication device, comprising the following steps: setting global variables to count events reflecting the receiving and sending functions of the network port, and recording them as Rcount and Tcount respectively; regularly checking Rcount, Tcount value; if both Rcount and Tcount are not zero, clear the count and repeat the above steps; if either Rcount or Tcount is zero, set the network port to self-loop mode and send a self-loop test packet ; After a period of delay, close the self-loop mode; judge Rcount, Tcount value; if both are not zero, then return; The port can resume normal work, and then open the system interrupt and return. The invention can detect the abnormal working state of the network port online, reset the network port in time, and make the network port work normally again, thereby improving the stability of the system.

Description

technical field [0001] The invention relates to the stability technology of the equipment in the communication field, in particular to the stability technology of the Ethernet port of the communication equipment. Background technique [0002] The Ethernet port (hereinafter referred to as the network port) is a commonly used interface in communication equipment. The stability of the network port directly determines the system stability of the communication device. When the network port is working, it is mainly responsible for receiving and sending data packets. [0003] The MAC (Media Access Control) layer of the network port controller provides MII (Media Independent Interface), generally connected to the PHY (Physical Layer) chip. The network port generally exchanges and sends data with the system through DMA (direct data access). In the control system of a device with a network port, there is generally a network port driver, and the network port driver realizes the init...
