Embodiment 1

[0095] The link status of communication port PORT1 and communication port PORT2 remains LINK UP

[0096] 1. The adaptive selection of communication port PORT1 is real-time update, and the adaptive selection of communication port PORT2 is delayed update;

[0097] 2. The communication port PORT1 waits for the next cycle to continue scanning the link status of the communication port PORT1;

[0098] 3. Read the LINK DOWN timer of the communication port PORT2, if the timer is not zero, clear it, and wait for the next cycle to continue scanning the link status of the communication port PORT2;

[0099] 4. The communication port LINK UP status update is completed.

Embodiment 2

[0101] The link status of communication port PORT1 and communication port PORT2 remains LINK UP

[0102] 1. The adaptive selection of communication port PORT1 is real-time update, and the adaptive selection of communication port PORT2 is delayed update;

[0103] 2. The communication port PORT1 waits for the next cycle to continue scanning the link status of the communication port PORT1;

[0104]3. Accumulate the LINK DOWN timer of the communication port PORT2, and wait for the next cycle to continue scanning the link status of the communication port PORT2;

[0105] 4. The communication port LINK UP status update is completed.

Embodiment 3

[0107] The link status of communication port PORT1 and communication port PORT2 changes from LINK UP to LINKDOWN

[0108] 1. The adaptive selection of communication port PORT1 is real-time update, and the adaptive selection of communication port PORT2 is delayed update;

[0109] 2. Report the link status of the communication port PORT1 to the business module, and wait for the next cycle to continue scanning the link status of the communication port PORT1;

[0110] 3. Accumulate the LINK DOWN timer of the communication port PORT2. If the link status of the port PORT2 remains LINK DOWN and reaches the specified threshold time, report the current LINK DOWN status to the business module; otherwise, the default link status of the communication port PORT2 is LINK UP, do not report to the business module, and scan in the next cycle.

[0111] 4. The status update of the communication port from LINK UP to LINK DOWN is completed.

Abstract

The invention provides a link state update method and device of a communication port. The update method comprises the following steps: detecting communication quality of the communication port to obtain a detection result; and determining a strategy for updating the state of the communication port according to the detection result. Through the technical scheme provided by the invention, the link state of the communication port can be updated in real time or the link state of the communication port can be updated in delay according to the communication quality of the communication port. The fast convergence and the anti-interference performance of the communication equipment are both taken into consideration in the link state update method disclosed by the invention, and the stable work of the communication equipment is guaranteed.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for updating the link state of a communication port. Background technique [0002] At present, the communication port link status update generally adopts a synchronization mechanism. By reading the actual link status of the communication port, the status is updated to the software table synchronously, and the business module is notified. The business module passes the configuration of the current device and the communication port. Link status to perform related business actions. Usually, the faster the update speed is, the more sensitive the device response speed will be, and the anti-interference and robustness of the device will be correspondingly worse. [0003] In a network environment with poor link quality, a normal flash disconnection of the communication port, if the link status of the communication port is reported in real time, for some services, the se...
