AI Technical Summary

Technical Problem

The existing ERPS ring network solution based on aggregation group connections suffers from reduced actual available bandwidth when some physical links experience connectivity failures. This leads to packet loss and service interruption when service traffic exceeds the actual available bandwidth, resulting in link instability.

Method used

By obtaining the number of faulty links in the connection links, the bandwidth utilization of the aggregation group is calculated, and when the utilization reaches a preset threshold, the connection link is switched from the first aggregation group to the ring protection link, and the status flag is updated to achieve stable switching.

Benefits of technology

It enables timely switching to the ring-protected link when the bandwidth utilization of the aggregation group exceeds the threshold, ensuring the stability of the link and avoiding packet loss and service interruption.

Abstract

The invention relates to a link switching method and device, equipment and a medium, and relates to the technical field of communication. The method comprises the following steps: acquiring a first number of fault links in a first aggregation group in connection links; based on the first number, the total number of links in the first aggregation group, the bandwidth occupied by the flow and the first bandwidth of each physical link in the first aggregation group, determining a first bandwidth utilization rate corresponding to the first aggregation group; under the condition that the first bandwidth utilization rate is greater than or equal to a preset switching threshold value, updating a state flag bit of the first aggregation group, and switching the connection link from the first aggregation group to a second aggregation group; wherein the second aggregation group is a ring protection link. By adopting the method, the stability of the link can be ensured.
