AI Technical Summary

Technical Problem

Existing WiFi 7 routers lack an effective inter-link arbitration mechanism in MLO scenarios with multiple links. This can lead to one link monopolizing the router's processing resources due to sudden traffic surges, while events on another link accumulate and expire. Furthermore, the lack of consideration for differences in event types results in frequent inter-link context switching, impacting resource processing efficiency.

Method used

By obtaining the link characteristic values ​​of each connection link to generate a global bitmap index, and combining the virtual runtime and the number of ready events to calculate the resource scheduling value, effective arbitration between links is achieved, and batch scheduling is performed using the event deadline to reduce context switching.

Benefits of technology

It improves the resource processing efficiency of routing devices, reduces frequent switching between links, and enhances resource utilization and event completion rate.

Abstract

This invention provides a multi-link device scheduling and control method, system, and routing device, relating to the field of routing device resource scheduling and control. In the link scheduling process, this method uses the virtual runtime and the number of ready events of each connected link to calculate the resource scheduling value to obtain the target connected link, fully considering the resource scheduling situation of multiple link devices and achieving effective arbitration between links. In the event scheduling process, the method uses the event deadline to perform batch scheduling processing of target events in the target connected link, significantly reducing context switching and improving resource processing efficiency.
