AI Technical Summary

Technical Problem

In distributed management structures, the forwarding path of BFD messages in existing technologies is relatively long, which increases processing latency, occupies control channel resources, affects system stability and performance, and makes it difficult to meet the detection needs of large-scale scenarios.

Method used

The main control module distributes keep-alive session parameters to multiple business modules. Each business module independently executes the sending and receiving of probe packets, generates status update information, and the main control module performs distributed link status detection based on this information, reducing the main control computing power consumption and control channel burden.

Benefits of technology

It significantly reduces the processing burden on the main control unit, improves system stability and link status detection performance, reduces traffic consumption in the control channel, and is suitable for large-scale network devices.

Abstract

This application relates to a distributed link state detection method and apparatus. The method includes: a master control module distributing keep-alive session parameters to multiple service modules; each service module, based on the keep-alive session parameters, performing the sending and receiving of probe packets to determine the real-time connection status of a target device; when the real-time connection status changes, the service module generates status update information; and the master control module performs distributed link state detection based on the status update information. The distributed link state detection method and apparatus of this application can significantly reduce the master control computing power consumption and control channel burden, improving the performance and system stability of link state detection.
