Patent abstract

This application provides a latency-based transmission path control method, an apparatus, and a system. Device latencies of network node devices on an active transmission path, device latencies of network node devices on a standby transmission path, latencies of links between the network node devices on the active transmission path, and latencies of links between the network node devices on the active transmission path are obtained, and calculation is performed based on the respective device latencies and link latencies to obtain an active transmission path latency and a standby transmission path latency. Then, based on a latency-based switching mechanism, when the active transmission path latency is greater than a switching threshold and the standby transmission path latency is less than the switching threshold, an active-to-standby path switching command is generated.
