摘要
A cross-domain clock synchronization method, device and system and a computer storage medium, which are applied to a cross-domain synchronization network. A Path Calculate Element (PCE) exchanges a clock synchronization type with a controller participating in clock synchronization path calculation to match the clock synchronization type supported by the PCE and the controller; the PCE acquires physical topological information of the cross-domain synchronization network; the PCE acquires synchronization information of synchronization nodes of the cross-domain synchronization network and/or hop number information between the synchronization nodes; the PCE calculates a clock synchronization path of the cross-domain synchronization network according to the physical topological information as well as the synchronization information and/or the hop number information; and the PCE sends the clock synchronization path to the controller according to the physical topological information to enable the controller to send a clock synchronization instruction to synchronization nodes on the clock synchronization path.
