Abstract: Embodiments of the present disclosure relate to a method and a device for compensating for a time path. In the embodiments of the present disclosure, on the basis of not changing implemented 1588 synchronization architecture, a compensation unit is added on a service board unit, the compensation unit calculates a compensation time value for asymmetrical reception and transmission of fiber links and transfers the compensation time value into the service board unit, and the service board unit implements automatic compensation according to a port status. The method and the device for compensating for a time path according to the embodiments of the present disclosure may implement automatic compensation for receiving and sending fiber links without manually testing the asymmetry of links node by node, so that the embodiments of the present disclosure can be widely applied in time synchronization networks.

Abstract: A service switching system and a service switching method, where the system includes at least two service processing subracks and at least one optical cross-connect subrack. Each service processing subrack is connected to each optical cross-connect subrack using an optical fiber. Each service processing subrack is configured to perform service switching for an externally inputted service data electrical signal, and then convert it into an optical signal, and send to one or more optical cross-connect subracks, or vice versa. Each optical cross-connect subrack is configured to receive a service data optical signal from one or more service processing subracks and perform optical cross-connection for the service data optical signal, and then output the service data optical signal to the one or more service processing subracks, which reduce interconnection costs of the service switching system.
