method and apparatus for regulating optical synchronous digital hierarchy network service

摘要

The present invention discloses a method and an apparatus for adjusting a service of optical synchronous digital hierarchy network, and the method for adjusting a service is used to adjust the cross path among the space-division module and at least two time-division modules, which comprises: at first configuring the input time-slot space-division cross path to the time-division module after adjustment in space-division module and the time-division cross path of the time-division module after adjustment; and configuring the output time-slot space-division cross path from the time-division module after adjustment in space-division module; deleting the original cross path formed by the time-division module before adjustment. The apparatus comprises: a first configuration unit used to configure the input time-slot space-division cross path to the time-division module after adjustment in space-division module and the time-division cross path of the time-division module after adjustment; a second configuration unit configuring the output time-slot space-division cross path from the time-division module after adjustment in the space-division module; deleting the original cross path formed by the time-division module before adjustment. The present invention can reduce the service instant-interrupt time to be less than 50ms.
