Abstract:
The present invention discloses a method for realizing cross-connect of optical channel data units (ODUk), which comprises: mapping the accessed services to the ODUk, and mapping the services mapped to the ODUk to the ODUk time slot frames according to the requirements of the time slot frames; mapping the ODUk time slot frames to the intermediate frame structures; performing the cross-connect for ODUk services in the intermediate frame structures. The present invention also discloses an apparatus for realizing cross-connect of ODUk. The present invention directly supports cross-connect of ODUk, so as to realize simple scheduling for the Optical Transport Network (OTN) services, and improve the resource utilization factor and the integration level.
