Abstract:
1. A node, comprising: a control module, configured to generate synchronization information and Optical Burst (OB) configuration information; at least one synchronization processing module, configured to perform a synchronization process on OB paths at one or more wavelengths according to the synchronization information; and a cross-connection module, configured to perform, according to the OB configuration information, a cross-connection process on the OB paths, on which the synchronization process has been performed; wherein the control module comprises: at least one detecting unit, configured to detect an OB frame header clock from a pre-separated signal, and send the OB frame header clock to the synchronization processing module; a generating unit, configured to perform a frequency locking process and a delaying process on the OB frame header clock to generate a new OB frame header clock, and send the new OB frame header clock to the synchronization processing module; an OB time-slot clock generating module, configured to generate a new OB time-slot clock by using a start position of the new OB frame header clock as a reference; and a configuration information generating unit, configured to generate the OB configuration information according to preset OB path configuration information, the new OB frame header clock, and the new OB time-slot clock, and send the OB configuration information to the cross-connection module, wherein the synchronization information at least comprises the OB frame header clock and the new OB frame header clock.
