Patent ID: 8023527

Claim:
A method for adjusting timeslot fragments of multiple links in an optical network by an adjustment apparatus, the method comprising: obtaining, by a table establishment module of the adjustment apparatus, link information of multiple links necessary for timeslot fragment adjustment; calculating, by the table establishment module, adjusted link information of each link necessary for the timeslot fragment adjustment according to the link information; and adjusting a timeslot allocation of said each link according to the adjusted link information; wherein the step of adjusting a timeslot allocation of said each link according to the adjusted link information further includes the steps of: establishing, by an adjustment module of the adjustment apparatus, a new path for a pending adjustment service according to the adjusted link information, wherein the new path includes multiple links necessary for timeslot fragment adjustment, wherein the new path passes through multiple nodes, each two adjacent links of the multiple links being connected by one node of the multiple nodes respectively, the node that connects two adjacent links being different for each two adjacent links; switching, by the adjustment module, the pending adjustment service from an original path to the new path; and removing, by the adjustment module, the original path of the pending adjustment service.
