<p>Disclosed are a global concurrent optimization method, device and system for a label switching path. The method includes: a path calculation element calculating the path of each LSP in a group of LSPs in a network, grouping each LSP, and sequencing the setup and/or delete order of each LSP in the subgroup where it belongs, wherein each LSP belongs to one subgroup; and the path calculation element sending a path calculation response message to a path calculation client, the path calculation response message carrying the path calculation result of each LSP in the group of LSPs, the grouping information of each LSP and the setup and/or delete order of each LSP in the subgroup where it belongs. The present invention divides a large number of LSPs into a plurality of optimization/re-optimization subgroups, and specifies a setup and/or delete order for an LSP in each subgroup, and while in optimization/re-optimization of the large number of LSPs using GCO, the operations of the subgroups are concurrently performed, to improve the optimization/re-optimization efficiency.</p> |
