Abstract:
A method for allocating a global label is provided, including: receiving, by a controller, a first message sent by a forwarding apparatus, where the first message carries a first label range, multiple labels included in the first label range are a subset of multiple labels included in a label space of the forwarding apparatus, and the first label range is not equal to the label space of the forwarding apparatus; and allocating, by the controller, a global label to the forwarding apparatus according to the first label range carried in the first message, where the global label is a label in the first label range. In addition, a method for obtaining a global label, a controller, and a forwarding apparatus are further provided. The foregoing solutions improve efficiency of global label allocation.

Claim (Index 16):
The controller according to  claim 15 , wherein the first label range comprises a label that has been allocated by the forwarding apparatus to a first label switched path, the forwarding apparatus is a node on the first label switched path, the controller further comprises a first sending unit, the first sending unit is configured to send a second message to the forwarding apparatus after the first receiving unit receives the first message and before the allocation unit allocates the global label to the forwarding apparatus, the second message comprises a second label range, the second label range comprises multiple labels, the second label range is a subset of the first label range, the second message is used to instruct the forwarding apparatus to allocate a new label to a second label switched path, the new label is used to replace a label that has been allocated by the forwarding apparatus to the second label switched path, the new label is outside the second label range, the second label switched path is a subset of the first label switched path, the label that has been allocated by the forwarding apparatus to the second label switched path is a subset of the second label range, and the global label is a label in the second label range.
