A control device may allocate a global label for a switch device based on a forwarding equivalent class (FEC), and issue the global label to the switch device.Subsequently, for a packet not carrying the global label, after matching the packet not carrying the global label with the FEC, the switch device may encapsulate the global label for the packet,and forward the packet. For a packet carrying the global label, the switch device may forward the packet carrying the global label by using a global label forwarding entry. |
