1. A link determining method for an optical packet switching system, comprising:
parsing out, by a control manager, routing information carried in an optical label of an optical packet before switching;
generating, by the control manager, reference optical label information and an enabling signal according to the routing information;
sending, by the control manager, the reference optical label information and the enabling signal to a link determining device;
determining, by the control manager when the enabling signal is active, whether an alarm signal sent by the link determining device is received; and
determining, by the control manager according to the alarm signal if the alarm signal sent by the link determining device is received, whether a link corresponding to the alarm signal is abnormal.
