State reporting control method and device

The invention discloses a state reporting control method, applied to a stateful path computation unit. The method comprises the steps of setting and informing of an initial subscription state of a label switch path (LSP) state report of a path computation client (PCC) node during a process of implementing session initialization on the PCC node; and sending a subscription update request to the PCC node to subscribe or unsubscribe the LSP state report of the PCC node. According to the method, the stateful path computation unit can flexibly control a process that the PCC node reports the LSP state report. The invention also discloses a state reporting control device.
