A method and a device for processing a failure of path computation requested by a client (PCC). The method for processing a failure of a path computation requested by a PCC comprises: a path computation element (PCE) receiving a request for a path computation according to a constraint condition sent by the PCC; and the PCE performing, according to the request, the path computation, and returning a path computation result to the PCC, and if the path computation according to the constraint condition fails, the path computation result containing guidance suggestions for the path computation failure.
