Disclosed are a method, a device and a system for generating a service path. The method comprises: a path computation element (PCE) receiving a path computation request (PCReq) message sent by a path computation client (PCC), the PCReq message comprising network function virtualization (NFV) function demand information; and the PCE generating a service path according to a network function virtualization database (NFVDB), an NFV function entity conforming to the NFV function demand information is on the service path. The embodiments of the present invention have the following beneficial effects: when a user service is changed, a PCE obtains NFV function demand information in a PCReq message sent by a PCC, and generates, according to an NFVDB, a service path conforming to an NFV function entity required in the NFV function demand information, so as to dynamically configure a service path of a user, and compared with static configuration of the service path of the user, the difficulty of configuration and maintenance is reduced. |
