The invention discloses a service function chain request processing method, which comprises the following steps of: classifying received service function chain requests, and determining whether the service function chain requests are processed in an optical domain or an electric domain, wherein the service function chain requested by the service function chain request comprises at least one virtual network function (VNF); performing server mapping on the service function chain request allocated to the electric domain or the optical domain for processing, and determining at least one server forrealizing the at least one VNF; and performing time domain planning on the at least one server, and determining a moment when the at least one server processes the at least one VNF. The invention further discloses a service function chain request processing system.
