The invention provides a method and a switch for forwarding a message. The method for forwarding the message comprises the steps that: a first node obtains the message; the first node determines a forwarding path of the message when the message needs to be forwarded through a prescribed path; the first node determines at least one output interface according to the forwarding path; and the first node forwards the message to a second node through one of the at least one output interface. According to the embodiments of the invention, when the message is determined to be forwarded through the prescribed path, the forwarding path of the message is determined, the output interface is determined according to the forwarding path, and then the message is forwarded through the output interface, so that message forwarding through the prescribed path is realized in DCN Fabric.
