The invention relates to an application service message forwarding method and a forwarding node by adopting a multi-protocol label switching (MPLS) technology. The method comprises the following steps that: a forwarding node receives a message; the forwarding node performs the MPLS processing to the received message, wherein when the current node is a Transit in the second hop to last, the original label switching in the message is a virtual label corresponding to a server group; when the current node is an Egress PE, the label in the received message is popped up, wherein the different server groups correspond to the virtual labels of the different server groups; the forwarding node forwards the processed message, wherein the current node is the Egress PE, according to the server group information corresponding to virtual labels of the server groups, the message is forwarded. The method can realize the quick directional forwarding of the content switching.
