Abstract:
Disclosed are an SFC-based packet forwarding method, device and system, capable of implementing the redirection of a packet forwarding path by means of automatic configuration of a control node for a service function forwarding node. The packet forwarding method comprises: a first service function forwarding node receives a packet forwarding rule sent by a control node, the packet forwarding rule being used for indicating a mapping relationship between matches of traffic characteristic information and routing prefix information; the first service function forwarding node receives a first packet, a packet header of the first packet carrying traffic characteristic information of the first packet; the first service function forwarding node determines, according to the packet forwarding rule, target routing prefix information corresponding to the traffic characteristic information of the first packet; the first service function forwarding node determines target next hop information according to the target routing prefix information, and forwards the first packet according to the target next hop information.
