Abstract: This application discloses a service packet forwarding method, an apparatus, and a computer storage medium. In the method, when receiving a packet sent by any second virtual resource module connected to a first SFF, the first SFF dynamically determines a forwarding path of the packet based on configuration information of a second virtual resource module for implementing a second service function, to implement dynamic load balancing on the packet instead of uniformly performing load balancing by a service function chain ingress node, so as to reduce pressure on the service function chain ingress node.
