1. A service packet forwarding method, applied to a first service function forwarder (SFF) in a communications network, wherein the first SFF is connected to one or more first virtual resource modules, the communications network further comprises one or more second SFFs, and each second SFF is connected to one or more second virtual resource modules, and the first SFF is also connected to the one or more second virtual resource modules; each of the one or more first virtual resource module is a virtual resource module for implementing a first service function, and each of the one or more second virtual resource module is a virtual resource module for implementing a second service function
the method comprising:
receiving, by the first SFF, a packet sent by one first virtual resource module connected to the first SFF;
determining, by the first SFF, the second service function based on the packet;
obtaining, by the first SFF, configuration information of one second virtual resource module for implementing the second service function, wherein the configuration information of the second virtual resource module comprises an identifier of each of the one or more second SFFs, and a weight of a second virtual resource module connected to each second SFF; and
forwarding, by the first SFF based on the configuration information of the second virtual resource module, the packet to one second virtual resource module connected to the first SFF or one of the one or more second SFFs.
