Service packet forwarding method, apparatus, and computer storage medium

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;

• the first virtual resource module is a virtual resource module for implementing a first service function, and the second virtual resource module is a virtual resource module for implementing a second service function;
• and
• the method comprises:
• receiving, by the first SFF, segment identifier (SID) notification information advertised by any one of the one or more second SFFs, wherein the SID notification information is used to indicate configuration information of a second virtual resource module connected to the any second SFF;
• and
• adding, by the first SFF, the configuration information of the second virtual resource module connected to the any second SFF to configuration information of the second virtual resource module for implementing the second service function;
• wherein the configuration information of the second virtual resource module for implementing the second service function comprises a plurality of entries, the plurality of entries comprises one or more remote entries, and the SID notification information comprises an identifier of the any second SFF and a weight of the second virtual resource module connected to the any second SFF;
• and
• the adding, by the first SFF, the configuration information of the second virtual resource module connected to the any second SFF to configuration information of the second virtual resource module for implementing the second service function comprises:
• creating, by the first SFF based on the SID notification information advertised by the any second SFF, a remote entry corresponding to the any second SFF, wherein the created remote entry comprises the identifier of the any second SFF and the weight of the second virtual resource module connected to the any second SFF.

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 one or more second virtual resource modules;

• the first virtual resource module is a virtual resource module for implementing a first service function, and the second virtual resource module is a virtual resource module for implementing a second service function;
• and
• the first SFF comprises:
• at least one processor;
• and
• one or more memories coupled to the at least one processor and configured to store instructions for execution by the at least one processor, wherein the instructions instruct the at least one processor to cause the first SFF to:
• receive a packet sent by one first virtual resource module connected to the first SFF;
• determine the second service function based on the packet;
• obtain configuration information of the 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
• forward 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.
