Vnf failover method and apparatus

A virtualized network function (VNF) failover apparatus, comprising:

• a processor;
• and a non-transitory computer readable storage medium storing a program for execution by the processor, the program comprising instructions for:
• receiving a fault message, wherein the fault message indicates a first VNF is faulty;
• determining a primary affinity group to which the first VNF belongs and a secondary affinity group corresponding to the primary affinity group, wherein VNFs in the secondary affinity group are in a one-to-one correspondence with VNFs in the primary affinity group, and the affinity group represents a set of VNFs on which an affinity policy is used;
• and
• instructing the VNFs in the secondary affinity group to continue to process services of the VNFs in the primary affinity group.
