Abstract
This application provides a service chain fault protection method, an apparatus, a device, a service chain fault protection system, and a storage medium, and relates to the field of communications technologies. In this application, in an SRV6 static service chain scenario, when a link between an SF network element and an SFF accessed by the SF network element is faulty, a secondary SID is introduced to update a destination address field of a packet header of a packet to the secondary SID, so that the packet is bypassed, based on the secondary SID, to another SFF accessed by the SF network element, thereby implementing fault protection in the link between the SFF and the SF network element.
