Zusammenfassung:A method and system of performing service function chaining is disclosed. The method includes: determining a service function path (SFP) for a packet transmitted to the network device; determining a service function (SF) through which the received packet passes on the SFP; and processing the received packet based on whether a function of the SF is essential or not. Accordingly, the SFs can be categorized into mandatory SFs and optional SFs based on the functions of the SFs or the setting for the SFC and the SFC can be more stably implemented based on the categorization.
