Abstract
There is provided a method in which a Service Function Forwarding node (SFF) processes traffic. The SFF determines whether a first Service Function Instant (SFI) is in the state of being able to process traffic. The first SFI is locally connected to the SFF, and implements a Service Function (SF) for the processing of traffic. It is determined whether the first SFI is in the state of being able to process traffic. When the first SFI is in the state of being unable to process traffic, the processing of the traffic is requested from a second SFI in which the same SF has been implemented.
