Abstract Abstract
Service Function Chaining (SFC) is the process of directing packets Service Function Chaining (SFC) is the process of directing packets
through a network so that they can be acted on by an ordered set of through a network so that they can be acted on by an ordered set of
abstract service functions before being delivered to the intended abstract service functions before being delivered to the intended
destination. An architecture for SFC is defined in RFC7665. destination. An architecture for SFC is defined in RFC7665.
The Network Service Header (NSH) can be inserted into packets to The Network Service Header (NSH) can be inserted into packets to
