To perform Service Function Chaining (SFC) in networks where both MPLS and SPRING (Source Packet Routing in Networking) are enabled, it is required to be able to detect Service Function (SF) connectivity and availability. This document proposes a simple mechanism for SF connectivity and availability detection by using the MPLS echo request and reply messages as defined in [RFC4379].
