    abstract =  {This document presents the basic network objectives for the behavior of shared mesh protection (SMP) not based on control-plane support. This is an expansion of the basic requirements presented in {[}RFC5654{]} "Requirements for the Transport Profile of MPLS" and {[}RFC6372{]} "MPLS- TP Survivability Framework". This document is to be used as a basis for the definition of any mechanism that would be used to implement SMP for MPLS-TP data paths, in networks that delegate executive action for resiliency to the data plane.},
