    abstract =  {This document presents the basic network objectives for the behavior of Shared Mesh Protection (SMP) that are not based on control-plane support. This document provides an expansion of the basic requirements presented in RFC 5654 ("Requirements of an MPLS Transport Profile") and RFC 6372 ("MPLS Transport Profile (MPLS-TP) Survivability Framework"). This document provides requirements for any mechanism that would be used to implement SMP for MPLS-TP data paths, in networks that delegate protection switch coordination to the data plane.},
