    abstract =  {In RFC 8957 the concept of MPLS synonymos flow labels (SFL) was introduced. This document describes a simple control protocol that runs over an associated control header to request, withdraw, and extend the lifetime of such labels. It is not the only control protocol that might be used to support SFL, but it has the benefit of being able to be used without modification of the existing MPLS control protocols. The existence of this design is not intended to restrict the ability to enhance an existing MPLS control protocol to add a similar capability.},
