    abstract =  {This document describes how Segment Routing (SR) policies can be used to satisfy the requirements for strict bandwidth guarantees, end-to- end recovery and persistent paths within a segment routing network. SR policies satisfying these requirements are called "circuit-style" SR policies (CS-SR policies).},
