    abstract =  {This document proposes an extension to BGP-LS that allows a headend node, when reporting SR Policy state information via BGP-LS, to carry a new state flag at the candidate path level. This flag indicates whether the candidate path is currently being used for packet spraying. The information can be consumed by external controllers for path optimization, operations management or other purposes.},
