    abstract =  {This document defines Path Computation Element Communication Protocol (PCEP) extensions to signal multipath information, associating multiple forwarding paths with a single PCEP Label Switched Path (LSP) to allow load balancing and redundancy across diverse paths. The extensions are generic and applicable to both stateless and stateful PCEP and are designed to be reusable for future path types. Their primary application is Segment Routing Policy (SR Policy), where a Candidate Path can contain multiple segment lists: current PCEP extensions for SR Policy only allow signaling of a single segment list per Candidate Path. These extensions enable multipath capabilities such as weighted or equal-cost load balancing across paths.},
