Returning just one single traffic path does not provide a valid solution. This document defines mechanisms to encode multiple paths for a single set of objectives and constraints. This allows encoding of multiple Segment Lists per Candidate Path within a Segment Routing Policy. The new PCEP mechanisms are meant to be generic, where possible, to allow for future re-use outside of SR Policy. The new PCEP mechanisms are applicable to both stateless and stateful PCEP.}, }
