Segment routing (SR) leverages the source routing and tunneling paradigms. The Stateful PCEP extensions allow stateful control of Segment Routing Traffic Engineering (TE) Paths. Furthermore, PCEP can be used for computing SR TE paths in the network. This document defines PCEP extensions for optimizing the arrangement of segment lists to solve the problem of the penultimate segment node being unable to perform PSP behavior when the egress node has both End SID and service SID, and improve the forwarding efficiency of data packets.}, }
