Technical Summary

This document defines a set of extensions needed to the stateful Path
Computation Element (PCE) communication Protocol (PCEP), so as to

and LSP setup/deletion based on the actual network resource usage and
the duration of a traffic service in a centralized network
environment as stated in RFC 8413.
