This document introduces extensions to the Path Computation Element
Communication Protocol (PCEP) to support path computation in Native
IP networks through a PCE-based central control mechanism known as
Centralized Control Dynamic Routing (CCDR). These extensions empower
a PCE to calculate and manage paths specifically for Native IP
networks, thereby expanding PCEP's capabilities beyond its past use
in MPLS and GMPLS networks. By implementing these extensions, IP
network resources can be utilized more efficiently, facilitating the
deployment of traffic engineering in Native IP environments.
