These extensions empower a PCE to calculate and manage paths specifically for native IP networks, expand PCEP’s capabilities beyond its traditional 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.
