The NorthStar Controller relies on PCEP to instantiate a path between the PCC routers. The Path Computation Element Protocol (PCEP) enables communication between a PCC and the NorthStar Controller to learn about the network and LSP path state and communicate with the PCCs. The PCE entity in the NorthStar Controller calculates paths in the network on behalf of the PCCs, which request path computation services. The PCCs receive and then apply the paths in the network. https://www.juniper.net/documentation/en_US/northstar3.0.0/topics/concept/northstar-controller-overview.html
