    description
        "This module contains the PCEP extensions to base topology model. It
        exposes the LSPs for which a particular node is the head end.

        This module exposes three programming instructions,add-lsp,
        remove-lsp and update-lsp, which map to actively-stateful PCEP
        operations using PCInitiate and PCUpd messages to initiate,
        destroy and udpate LSP configuration. The lifecycle of these
        instructions follows draft-crabbe-pce-pce-initiated-lsp and
        draft-ietf-pce-stateful-pce, completing execution once the head-end
        router has acknowledged operation success. Should the router become
        disconnected, the instruction resolve to Cancelled if the message
        has not been sent into the TCP socket, or Failed it they have.
