The NP Managed Structure
The NP model is built of Application, Transport Entity (TE) and Path Elements.
The Application is a container of TEs. It contains at least one TE.
The TE can be:
− circuit,
− trail,
− Sub Network Circuit (SNC),
− unknown.
The TE has a Path, which connects the endpoints: a End TP (Terminating Point) with z End TP. The path elements can be a:
− Sub Network Connection (SNC),
− Link Connection (LC),
− Matrix Connection (MC),
− Hole.
The diagram below illustrates the relationship of TEs and Path elements.
