Authors and contributors have discussed the use case of abstract topology,
to address the incompleteness of connectivity matrix. 

Current connectivity modeling is as follows:

      |     +--rw connectivity-matrix* [id]
      |     |  +--rw id            uint32
      |     |  +--rw from
      |     |  |  +--rw tp-ref?   leafref
      |     |  +--rw to
      |     |  |  +--rw tp-ref?   leafref
      |     |  +--rw is-allowed?   Boolean

A Link TP may connect or disconnect to another Link TP, without detailed
information such as cost and resource sharing restriction. To get a better
abstraction of such connectivity, the following additional attributes are
planned to be added:

  max-bandwidth?               decimal64
  max-resv-bandwidth?          decimal64
  unreserved-bandwidth* [priority]
  priority     uint8
     +-- bandwidth?   decimal64
     +-- te-default-metric uint32
  performance-metric // re-use the container from te-link-atrributes
  te-srlgs           // re-use the container from te-link-atrributes

Comments are welcome.

Thanks,

- Xufeng
