Path Protected Mesh Networks - Modelling the SONET Network in MetaSolv Solution

Hi,

Currently we are modelling all our SONET rings using the standard MetaSolv TM SONET/SDH Template that is packaged with the core product.   All are Physical Rings/Path Switched SNCP.

We now need to introduce Path Protected Mesh Networks into our system and are wondering how others are accomplishing this.  We know other MetaSolv customers must be utilizing PPMN as well.

Is it best accomplished using shared nodes, subtended networks?   In the case where you want to show the entire PPMN on one graphical view, virtual rings?

Any and all input would be greatly appreciated.
