This page demonstrates a possible implementation of the VSBC VNF using the new ONAP DM.

Huawei vSBC CSAR (based on an intermediary version of SOL001)


The ONAP DM provides two techniques to model abstractions - through dangling requirements and abstract nodes, and this page shows how to use each of them:

Model Using Abstract Nodes

Functionally, this model is very similar to the previous solution, with few differences:

  1. the function components HRU, CCU, and VPU are now "wired" to abstract Compute and Storage nodes, and the substitution mapping is now exposing the requirements of these abstract nodes.
  2. (smile) now the model is able to explicitly express sharing of infrastructure between functional components
  3. (sad) some precautions should have been taken in order to mitigate the risk of "capability-like requirements". The host capability of the AbstractCompute nodes and the attached_storage capability of the AbstractStorage node are not mapped through the substitution mapping, even though not all of their occurrences have been spent in the topology
