Not able to point a classifier to an existing chain

[Dimitrios Markou]

In tacker we cannot create and point a classifier to an existing chain on the fly through tacker API

This is not clear to me. Please describe it in more detail. Thanks

We follow the notion of SFC functionality as it described in the RFC 7665. The main idea in that document is that the classifiers should be independent from the chains which means that we should be able to create chains which has no classifiers or chains in which we can point a existing classifier on the fly.

Thw aforementioned functionality is not supported by the Tacker's VNFFG concept. If I remember correclty (correct me if I am wrong ) we cannot through vnffg to create a chain which has no classifier associated with it or to update somehow the vnffg so we can point another classifier down the road.

Also as I said earlier we don't have the functionality to create only classifiers which has no Chain associated with them through VNFFG.
