Hi Linda, That's a good comment. The current interface between an NSF and Switch Controller is misleading. Actually, this links are data channels.
As you said, SFF is usually a switch (as an OVS) in an SDN network. We will modify the figure such that the SFF will be relocated in the box of the SDN network. In our scenario with I2NSF, SDN and SFC, SFF has an NSF-facing interface with Security Controller that asks Security Controller to update an SFP for a traffic flow (needing another security service as an NSF) and then trigger the SFP update SFC Classifier (as another OVS) that puts an SFP for the traffic flow via NSF-facing interface.. We will submit the revised I-D having this figure update and clarification before next Monday. Thanks.
