Initial seed of repo
The following is simply a proposed way of completing the work alagalah@gmail.com has started in the VPP project's repo:
Draw.io doc of simple high level design
The thinking is that this can be used to seed the NSH_SFC git repository, fixing bugs and completing intended PoC SFF / Classifier functionality, as well as kicking off the initial decoupling of VXLAN-GPE/GRE code and NSH code.
From there, we should definitely iterate on the actual design we would like NSH_SFC to have to support all the use cases etc as part of the project scope.
This is NOT intended to be a presumptive final architecture, merely some thoughts on how to achieve completing the PoC and moving the code.
Initial design of NSH-aware SFs
The following is a proposal to enable NSH-aware SFs:
Proposed diagram for enabling NSH aware SFs
Note: The initial design could be treated as NSH Proxy co-locates with the SF, which means the SF can not see NSH. But it will evolve in the future.
