Hello again

Just to clarify the where from the term "network function" is stemming from:

See https://en.wikipedia.org/wiki/Network_function_virtualization

Note also that within the IRTF there is Network Function Virtualization Research Group, https://irtf.org/nfvrg

Also in the ONF there is  Virtual CPE (vCPE) Framework
https://www.opennetworking.org/products-listing/virtual-cpe-vcpe-framework 



Best regards
Hannu

A more accurate and up-to-date term would be BANANA functions as you may then support virtualized functions that can be located more flexibly e.g. in a host device, or an enterprise could etc.  

It is the explicit intention that “BANANA Boxes” may be separate hardware components or software components running on CPE, an end system, etc.  I will see if i can improve the wording to make this clearer.  We struggled with the right word to use for something that can be a hardware or software component with either proxy-like or tunnel-endpoint-like properties — a word that wouldn’t constrain the solution selection.  I am not familiar with the use of the term “functions” as you describe it, so it doesn’t immediately seem clearer to me.  Does it to others?

Excellent.  This is likely to be the meat of any effort.  The “encapsulations” are expected to use existing protocols like GRE, MPTCP, etc.

Thanks,
Margaret
