The conflating of the external entity (what the diagram calls endpoint) 
with the ingress / egress is simply confusing and does not match the 
usage the IETF generally uses for those terms.

There are other aspects of this as well, but getting agreement on what 
we want to name, and what their names are, in ways that are consistent 
with general IETF usage, will make it simpler to discuss the other issues.

Yours,
Joel
