The de facto Internet architecture is very different from what was envisioned when it's core
semantics were designed. While still end-to-end in many ways, connection establishment in the
Internet today involves state and functionality in the middle in the form of NATs, firewalls,
proxies and so on. The accepted Internet architecture does not reflect this resulting in a
mismatch between design and practice. This IRTF group aims to explore the problem-space
presented by today's Internet and come up with a new Internet architecture that incorporates
both the end and the middle.
In an attempt to map out the problem space, some point-solutions are presented that demonstrate
how one might establish connections in a future Internet.
Signaling based solutions to connection establishment
NUTSS primarily relies on off-path signaling
CSP primarily relies on on-path signaling
This document presents a high-level design for an End-Middle-End
(EME) signaling protocol called NUTSS (which stands for NAT, URI,
Tunnel, Signaling, STUN). While high-level, this document tries to
be detailed enough that the EME RG can have a meaningful debate about
its pros and cons and possible alternatives. The main attribute of
NUTSS is that it couples together both path-coupled and path-
