Network Address Translation (NAT) Behavioral Requirements for Unicast UDP
Abstract
This document defines basic terminology for describing different types of Network Address Translation (NAT) behavior when handling Unicast UDP and also defines a set of requirements that would allow many applications, such as multimedia communications or online gaming, to work consistently.Developing NATs that meet this set of requirements will greatly increase the likelihood that these applications will function properly.

Two conflicting trends have emerged since Halkes et al.'s study: (i) expected reduction in EDM NAT deployment as vendors comply with BEHAVE RFC, and (ii) proliferation of Carrier-Grade NAT (CGNAT) deployments, which employed EDM translation in 40% of cases as of 2016.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
