Title : UDP Encapsulation of SCTP Packets for End-Host to End-Host Communication
Author(s) : Michael Tuexen

Abstract:
This document describes a simple method of encapsulating SCTP Packets
into UDP packets and its limitations. This allows the usage of SCTP
in networks with legacy NAT not supporting SCTP. It can also be used
to implement SCTP on hosts without directly accessing the IP-layer,
for example implementing it as part of the application without
requiring special privileges.
Please note that this document does not provide all techniques
necessary for building a complete NAT-capable application using SCTP.
This document focuses on the functionality required within the SCTP
stack and making this available via an API. It does not cover
mechanism to determine whether UDP encapsulation is required to reach
the peer and, if UDP encapsulation is used, which remote UDP port
number can be used.
This document covers only end-hosts and not tunneling (egress or
ingress) end-points.
