        Title           : Stream Control Transmission Protocol (SCTP) Network Address Translation Support

   The Stream Control Transmission Protocol (SCTP) provides a reliable
   communications channel between two end-hosts in many ways similar to
   the Transmission Control Protocol (TCP).  With the widespread
   deployment of Network Address Translators (NAT), specialized code has
   been added to NAT for TCP that allows multiple hosts to reside behind
   a NAT and yet share a single IPv4 address, even when two hosts
   (behind a NAT) choose the same port numbers for their connection.
   This additional code is sometimes classified as Network Address and
   Port Translation (NAPT).

   This document describes the protocol extensions required for the SCTP
   endpoints and the mechanisms for NAT devices necessary to provide
   similar features of NAPT in the single point and multi point
   traversal scenario.

   Finally, a YANG module for SCTP NAT is defined.
