The Session Description Protocol (SDP) is used to describe the
parameters of media streams used in multimedia sessions.  When a
session requires multiple ports, SDP assumes that these ports have
consecutive numbers.  However, when the session crosses a network
address translation device that also uses port mapping, the ordering
of ports can be destroyed by the translation.  To handle this, we
propose an extension attribute to SDP.

This document is a product of the Multiparty Multimedia Session
Control Working Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
