Technical Summary

This document lists the different mechanisms that enable applications
using Real-time Transport Protocol (RTP) to maintain their RTP
Network Address Translator (NAT) mappings alive. It also makes a
recommendation for a preferred mechanism. This document is not
applicable to Interactive Connectivity Establishment (ICE) agents.


Working Group Summary

This document began in 2006 as a proposed BEHAVE work item with
broader scope. The scope was refined after discussion between
BEHAVE, MMUSIC, and AVT Working Groups to that indicated above.
The rtp-keepalive SDP parameter was added by direction of the
AVT Chair when no comments were received either for or against
that proposal.


Document Quality

This document was shaped by comments from a number of contributors,
as listed in the Acknowledgments section. As a general application
guide, it is expected to have broad implementation.
