This document defines a new connectivity precondition for the Session
Description Protocol (SDP) precondition framework.  A connectivity
precondition can be used to delay session establishment or
modification until media stream connectivity has been successfully
verified.  The method of verification may vary depending on the type
of transport used for the media.  For unreliable datagram transports
such as UDP, verification involves probing the stream with data or
control packets.  For reliable connection-oriented transports such as
TCP, verification can be achieved simply by successful connection
establishment or by probing the connection with data or control
packets, depending on the situation.  [STANDARDS TRACK]
