          Technical Summary
             Relevant content can frequently be found in the abstract
             and/or introduction of the document.  If not, this may be
             an indication that there are deficiencies in the abstract
             or introduction.
 
The document defines an alternative connection model for Message Session
Relay Protocol (MSRP) User Agents (UAs), which uses the
connection-oriended media (COMEDIA) mechanism in order to create the MSRP
transport connection.  The model allows MSRP UAs behind Network Address
Translators (NATs) to negotiate which UA will initiate the establishment
of the TCP connection, in order for MSRP messages to traverse the NAT.
