<DIV><FONT size=2>Hi, </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Can anyone give an answer to my question?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1. SIP will be the signaling protocol for IMS in
3GPP,and SIP can be over TCP, UDP, or SCTP;</FONT></DIV>
<DIV><FONT size=2>2. For SIP over TCP as signaling transfer, are there
any analysis model for the performance evaluation?</FONT></DIV>
<DIV><FONT size=2>3. Somebody told me that there is no problem if
you allocate enough bandwidth to signaling channel.</FONT></DIV>
<DIV><FONT size=2> (the enough bandwidth in engineering design may
be 10% of total transmission line capacity)</FONT> </DIV>
<DIV><FONT size=2> So, is there any measured data to support the
above design.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>4. Could you get better performance by SIP over SCTP than SIP
over TCP for signaling transfer?</FONT></DIV>
