Summary: The document is on track for publication as an Informational 


RFC, but has some issues that should be addressed before publication.




Major issues: none

Minor issues:



- Please expand acronyms at first usage. In particular, I didn't find a 


description of what "IM" is. Are you referring to Instant Messaging?






- Continuing with the previous one, now on Section 6.13. If you refer to 


Instant Messaging, then it is not clear to to me if you are benchmarking 


the one-shot Instant Message produced by the SIP MESSAGE method or if you 


are benchmarking the session-based Instant Messaging created with SIP and 


instantiated with MSRP. Please clarify what you are benchmarking and 


please add a reference to an RFC that defines the IM that you are 


benchmarking.






Nits/editorial comments:



- General: to avoid confusion, the text should add reference to other 


protocols when they are mentioned in the text. This includes: RTP, SRTP, 


perhaps event TCP and UDP, although these two should be clear for everyone.




- Section 4.1 The text says:

   Test cases may be performed with any transport protocol supported by
   SIP.  This includes, but is not limited to, SIP TCP, SIP UDP, and
   TLS.



  My comment: SIP TCP and SIP UDP are not transport protocols. TCP and 


UDP are transport protocols.





- Section 4.4. The text says:

   The test cases specified in this document provide SIP performance
   independent of the protocol used for the media stream.  Any media
   protocol supported by SIP may be used.  This includes, but is not
   limited to, RTP, RTSP, and SRTP...




  My comment: As far as I know, RTSP, specified in RFC 2326. is NOT a 


media protocol, and SIP is not intended to establish RTSP sessions.
