Hi Harald, 

 

Sec 3 & 4 of the draft deals with the need and advantages for standard
signaling protocol. I understand your major concern is time. I think
through and provided some solution as part of the draft

 

1)      Sec 5:  (RTCWeb Protocol requirement and design consideration)
is added to come up with the thump rules for standard signaling rather
than discussion different protocol

2)      Sec 6:  The list of existing signaling protocol is shown for
eliminating the signaling protocol based on Sec 5 conclusion

 

In case time factor to solve this issue is the reason for rejecting this
proposal , let us work for the better way to reduce the timeframe to
achieve the result. 

 

Thanks

Partha

Ravindran,

the core part of your document seems to me to be this list:




   The following Signaling protocols will qualify for becoming standard
   RTCWeb signaling protocol
 
   1.  Jingle
   2.  Websocket with SDP offer/answer
   3.  SIP
   4.  SIPLite [I-D.cbran-rtcweb-protocols
<http://tools.ietf.org/html/draft-partha-rtcweb-signaling-00#ref-I-D.cbr
an-rtcweb-protocols> ]
   5.  Websocket with custom XML
   6.  Megaco [RFC5125 <http://tools.ietf.org/html/rfc5125> ]
   7.  Websocket with SIP [I-D.ibc-rtcweb-sip-websocket
<http://tools.ietf.org/html/draft-partha-rtcweb-signaling-00#ref-I-D.ibc
-rtcweb-sip-websocket> ]
   8.  HTTP with custom XML
   9.  ???
 
   TBD: Pros and cons for each of the signaling mechanism has to be
   added


My reading of your document is that you want the RTCWEB working group to
pick exactly one of these alternatives, and insist that all conformant
implementations of RTCWEB support this protocol.

I disagree with:

a) that this is needed
b) that this is a good idea

The reasons why it is not a good idea have been raised multiple times,
and spending continued effort on trying to debate which of the
alternatives you list above is "the best one" is distracting to our
purpose of getting the RTCWEB protocol suite done.

I do not support pursuing your suggested direction of work in this
working group.

                     Harald

Hi all,
 
RTCWeb standard signaling protocol
(http://tools.ietf.org/html/draft-partha-rtcweb-signaling-00) draft list
the need for standard signaling protocol between RTCWeb client (browser)
and RTCWeb server and the possible signaling protocol for the same. This
draft is written based on
http://www.ietf.org/mail-archive/web/rtcweb/current/msg01172.html mail
thread discussion. Could you please provide your valuable comments.
 
Thanks

repository.
 
Filename:      draft-partha-rtcweb-signaling
Revision:      00
Title:         RTCWeb standard signaling protocol
Creation date:  2011-10-03
WG ID:         Individual Submission
Number of pages: 8
 
Abstract:
   The standardization of Real time communication between browsers is to
   provide the infrastructure for audio, video, text communication using
   standard interface so that interoperable communication can be
   established between any compatible browsers.  RTCWeb specific
   Javascript API will be provided by browsers for developing real-time
   web application.  It is possible to develop signaling protocol like
   Session Initiation Protocol (SIP) or Jingle or websocket extension or
   custom-made signaling protocol in Javascript.  There are lots of
   issues in Javascript based signaling protocol.  This document list
   the need for standard signaling protocol between RTCWeb client
   (browser) and RTCWeb server and possible signaling protocol for the
   same.
