Hi, I have not followed the work on this draft, so I appologize if the following has been discussed. While I do understand that a WS Client has to establish the WebSocket with the Web Server, I don't understand why we need to mandate the WS Server to be an MSRP Relay. That would e.g. prevent the usage of MSRP-CEMA. Regards, Christer Lähettäjä: dispatch [mailto:dispatch-bounces@ietf.org] Puolesta Mary Barnes Lähetetty: 11. tammikuuta 2014 0:59 Vastaanottaja: DISPATCH Kopio: Ben Campbell; draft-pd-dispatch-msrp-websocket@tools.ietf.org Aihe: Re: [dispatch] I-D Action: draft-pd-dispatch-msrp-websocket-03.txt I have agreed to shepherd this document. I've reviewed the document in anticipation of doing the PROTO write-up and have the following comments and questions. Ben Campbell has agreed to do the required expert review and that should be posted within the next week or so. This is also a good time for anyone in the WG that hasn't previously reviewed this document to review and provide any final comments. Note, that this document was agreed to be AD sponsored around the IETF-86 timeframe. Regards, Mary. Review Summary: Almost ready. Comments & questions below. 1) Section 2 & General. I'm not sure the documented approach for separating normative text from non-normative is quite so helpful. In general, we expect that in the case of standards track document use RFC 2119 language to indicate normative behaviors. I think the first sentence is good, but that's not a terminology thing. I just don't see a lot of value in writing the document this way. For example, the definitions aren't stated to be non-normative, but I don't see anything normative about the definitions. I think you could easily title Section 3 as "WebSocket Protocol overview" and that would clearly imply non-normative behavior. There are also several places in the document in sections that I believe are intended to provide normative behavior, but there is certainly non-normative text in those sections (e.g., section 5.2.2, second paragraph). I would suggest this document follow the typical (and accepted) style of identifying normative behavior with 2119 language (consistently using upper case for normative behavior and avoiding using 2119 language in cases where alternative words can be substituted). 2) Section 5.2.2, 2nd paragraph. Related to my point above, it's not clear to me this is normative behavior. I don't think it is since it's referring to existing 4975 behavior. However, I didn't see that the reference given in 4975 relates to the second part of that sentence stating that implementations "should" already be allowing unrecognized transports. It would be quite useful to have the exact reference here as I was trying to double check this point and I couldn't find it. 3) Section 6. I'm really puzzled as to why the Connection Keep-alive would be non-normative. In particular given that 2119 language is clearly being used. 4) Section 7. Again, I'm puzzled as to why Authentication is considered non-normative. AGain, you have 2119 language in this section. 5) Section 10.1. Since securing the connection is just RECOMMENDED, what are the implications and risks if the MSRP traffic isn't transported over a secure connection? 6) Section 11. You should change the name of the registry to be the exact name of the IANA registry to avoid any confusion.- i.e.,: OLD: registry of WebSocket sub-protocols NEW: WebSocket Subprotocol Name Registry 7) Section 11. There is also a Reference field in that IANA registry. I would suggest you use the same information as the pointer to the Subprotocol Definition (i.e., this RFC). 8) It's typical for documents that are updating existing RFCs to have a section that summarizes the updates to the existing RFCs that are made by this document.
