Subject: Re: [amqp-bindmap] Groups - Advanced Message Queuing Protocol (AMQP) WebSocket Binding (WSB) Version 1.0 WD03 uploaded


Hi David,

I finally managed to review the latest version of the WebSocket Binding
specification... I have only some minor comments ...

1) The diagram in the introduction chapter 1 looks a bit incomplete. The
text talks about AMQP message -> AMQP Frame -> WS Message -> WS frame
hierarchy, but the diagram shows only AMQP Frame -> WS Frame relation.
Would extending the diagram make the introduction too complicated? Or do we
want to include a complete diagram bellow? The same would apply also to the
chapter 4.2.

[ AMQP Message 1 of 1]
|                     \_________
|                               \__________
|                                          \
[ AMQP frame 1 of 2 ]   [ AMQP frame 2 of 2 ]
|                   |   |                   |
|                   |   |                   |
[ WS message 1 of 2 ]   [ WS message 1 of 2 ]
|                   |   |                    \________
|                   |   |                             \________
|                   |   |                                      \
[  WS frame  1 of 3 ]   [ WS frame 2 of 3 ]   [ WS frame 3 of 3 ]

2) The diagram in 2.3 refers to the figure 3 (F3) for the "OPEN" step. But
bellow are only figures 1 and 2. Figure 3 is only in the chapter 3.4 and
shows the "HTTP GET" step for the diagram with SASL authentication.

3) The example in chapter 3.4 is in the diagram referring to the figures 3
and 4 as F3 and F4. I seem to be always confused by it, because at a first
look it makes me feel that we are missing the first two steps of the
diagram (as in 1, 2, 3, 4). Can we make a bit more clear that it is a
reference to the figures bellow? Maybe like this?

WS Client  			    WS Service
/ AMQP Endpoint               / AMQP Endpoint
  |                                |
  | HTTP GET (WS handshake)        |
  |                 see Figure 3)  |
  |------------------------------->|
  | 101 Switching Protocols        |
  |                (see Figure 4)  |
  |<-------------------------------|

4) Chapter 5.1 and chapter 5.2 look a bit strange, because the first and
third paragraph are always the same. I assume the first paragraph is for
AMQP without SASL while the third for AMQP with SASL?

Thanks & Regards
Jakub
