John, you don't exactly have what I'm proposing. Consider the following two independent ws connections connection 1: op=text data=Hello World op=binary data=9ab39129def329432993 op=test data=goodbye connection 2: op=text data=One op=binary data=2222222222222 op=text data=three A hypothetical MUX extension might merge those connections as: op=extended ext=MUX(channel=1,type=text) data=Hello World op=extended ext=MUX(channel=2,type=text) data=One op=extended ext=MUX(channel=1,type=binary) data=9ab39129def329432993 op=extended ext=MUX(channel=2,type=binary) data=2222222222222 op=extended ext=MUX(channel=2,type=text) data=three op=extended ext=MUX(channel=1,type=text) data=goodbye On 17 August 2010 00:51, John Tamplin <jat@google.com> wrote: > Maybe a compromise would be to define an opcode EXTENDED_FRAME, and for that > opcode the n bytes (however many we want to allocate) are an extension ID, > and the rest are extension-defined (which might include data from multiple > logical channels, for example, so it would need multiple frame > types/lengths). that's more or less what I'm proposing. Although I think of it more as using something similar to Ian Fette's proposal for extension data, but only for 1 op code. > Also note that you were previously suggesting moving the message length > field to the extension data -- that wouldn't be possible if we do away with > extension data and instead make it an opcode. So, I assume that means we > would keep the message length as defined in the current proposal. It could still be done as an extension. Eg the message op=text data=Hello World might be fragmented as op=text frag=1 data=Hello op=text frag=0 data= World If you wanted to send the message length, you might send op=extension frag=1 ext=META-DATA(byte-length=11, char-length=11, content-type=text/plain) data=Hello op=text frag=0 data= World Or if you wanted to preserve the ability of intermediaries to see the data you could send: op=extension frag=1 ext=META-DATA(byte-length=11, char-length=11, content-type=text/plain) op=text frag=1 data=Hello op=text frag=0 data= World Or if you wanted to hide the data from intermediaries that didn't know the extension op=extension frag=1 ext=META-DATA(byte-length=11, char-length=11, content-type=text/plain) data=Hello op=extension frag=0 ext= data= World cheers
