[conex] Abstract marking and encoding in IPv6

[Ingemar Johansson S <[e-mail]>]

Hi

Given yesterdays presentation on the abtract encoding mechanism and the IPv6 encoding options my findings are:

+ Encoding in IPv6: To me it seems like the only way to make ConEx commercially attactive is to use some of the bits from the flow label field. It was to me pretty clear that extension headers (including the hop-by-hop options header) are not very useful in this context and it was also explained (Rich Woundy) that the latter are not even useful for experimentation (my interpretation). So what is required here is to convince 6man (and others) that ConEx is a good use case for N bits in the flow label field reserved for ConEx.

+ Encoding of abstract mechanism: Now that I (believe I) understand the green marking (and the necessity of it) it is to me quite obvious that 5 codepoints are needed, thus 3 bits are needed, this leaves 1 unused codepoint waiting for an interesting use case...
