[RE] Focus of discussions
How far into the detail of the eventual standard are we supposed to go at this stage? As I understand it, the current task is to develop the PAR + 5 criteria in time for the November plenary, the criteria being:
- Broad Market Potential
- Compatibility with the rest of 802.3
- Distinct Identity
- Technical Feasibility
- Economic Feasibility
Will the scope, for instance, include
(a) "ability to convey time-critical data" or
(b) "ability to convey the time-critical data required for [list of applications]" or
(c) something more specific
Do we need to decide at this stage which speeds to support, whether to support jumbo frames [come to think of it, are jumbo frames allowed by 802.3 anyway?], whether to use additional pairs, etc?
Some of these choices could, of course, affect the feasibility (e.g. max size 10 Mbit/s frames are 1.2 msec long so if you're not allowed to fragment them for compatibility reasons you can't have synchronous frames every 125 usec).
