Hi Toshi & Karl, I am about to re-draw the slides of Toshi for inclusion in a document that presents the ideas of the three presentations given in the second and third GRAAP session. I will also try to re-draw slide 7 taking into account the discussion on the list and then sent it to the list again to see whether I understood Toshi, Karl and the ongoing discussion ;-) Best regards Wolfgang Toshiyuki Nakata schrieb/wrote:
Hi Again:
I wouldn't say slide 7 captures my comment. My endpoint rendering doesn't imply a third entity, just that the responder entity is rendered with multiple endpoints to allow a more general scenario such as renegotiation that could combine multiple agreements (something you couldn't do if the preceding agreement is always implied like the "this" pointer in a simple object system):
1. agreement initiator sends offer to agreement factory
2. agreement factory sends accept (sync or async reply)
... repeat 1-2 for multiple agreements...
3. renegotiation initiator sends offer to agreement factory
4. agreement factory sends accept (sync or async reply)
These are somethngs I can guess and feel provide an elegant solution, but I feel that the implicit messages needed here between the Agreement Responder and the Agreement Factory would needed to be spelt out or (My guess) would always, fail..
#Karl please tell me that I'm wrong...
So for the moment, I personally feel that a more simple protocol either using PendingXXX would be better..
#Your thoughts everyone :-) Best Regards Toshi @ safely moved from freezing East Coast US to a warmer Silicon Valley
