Description

Draft of the multi-hop section.
V0.3:
- a few updates in the definition section (editorial)
- added a commented Flow diagram (section 1.7.1) on RM sequence establishment. To review.
V0.4:
- section 1.5 (Intermediary Role) rewritten, though not complete yet.
(diff with 0.3 visible)
V0,5:
- section 1.5 updated based on feedback and extended for response messages.
V0.14:
- Section 1.5 redefines multihop MEPs in terms of first hop + last hop. It does not include the routing inside the I-Cloud which is relevant to the routing function.
- Section 1.5.4: Two options for multi-hop pulling ... and probably one too many.... Need to define multihop pulling.
- Section 1.6.3 on routing function has been edited.
- Section 1.8 on PModes has been deeply redesigned based on what was said prior

V0.6:
- Added text to section 1.5 on streaming and store-and-forward models for implementing intermediaries
V0.7:
- Changed the text describing the streaming model to include two sub cases, asynchronous and synchronous streaming.
V0.8:
- a few updates / corrections (diffs visible)
- fleshed out the "routing of Acks" multihop subsection at the end.
V0.9:
- Updated definition of routing function and mep bridging
- Changes to section on details of the routing function. The changes here are mostly textual. Changes shouldn't have impact on spec itself.
V0.10:
- Moved section 1.4.3 Endpoints requirements to 1.6 where requirements can be more explicitly formulated
- Reformatted handling of routing input by intermediary
- New section 1.6 on Endpoints requirements, includes introduction of RefParam PMode feature
- Added section 1.7 to specify definition of WS-A reference parameter
V0.11:
- Added text to section 1.4.6 on specific MEP bindings for multi-hop
V0.12:
- added missing flow diagrams (not yet fully comented)
- inserted text for Section 1.8.
- added several comments ([jacques]) and complement text (diffs visible)
V0.13:
- more complete draft of the MEP section 1.5, with multihop channel bindings.
- added a new section on PModes for multihop (1.8)
- minor changes in 1.7
- expanded on the Error handling section (1.4.5)
V0.15:
- Section 1.5 redefines multihop MEPs in terms of first hop + last hop. It does not include the routing inside the I-Cloud which is relevant to the routing function.
- Section 1.5.4: Two options for multi-hop pulling ... and probably one too many.... Need to define multihop pulling.
- Section 1.6.3 on routing function has been edited.
- Section 1.8 on PModes has been deeply redesigned based on what was said prior
V0.16:
- more complete section 1.8
- figures added in MEP section, explicit model separating ICloud hops from "peripheral hops".
V0.17:
- sharpening of terminology in earlier sections
- Section 1.5 largely rewritten, with updated figures (for terminology)
- still some clean-up to do in 1.5 and also 1.8
V0.18:
- remodeling of section 1.5, especially 1.5.2 and 1.5.3, with missing cases and new figures.
- some figures migrated from 1.5 to 1.6
-section 1.7 on endpoint requirements, reorganized, with an addition on how to interpret wsa:ReplyTo (1.7.3).
- edits in 1.8, with main addition 1.8.3 on how to control other aspects of multihop edges binding (not complete yet)
V0.19:

V0.20:
- Added a more complete WS-Addressing section (1.7.1)
