Hopping along

Here is a first cut 
at a multihop section outline. If I dont hear outcries I'll start to flesh out a 
draft along these lines, based on what we have heard so far.

Multihop Messaging 

 

1.1 
Multihop Topologies

·         
Hub-and-Spoke

·         
Interconnected Hubs

·         
Bridged Domains (with interconnected 
Gateways)

 

1.2 
Usage Requirements

·         
Connectivity and Addressability 
constraints (MEPs supported, private IP domains…)

·         
QoS of exchanges (end-to-end RM,  signature over all headers, WS-I 
compliance, transparent intermediary and streaming…)

·         
Intermediary Configurability and Change 
management (PMode [non]awareness, routing functions and their 
updates…)

·         
Contingent requirements (possibility of 
user message bundling,…)

·         
Endpoints requirements ([non]awareness of 
the I-Cloud, V3 conformance level, WS-addressing support)

·         
Error handling

 

1.3 
The Intermediary MSH Role

·         
Message forwarding (requirements for 
Intermediary, MPC handling, MEP bridging) 

·         
Routing function: Header metadata used, 
Reverse routing (or eb responses, of eb signals)

·         
Use of WS-addressing EPRs

·         
Error handling

 

1.4 
Reliable Multihop

·         
Establishing a Reliable Sequence with 
WS-ReliableMessaging (requirements on Endpoint MSHs…)

·         
Routing of response RM signals (use of 
WS-a headers, ref parameters…)

·         
Case of non-addressable 
endpoints

·         
The case of WS-Reliability conformance
