Re: [ebxml-msg] Groups - Multi-hop Signal Routing (ebMS-Signal-Routing.doc) uploaded

All,

is it really no option to extend signal message with extra header  
information to give intermediaries the ability to route them? Jacques  
mentions, what I think, two main reasons why these message don't  
contain this kind of information. But I do have two remarks on them:

- I'm not so sure signal messages aren't intended for business  
delivery. The receipt signal for example could have value at the  
business level because it could confirm in a legally valid way that a  
message was received.

- I agree that extra headers would be unnecessary overhead when the  
message exchange is done peer-to-peer, so there's no need for routing  
information. In a multi-hop situation however messages must include  
information which enables intermediaries to route them to their  
destination.
Both the Receipt and Error signal do already contain this information  
by the RefToMessageId attribute. Routing on this field would however  
require each intermediary to have an administration of received  
message ids with their related sender, otherwise the reverse path  
can't be determined. I think we can agree that this isn't a very  
realistic solution. Therefor it seems reasonable to me to extend  
signal messages with header information to make it possible for  
intermediaries to route them to their destination.

Regards
Sander
