[6lowapp] BOF proposal: update

[[e-mail]]

Hi Carsten and al,

I have a few remarks/suggestions to complement the BOF proposal.
I would like to emphasize on the need for seamless integration of 
up-and-coming architectures and Web Services.

In the world of wireline embedded solution, the Device Profile for Web 
Services (DPWS) is now a recognized OASIS standard to provide low cost 
SOA solution at the device level, providing a complete solution both at 
the application protocol level and at the commissioning level.
In the wireless world, the DPWS solution can be used in conjunction with 
Binary XML encoding solutions such as EXI.

expanded)
...but does not exclude considering standardized binary XML solutions to 
compress messages.

Eventing is also important, e.g. WS-eventing (as provided by DPWS) using 
SOAP over UDP and Binary XML encoding.

Proposal:
   -- Proxying with HTTP, SNMP and WS-Management must be straightforward.

SNMP, despite a large installed based will likely decline in new 
architectures and will be replaced by new protocols like WS-Management. 
Seamless integration of WS-Management must be considered.

Proposal:
     -- Proxying with IP service discovery protocols such as SLP, SSDP or
     DNS-SD or WS-Discovery as provided by DPWS must be straightforward.

Looking forward for your feedback.
