RE: [dsdp-tm-dev] initial discovery service
Hi Javier,
 
Service Discovery (or "autodetect") is certainly of interest for us at Wind River, too.
As you might remember from the Toronto meeting, there is a Technology Sub-Group
for Autodetect, but no lead has been assigned yet -- would you want to lead this
effort? - See http://wiki.eclipse.org/index.php/DSDP/TM
 
I think for the actual autodetect, there are a few flavors:
* Autodetect during system definition (in the wizard), assuming that detected services remain the same over time
* Autodetect on each connect, allowing to disable services as needed
 
The actual detection of services could go
* via network (ECF provides some discovery services through Zeroconf),
* it could be through vendor-specific agents running on the remote system,
* or it could be even without asking the live target, e.g. by looking at a local ELF image of the kernel on the target or investigating SPIRIT files.
 
In any case, it looks like the autodetect would basically create a filter that limits a list of
possible subsystems for a given system connection to the list of those that are actually
available; and, for those subsystems that have been found available, perhaps automatically
set some properties.
 
I was not sure how autodetect would relate to a view for hardware actions like restart or reflash?

Cheers,
Martin

Subject: [dsdp-tm-dev] initial discovery service


Hi All,

Symbian couldn't attend the phone meeting yesterday, but we would like to raise a question about the initial discovery of remote embedded systems and how to manage them.
We think it would be interesting having a remote system discovery facility, allowing to retrieve information through a standard protocol such as the description of the system and the list of available services.
Also executing basic hardware services on the remote systems (mainly restart and reflash) could be interesting.

The discovery facility could consist on:

* A contribution to the RSE "New Connection" wizard, at the same position where RSE allows checking if the provided IP exists
* A standard TCP/IP based protocol (to be investigated) to report the available services on the embedded system and start them as requested by the user. At this stage possibly the SPIRIT information could also be retrieved.
* A view to manage registered embedded systems and perform basic hardware actions as restart or reflash.
 
As in the current release only the IP address is checked, possibly an early handshake with the embedded system could be useful.

Is anybody else interested in this feature ?
