> Hi All,

Okay, time to get the ball rolling for service discovery.

I must admit I am not that happy with the draft in its current form.

First reason is the that the draft focuses on announcing router services 
to other routers. This makes it practically necessary to add an over the 
air component to DLEP. I thought we agreed that one of the design goals 
of DLEP was only to communicate between the local radio and the local 
router, exchanging already existing local knowledge.

I think DLEP is the wrong protocol to exchange knowledge between routers 
and I am sure the IETF already has protocols for the two routers 
exchanging service information.

What I had expected in this draft was a way for the radio to announce 
its LOCAL services to the router, e.g. a SIP endpoint to connect your 
routers VOIP network to a locally existing "push to talk" voice channel. 
Other examples would be to announce the existence of HTTP ip/port 
(configuration GUI) or a netconf/ssh port.

The second (minor) issue I have with the draft is the text string used 
to identify the service. It feels a bit "out of place" in all the binary 
encoded data DLEP transfers.
