Subject: NEW Issue - DPWS - clarification on accepting unicast Probe

Please defer discussions on this issue until a time this issue is accepted and is assigned a number.

Description:

DPWS now requires (MUST) a device to support receiving a directed Probe over HTTP at any HTTP addresses where the device endpoint is available.

Shouldn't we also define a WELL KNOWN port/uri combination where a device would accept a directed Probe?

This would allow to kickstart a full DPWS conversation knowing only the ip address of the device, as there are many different ways (proprietary, dns, directory based...) to get the ip address of a device.

(this issue is related to issue 27 previously submitted against WS-Discovery)

Proposed Resolution:

Clarify in the specification
