Hi Mark,
Thanks for your feedback, and I think there are some issues that I
need to clarify.
we have to be clear that the discovery mechanism is provided as an
optional method that can help master device to find the correct WSDB, which
means the master device can get WSDB by, such as, pre-configuring of WSDB,
provision etc.
The dynamic discovery mechanism provides more convenient for master
device to find WSDB, for example, when a new WSDB is setup for providing
service or when some deployed WSDB goes down and never work.
About the DHCP you mentioned below, technically speaking, there have
been some extension of DHCP for supporting the provision of LoST server, refer
to RFC5223. Besides, using DHCP method doesn't means IP network provider must
have some business relationship with WSDB DS provider, if the network provider
wants to provide master device with FQDN of WSDB DS it can use DHCP.
Best Regards,
Xinpeng.

Hi Xinpeng,
In section 3, you state:
The URL or IP address of WSDB DS can be found by any method such as
DNS, DHCP, manually configuring etc, and it is out of scope of this
document.
I'm unclear on how the Master device obtains the URL of a trusted discovery
server unless there is some pre-configuration involved. I understand that DNS
could be used if the Master device is already pre-configured with a
preferred/home TVWS DS URL (or a preferred/home domain that is then resolved
with U-NAPTR) but I don't see how DHCP could be used to bootstrap this
information in the TVWS scenarios. Please could you elaborate.
Thanks
Mark
