During PAWS session in Paris IETF, there were a lot of questions/discussions on 'Discovery' of Database. It was not clear to me except if we are talking about "Database Server Discovery", in particular, the domain name or the IP address of the 'Server" that is hosting the database. OTH, I felt that some folks may have different views and they would possibly like to see more features than just discovering the domain name or IP address of the "Database Server".
In some offline discussions, I was told that it may be similar to what LOST (RFC 5222) has defined. I read the LOST protocol and associated architecture and my current understanding is that the LOST use case is different than what we are trying to achieve via PAWS. Here is my understanding of the operating model of PAWS interface (when defined): -"Fixed/Mode II WSD" (per figure 1,<draft-das-paws-protocol-01>) can only query the database -The manufacturer of the "Fixed/Mode II WSD" may be different than owner/operator of this device -"Fixed/Mode II WSD" is certified by the regulatory body of the region that they serve - Either the "Fixed/Mode II WSD" device operator or the device vendor has an a-priori relationship with one or more covering database administrators. This relationship is utilized to either configure or enable the discovery of the proper database to contact in the current location I would like to know the group's view of the above model. To me, finding the emergency services or restaurant information near my location is different than getting to know a server that can provide me with channel/frequency/power and other information in the location where "Fixed/Mode II WSD" is situated. In addition, emergency services do not require a subscription and the service is mandated by the Government/regulatory bodies. Some may argue that 'White Space' service may be free as well, but to my understanding it is not quite the similar model as emergency services. I hope with this thread we can clarify/understand the discovery issue. Regards, _Subir
