Paul, ATS (Address Resolution Service) is based on each node registering a service record in the SM/SA with GID&P_Key=IP address. When you want to map an IP address to IB address it issues an SA query to the SM/SA with an IP that results in GID+P_Key values than can be used by the ULP. ATS is a standard defined by DAT and recently also by ICSC. As I mentioned in the IP to GID API you can specify if to resolve based on the IP infrastructure (like the one Libor described), or based on ATS, or Default (first try IP/ARP, than ATS). And as you mentioned there is value to have the same API for different resolution mechanisms, the SDP code can be altered in future to ride over the proposed API, so it can be used without TCP/IP.
