I was involved, the other day, in a lively discussion on how we could use our X.500 directory systems to look up presentation addresses for various services and hosts. I'm not talking about a small number of machines, but potentially thousands. The questions boiled down to: "How do you name a host and service in the OSI world (akin to a DNS hostname and a TCP/UDP service name/port)?", and given that you have such a name, "what is the best way to use X.500 to retrieve the corresponding presentation address?" Has anyone given thought to how this should be done? I'm aware that the ISODE contains an implementation of DASE which allows one to look up a presentation address given a user-friendly name (UFN) and an application context. However, if, for example, I wanted to put all of the machines at NASA Ames Research Center into the directory and use DASE to do lookups, I would end up with a few thousand additional entries under the DIT location US, NASA, ARC. This is where my people entries are. And this is where one might logically expect to find my machine entries. Clumping them together, though, means that search performance for both people lookups and service lookups goes down. And if I'm not using DASE, I've no idea where I might need to search (particularly since there is no standardized naming scheme for OSI end-systems). Well, has anyone got some ideas on this one. I'd love to hear them. Anything. My thanks in advance. -Peter Yee yee@atlas.arc.nasa.gov
