Hi!

Several years ago I added ipService to our LDAP Database, then I thought it's time to update it. Now I have a conceptual problem: Some services have multiple protocols and port numbers. For example "compressnet".

While it's possible to assign unique names like cn=compressnet@2/tcp,... cn=compressnet@2/tcp,... cn=compressnet@3/tcp,... cn=compressnet@3/udp,...

I wonder how a standard query for "compressnet" should look like. Basically I'd like to leave out the port (@n), but the IANA registry is not unique. I identified these: compressnet mit-ml-dev sql-net rap meter pip csdmbase csdm nmsp uma raid-cd ... optohost004

It seems ipService can have multiple values for ipServiceProtocol, cn, and ipServiceProtocol, but wouldn't that silently assume that all port numbers are valid for all listed protocols? For the example it would be any combination of (UDP,TCP) and (2,3).

To me the only solution seems to force IANA to clean up the mess.

RFC-6335/BCP-165 claims: "Service names are the unique key in the Service Name and Transport Protocol Port Number registry." (page 8)

Opinions?
