Is there a cocoa abstraction for UDP sockets?

Although it is not specified in
file:///Developer/ADC Reference Library/documentation/Cocoa/Reference/Foundation/ObjC_classic/Classes/NSStream.html

I get the impression that
NSStream getStreamsToHost:port:inputStream:outputStream:

is used to create a TCP stream only. The same seems to apply for CFStreams (Core Foundation).

Any suggestions?

The stream classes, as the names suggest, are for stream-oriented sockets. If you wish to use a UDP socket as a run loop source, you can use CFSocket, which is somewhat lower-level but works well enough with Cocoa.
