Bob -- If it's OK with you I'm taking the conversation public again, for the time being anyway.

We're a ways away from being able to give a name like Radio Services Architecture, yet, I think. For a number of reasons, I propose we begin with what I'll call the Radio Space. This seem like an appropriate term? It's metaphorically suggestive. It's also the right concept formally, too, I believe, since an SDR "application" will turn out in the end to be, precisely, a topology on the Radio Space. The points in the Radio Space are the functional nodes we've been talking about -- the DSP, the hardware control, the audio subsystem, pieces of the UI, etc. We will probably find it useful to flip-flop back and forth as convenient between thinking of these components as points or as nodes, with the Space and the topology being either point sets or graphs. So where we start is with a bunch of nodes but no edges connecting the nodes. There's no hierarchy or layering yet, merely a bunch of functional components that can be made to pass messages among one another. > Services are composeable, that is they can be orchestrated to produce a > working application. Yes. In these terms, a compositional grouping of components amounts to inducing a coarser topology on the Radio Space. In practical terms, it amounts to having a way to wrap them together so as to be able to deal with them as if they were a single functional unit. All right so far? 73 Frank AB2KT _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
