Reliable multicasting

Christoffer Lernö

10/11/2007 7:57:00 PM

Does anyone know if anyone of the reliable multicasting protocols
exist implemented in ruby?

Actually what I am really looking for is something like JGroups
implemented in a language-independent way. I mean jgroups pretty much
seems to need java, and I want to integrate something between, java,
ruby and perhaps PHP.

Anyway I figured that if there at least is a reliable multicasting in
ruby, you could create something JGroups-like on top of that.

Any suggestions would be greatly appreciated.

There is a Ruby interface to the Spread toolkit:

Spread: <http://www.spread.org/SpreadPlatform...
rb_spread: <http://rbspread.sourceforg...

Ah, I should have mentioned I did check out spread, but its not a
canidate due to its need for a separate daemon process.

maybe it can be done - but it seems any reliable multicasting
platform is going to have this requirement - after all someone needs
to be listening on a port(s) to get messages right?

what's the alternative to not having a daemon?

btw - email is a good alternative for some applications - it's pretty
dang reliable ;-)

Well, apparently in JGroups there is no daemon, everything seems to
be handled in each "client" to ensure FIFO, lossless transmission etc.
