[Twisted-Python] Question about PB and multicast
I am building an application that has tens of thousands of clients. There are times when I need to talk to quite a few of the clients using PB. When I have to talk to a single (or a few) clients via PB I do the normal thing - issue multiple calls. In the cases where I have to talk to quite a few clients I had thought of changing the object I am sending to include the names of the machines I am interested in talking to. I would then send it via multicast using PB. I know this would require some changes on the PB side, but I am wondering if anyone sees a problem doing this? Peace, Chaz.

PB connections were only ever designed to operate between two peers. It's designed to run over a reliable stream protocol, e.g. TCP. TCP doesn't work over Multicast (it doesn't make any sense, if you think about it). If you want to use Multicast, I think you'll pretty much have to write your own thing using UDP. -Eric

Actually, PB's initial design did include provisions for operation over UDP. However, Twisted does not include any implementation of those parts of PB, so this is perhaps a useless correction. ;) Jean-Paul
