Interesting. Seems to be not to complex to add, yes. I haven't used pgm yet; I remember the Oracle approach (rdp, IIRC). How is the recovery implemented? I assume the sender buffers the last N datagrams sent, and on request either sends them again if possible or signals "datagram not available". Along these lines? thanks, Joachim _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
