I think you can also have an out of band pub-sub over TCP to send acks from clients to server. You need some way to count acks (e.g. clients may send presence notification before start of a transfer). But it may give you a way to limit bandwidth in more automatic way. You may also look at ZMQ_RATE and ZMQ_RECOVER_IVL options, they should (theoretically) give you reliability without out of band socket to request data, however I don't know how well that works in practice. -- Paul _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
