Even that won't guarantee delivery :-) What if your acknowledgment gets lost? Plus it adds extraordinary latency to traffic. Depending on your application, you would want some kind of asynchronous negative acknowledgment, i.e. "I'm missing data X, please (re)send". Possibly out of band so the normal pubsub traffic can scale to many clients over multicast. It gets complex. We're looking at this in Ch4 but really it's a project by itself. -Pieter _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
