[zeromq-dev] Request-Reply Pattern

Suppose a command is sent to several receivers, some of them will perform some tasks and then send the result back the sender.
So, the connection between sender and each receiver is required. However, I don't want to create too many connection and the number of receiver may be increased. Is is possible to use one connection to publish the command and serve the purpose as above?

Sorry, it is not true that DEALER/ROUTER are used to broadcast requests. 

Please describe your purpose so that we can propose the proper solution. Also, please read the zguide.zeromq.org and focus on chapters 2, 3, 4 and 5. Those chapters describe the patterns and how to use them for both simple and advanced techniques.
