Is there any way to have an asynchronous client and server in ZeroMQ?

Is there any way to have an asynchronous client and server in ZeroMQ, using the same TCP-port and many sockets?

I already tried the ROUTER/ROUTER pattern, but with no luck.

The plan is to have an asymmetric connection with send and receive patterns among processors. So a Processor-entity will be a Client and also be a Server at the same time.

Yes, there is.

As a preventive step, in other words, before getting into troubles, best review the main conceptual differences in [ ZeroMQ hierarchy in less than a five seconds ] or other posts and discussions here.

The Yes above means, one-.bind()-many-.connect()-s, which composition still uses a just one <transport-class>://<a-class-specific-address>, that for a tcp:// transport-class on IPv4 means that one tcp://A.B.C.D:port# occupied for this whole 1:MANY-sockets-composition.

For obvious reasons, more complex compositions, like many-.bind()-s-many-.connect()-s, are possible, where feasible, given both the ZeroMQ infrastructure topology options and also socket-"in-band"-message-routing features are thus setup and used for smart-decisions on actual message-flow mechanics.
