 A topology of three devices - **Sampler**, **Sink** and **Broadcaster**. The Sampler sends data to the Sink via the PUSH-PULL pattern. The Broadcaster device sends a message to both Sampler and Sink containing a string "OK" every second. The Broadcaster sends the message via PUB pattern. Both Sampler and Sink, besides doing their PUSH-PULL job, listen via SUB to the Broadcaster.
