It's pretty straightforward. The upmost component uses a single ZMQ_DOWNSTREAM socket to send messages. All the components in the middle of the chain use one ZMQ_UPSTREAM socket to get messages and one ZMQ_DOWNSTREAM socket to send them further. The last component in the chain uses single ZMQ_UPSTREAM socket to get the results.
