title: Topics in ZeroMQ
body: <p>How better to separate topics using ZeroMQ - just by specifying different ports or by using prefixes like here: <a href="https://stackoverflow.com/questions/13904626/zeromq-and-multiple-subscribe-filters-in-python">ZeroMQ and multiple subscribe filters in Python</a></p>
  
  <p>It looks simpler to specify ports.</p>
  
  <p>I do not mean to connect to multiple topics. I mean that different parts of application will connect to different ports.</p>
