title: Netty Server handling multiple clients
body: <p>I want to set up a server that handles a calculation request. This calculation can be split up in x partial calculations so I want to have multiple clients that may register to the server. The server should have a list of these registered clients. </p>
  
  <p>When the server receives a request it splits the calculation in its x parts and afterwards sends each calculation request to the clients and waits for the clients to end its calculation.</p>
  
  <p>Does someone have an idea how to do this with netty or any other technology that may be easier? Netty seemed to be the right solution for me but I don't know how I can register and save the clients in the server and afterwards send the calculation parts to the clients and wait for them.</p>
