    // millis and time in nanos.

    // other end since they may take different routes to get there.
    // Behind NAT, many game clients may be coming over the same
    // IP address from the server's perspective and they may have
    // their UDP ports mapped all over the place.
    //
    // Since currentTimeMillis() is absolute time and nano time
    // is roughtly related to system start time, adding these two
    // together should be plenty unique for our purposes.  It wouldn't
    // hurt to reconcile with IP on the server side, though.

Example 5 with ClientRegistrationMessage

use of com.jme3.network.message.ClientRegistrationMessage in project jmonkeyengine by jMonkeyEngine.

the class KernelAdapter method dispatch.

/**
     *  Note on threading for those writing their own server 
     *  or adapter implementations.  The rule that a single connection be 
     *  processed by only one thread at a time is more about ensuring that
     *  the messages are delivered in the order that they are received
     *  than for any user-code safety.  99% of the time the user code should
     *  be writing for multithreaded access anyway.
     *
     *  <p>The issue with the messages is that if a an implementation is
     *  using a general thread pool then it would be possible for a 
     *  naive implementation to have one thread grab an Envelope from
     *  connection 1's and another grab the next Envelope.  Since an Envelope
     *  may contain several messages, delivering the second thread's messages
     *  before or during the first's would be really confusing and hard
     *  to code for in user code.</p>
     *
     *  <p>And that's why this note is here.  DefaultServer does a rudimentary
     *  per-connection locking but it couldn't possibly guard against
     *  out of order Envelope processing.</p>
