<p class="MsoNormal">I discovered this recently. It may assist you in your efforts for highly scalable systems:</p>

<p class="MsoNormal"><br>In other words, you’re not limited to 16-bits worth of TCP ports on one server.</p>

<p class="MsoNormal">My guess is they use multiple IP addresses (IPv6?) on a single server, but I’m not sure.</p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Isn't MQTT the protocol of the IoT?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">It needs a broker, doesn't it?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Just being curious.</p>

<p class="MsoNormal">Good morning (and happy new year !),</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If you want to build something multi-users, nowadays I'd recommend MQTT: it's not specific to 3D,</p>
<p class="MsoNormal">so you'd still need to create the application on top of it, but you could reach both applications and webapps</p>
<p class="MsoNormal">with it (it can even run on low-end devices), and it's a proper documented standard.</p>
<p class="MsoNormal">Mosquitto on a small linux server is enough to get started,</p>
<p class="MsoNormal">or you could use something like PubNub to not worry about scaling the backend.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">See you,</p>
