<h3>The UDP Transport</h3>

<p>The UDP transport allows clients to connect to a remote ActiveMQ broker using raw UDP</p>

<p>Note that by default UDP is not reliable; datagrams can be lost so you should add a reliability layer to ensure the JMS contract can be implemented on a non-reliable transport.</p>

<h4>Configuration Syntax</h4>

<p><strong>udp://hostname:port?transportOptions</strong></p>
