<hr><a name="_details"></a><h2>Detailed Description</h2>
UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts. Unreliable Datagram Peer Associations.
<p>
Two UDP sockets are typically used on alternating port addresses to assure that sender and receiver data does not collide or echo back. A UDP Duplex is commonly used for full duplex real-time streaming of UDP data between hosts.
