UDP doesn't suck! It's the BEST L4 protocol for THESE types of applications...

UDP is often defined by comparing it to TCP. Which leaves UDP with definitions like "no flow control" and "no reliability". These types of comparison tend to give UDP a bad reputation. UDP in fact is much cooler than people realize, and in this video we're going to illustrate the three types of applications that are better suited for UDP than they are for TCP.
