An application program that uses UDP assumes full responsibility for all issues of reliability, including data loss, data integrity, packet latency, data sequencing, and loss of connectivity.

UDP is used extensively in voice over Internet Protocol VoIP and stream-oriented multimedia applications, where compression techniques are designed to mitigate such issues over a highly shared packet network. Similarly, with online gaming, experiencing less-than-ideal video or sound for a few moments is preferable to waiting for a clear transmission and risking losing the game in the interim.

TCP ensures that the data is sent in order, received, and that nothing is lost along the way. This takes more time but results in more consistent transmissions. UDP does not require any of this. It sends the data without any communication between the sender and the receiver. Because UDP is so susceptible to a DDoS attack, you need a solution like FortiDDoS to differentiate between healthy traffic and traffic being thrown at your server just to overwhelm it.
