User Datagram Protocol

A transport layer communication protocol, UDP is a very common protocol for voice and video traffic.

• The User Datagram Protocol, or UDP, is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups.

• It speeds up communications by not formally establishing a connection before data is transferred.

• This allows data to be transferred very quickly, but it can also cause packets to become lost in transit — and create opportunities for exploitation in the form of DDoS attacks.

  • UDP is connection-less but at the same level as TCP

  • “connection-less” means “send it, see what happens”. For example, sending a letter via snail mail.
