title: Is UDP Considered to be a "Best-Effort" Service?
body: <p>I would like to know if UDP is considered to be a "best-effort" service?</p>
  
  <p>The reason I ask is because there are no guarantees that any of the packets will reach their destination/s at all.  Therefore, could UDP be classed as "best-effort" or is there another term which is deemed the "correct" way of describing this?</p>
  
  <p>Thanks.</p>
