A live videо cоnferencing аpplicаtiоn sends 12 numbered video frаmes from Host A to Host B: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. Host B receives the frames in this order: 1, 2, 3, 6, 5, 7, 10, 12, 11. Frames 4, 8, and 9 do not arrive. The transport service used by the application does not automatically guarantee ordering, acknowledgments, or retransmission. a) In what order are the received frames delivered to the application? b) Does the transport service automatically reorder or retransmit the missing frames? c) If the video application needs better reliability, what could it add at the application level? d) Does UDP have built-in congestion control? If No, why can this be a problem?
