suppose i am listening to the radio on the internet...(using udp)

1 packet is sent from the radio server to my machine.Does this mean that for 10 minutes=1packet??

or does this mean for 10 minutes=i can have 10 packets?

and packet 5 might be lost, it will skip packet 5 and send packet 6...meaning i will not be able to listen to that small part in packet 5 but will receive the data after packet 5.

please clarify this to me...
thanks beforehand.

While packet size can vary it is maxed out at 65,507 bytes per packet. So it would take quite a number of packets to stream ten minutes of music. How many would depend on the actual size of the music file being streamed.

UDP is a not error correcting protocol or order dependent protocol. It also uses the packets in the order recieved at the target computer even if the packets are out of order. Because of the real time usage of video/audio it would not be possible for a corrupted/dropped packet to be resent so it would just go to the next one recieved. So yes if in the middle of a streaming music track packet five is lost then it plays the next one recieved.
Get your facts first, then you can distort them as you please.
