I am already tried with ping pong buffer concept for what reason is .

i have a one UDP receiver i should receive upto 10 gb files but during the sequential

execution it might lose the packet(8K).....one packet is 8K ....for 10gb is missing

250 packets and for 1 gb it missing 50 packets.

so i tried with the ping pong concept and circular buffer i wont work .....any one

Solution 1

1. If you are using UDP then you need to include some extra detail in your datagrams to check for lost packets, and have them resent by the server.
2. What do you mean by "ping pong concept"?
3. It is not urgent to anyone but you.

Solution 2

If you need packet reliability, you shouldn't be using UDP, you should be using TCP. UDP is not meant to have high reliability, if you're going to add your own overhead to make it reliable, you're essentially turning UDP into TCP.

Solution 3

1- use TCP instead of UDP if you can
2- if you can not using TCP so you should implement an acknowledgement and resending system in your packet transfer system.

*- TCP is more reliable and also faster than UDP with acknowledgment
