java - Protocol for downloading file -

i looking protocol non-blocking(does not wait missing packets) udp tracks missing packets can download missing packets later/in parallel. main objective increment download speed avoiding waiting time packets , still getting finish file. kindly if there out there can help increment download speed name it. thanks.

short answer: don't. udp not have equivalent tcp's sequence number / acknowledgement number mechanism allow track packets , observe packet loss.

if higher-level protocol that's running on top of udp (rtp, tftp, etc.) has sort of identification number or sequence number or block number unique per packet , changes in predictable way, display number in custom column , manually missing numbers, there no way in udp protocol identify missing packets.
