I am trying to send a series of bitmaps via a UDP Multicast socket using Dgram. I have read that this is limited in byte size and therefor am having issues.
My question is:
do i have to break the bitmap into smaller fragments to send?
or
is there a better way?
Does anyone have an idea of how VLC and the like do it?
I really want to know if i'm heading in the right direction or should change direction.
Relying on IP Fragmentation will not be good. Say one fragment is dropped by the network, then the sender will have to send the whole bitmap again. With a good reliable UDP protocol the sender machine should be able to automatically send only any dropped packets.
There seem to be a few libraries which support reliable UDP see e.g. http://stackoverflow.com/questions/107668/what-do-you-use-when-you-need-reliable-udp and http://stackoverflow.com/questions/31572/broadcast-like-udp-with-the-reliability-of-tcphttp://www.alanjmcf.me.uk/ Please follow-up in the newsgroup. If I help, mark the question answered
