UDP with parity checks don't give you shit - in fact, parity check on top of UDP gives you absolutely nothing since UDP already has a checksum. You need to also do sequence numbering because your packets will come out of order and get dropped. You need to do retransmission request and maintain a reordering buffer. You need to somehow do congestion control. In other words, you need to re-implement TCP, except you don't know shit about transport protocols so your implementation will be complete garbage.

That doesn't even make any sense. Also, SSL/TLS says "Hi!"
