The one major problem TCP currently has is the assumption that packet loss is always caused by congestion, which is a simplification that proves most damaging over radio links.
There are smaller problems (but still worth fixing), like TLS over TCP doing a few more round trips more than necessary. QUIC tackles this in particular.
- fulafel 13y agoHow would you change TCP to improve its behaviour here? Current radio link layers (3g, wifi) are designed to play nicely with TCP. Their below-IP layers do their own retransmissions to make up for radio link issues. They have to take into account radio channel congestion - it doesn't help if everyone on the channel just starts shouting louder and repeating themselves.
