Right, if a packet gets delayed by 400ms, that's not going to break TCP, but you might as well consider it dropped for a real-time call.

- fulafel 7y agoIf it's frequent (3-20pct), it's going to break your web browsing experience on TCP too because it had to be retransmitted. The original eventually appearing 400ms later doesn't make a difference.
- cma 7y agoMain threshold is if it is beyond RTT or not. But if it is 20pct frequent, there's 4% that are held up and then have their retransmission held up too. Back to voice, many voice codecs will do forward error correction, but if jitter affects multiple packets in the sequence similarly instead of being independent that might not be enough.
