FEC is usually used in addition to resending.
- jessriedel 9y agoThanks! If FED is standard for deep space and Musk know this (both reasonable), do you have any idea what he might have meant by "then do a batch resend of the CRC-failed packets"? Is it just that guaranteeing zero packet losses has a large overhead (surprising to me), so that the optimal FED protocol in deep space does in fact include a bit of resending?
