Re: [quicwg/base-drafts] Improve ACK_ECN frame encoding (e.g., use bit-vector) (#1439)

[MikkelFJ <[e-mail]>]

@larseggert this is where your bloom filter comes in handy: just define epochs for the filters lifetime and check duplicates against the two most recent bloom filter epochs and let idempentency deal with false positives. Any encrypted bits could be used directly to index a bloom filter. For example if you have width 256 bits, you can choose the first four encrypted bytes to index a bit in the bloom filter (do some math to get the probabilities right). Eventually the filter gets too densely populated and a new epoch is needed.
