Well. On the standards track you're correct (RFC 3390 & 5681). However, RFC 6928 says the initial window can be 10---which is where I assumed the number in the email thread came from---as experimental. You can count me as someone who doesn't think there is much distinction between standards track and experimental in this case except that it makes some people feel better to call it "experimental". I don't have great current numbers, but 10 is in pretty wide use, I believe. So, a limit of 10 segments here seems fine (and from my understanding of what ekr said would be consistent with current DTLS experience). allman --=_MailMate_1EA36721-C480-40A9-943F-81BE82DF71D8_= Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iG8EARECAC8WIQR2wAGDYhexl/6SqCRbKutazjIizgUCYGN7VxEcbWFsbG1hbkBp Y2lyLm9yZwAKCRBbKutazjIizgZFAJkBo0KGw9DMPKfPUruoYnt4YGplcgCfcNs0 WQ21r2/ONFi1sKmtXa4h1iI= =rdcV -----END PGP SIGNATURE----- --=_MailMate_1EA36721-C480-40A9-943F-81BE82DF71D8_=--
