VI. Other Notes

Additional notes

RFC 3522 ("The Eifel Detection Algorithm for TCP") has a known IPR disclosure, as explained in Section 4 of RFC 3522.

draft-zimmermann-tcpm-spurious-rxmit-00 apparently specifies an alternative method for spurious retransmission detection that seems related to RFC 3522. The IPR disclosed for RFC 3522 may or may not apply to this I-D.
