IETF RFC 6298
Computing TCP’s Retransmission Timer
|Publication Date:||1 June 2011|
This document defines the standard algorithm that Transmission Control Protocol (TCP) senders are required to use to compute and manage their retransmission timer. It expands on the discussion in Section 184.108.40.206 of RFC 1122 and upgrades the requirement of supporting the algorithm from a SHOULD to a MUST. This document obsoletes RFC 2988.
