Title : The NewReno Modification to TCP's Fast Recovery Algorithm
Author(s) : T. Henderson, et al.
Filename : draft-ietf-tcpm-rfc3782-bis-00.txt
Pages : 22

RFC 5681 [RFC5681] documents the following four intertwined TCP
congestion control algorithms: Slow Start, Congestion Avoidance, Fast
Retransmit, and Fast Recovery. RFC 5681 explicitly allows
certain modifications of these algorithms, including modifications
that use the TCP Selective Acknowledgement (SACK) option [RFC2883],
and modifications that respond to "partial acknowledgments" (ACKs
which cover new data, but not all the data outstanding when loss was
detected) in the absence of SACK. This document describes a specific
algorithm for responding to partial acknowledgments, referred to as
NewReno. This response to partial acknowledgments was first proposed
by Janey Hoe in [Hoe95].
The purpose of this revision from [RFC3782] is to make errata changes
and to adopt a proposal from Yoshifumi Nishida to slightly increase
the minimum window size after Fast Recovery from one to two segments,
to improve performance when the receiver uses delayed acknowledgments.
