Abstract
RFC 5681 documents the following four intertwined TCPcongestion control algorithms: slow start, congestion avoidance, fastretransmit, and fast recovery. RFC 5681 explicitly allowscertain modifications of these algorithms, including modificationsthat use the TCP Selective Acknowledgment (SACK) option (RFC 2883),and modifications that respond to "partial acknowledgments" (ACKsthat cover new data, but not all the data outstanding when loss wasdetected) in the absence of SACK. This document describes a specificalgorithm for responding to partial acknowledgments, referred to as"NewReno". This response to partial acknowledgments was first proposedby Janey Hoe. This document obsoletes RFC 3782. [STANDARDS-TRACK]
