The IESG has approved the following document: - 'The NewReno Modification to TCP's Fast Recovery Algorithm ' <draft-ietf-tsvwg-newreno-02.txt> as a Proposed Standard This document is the product of the Transport Area Working Group Working Group. The IESG contact persons are Jon Peterson and Allison Mankin. Technical Summary This document advances the Experimental NewReno specification defined in RFC2582 to Proposed Standard. The main change in this document relative to RFC 2582 is to specify the Careful variant of NewReno's Fast Retransmit and Fast Recovery algorithms. The base algorithm described in RFC 2582 did not attempt to avoid unnecessar multiple Fast Retransmits that can occur after a timeout (described in more detail in the section above). However, RFC 2582 defined "Careful" and "Less Careful" variants that avoid these unnecessary Fast Retransmits, and recommended the Careful variant - this specification only defines the "Careful" variant. This document also specifies two heuristics that the TCP sender MAY use to decide to invoke Fast Retransmit even when the three duplicate acknowledgements do not cover more than "recover". Working Group Summary The TSVWG strongly supported the advancement of this document. Protocol Quality This document was reviewed for the IESG by Jon Peterson.
