The TCP Large Windows Working Group is chartered to produce a specification for the use of TCP on high-delay, high-bandwidth paths. To this end, this working group recommended ``TCP extensions for long-delay paths'' (RFC 1072), and ``TCP Extension for High-Speed Paths'' (RFC 1185) be published jointly as a Proposed Standard. Deficiencies in the technical details of the documents were identified by the End-to-End Research Group of the IRTF. Rather than progress the standard with known deficiencies, the IESG tasked the End-to-End Research Group to fix and merge these two documents into a single protocol specification document. This review was done on the e2e-interest@isi.edu mailing list. The TCP Large Windows Working Group is being resurrected for a one time meeting, to review and if appropriate, approve this new document.
