TCP and UDP over IPv6 Jumbograms
RFC 2147, “TCP and UDP over IPv6 Jumbograms”, is a Proposed Standard document published in May 1997 by D. Borman. It has been obsoleted by RFC 2675 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
IPv6 supports datagrams larger than 65535 bytes long, often referred to as jumbograms, through use of the Jumbo Payload hop-by-hop option. The UDP protocol has a 16-bit length field that keeps it from being able to make use of jumbograms, and though TCP does not have a length field, both the MSS option and the Urgent field are constrained by 16-bits. This document describes some simple changes that can be made to allow TCP and UDP to make use of IPv6 jumbograms. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
