A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : IPv6 Path MTU Updates Author(s) : Fred L. Templin Filename : draft-generic-6man-tunfrag-03.txt Pages : 6 Date : 2012-07-10 Abstract: IPv6 intentionally deprecates fragmentation by routers in the network. Instead, links with restricting MTUs must either drop each too-large packet and return an ICMP Packet Too Big message or perform link-specific fragmentation (also known as "link adaptation") at a layer below IPv6. This latter category of links is often performance-challenged to accommodate steady-state link-specific fragmentation and reassembly to the point that it would be highly desirable to push the workload back to the IPv6 communication endpoints. A common case that exhibits these link characteristics is seen for IPv6-within-IP tunnels. Additionally, IPv6 nodes could better adapt to path MTUs of various sizes by using either a small amount of host-based fragmentation and/or path probing as necessary.This document therefore proposes an update to the base IPv6 specification to better accommodate path MTU issues.
