    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 ICMPv6 Packet Too Big (PTB) message or perform link-specific fragmentation and reassembly (also known as "link adaptation") at a layer below IPv6. This latter category of links is often performance-challenged to accommodate steady-state link adaptation. A common case that exhibits these link characteristics is seen for IPv6-within-IP tunnels. Additionally, IPv6 nodes can avoid path MTU discovery issues even when no link adaptation is necessary by performing a small amount of fragmentation and/or by probing the path as necessary. This document therefore proposes an update to the base IPv6 specification to better accommodate path MTU issues.},
