Mobile IPv6 Fast Handovers
RFC 5568, “Mobile IPv6 Fast Handovers”, is a Proposed Standard document published in July 2009 by R. Koodli. It obsoletes RFC 5268. It has since been updated by RFC 7411. The canonical text is published by the RFC Editor.
Abstract
Mobile IPv6 enables a mobile node (MN) to maintain its connectivity to the Internet when moving from one Access Router to another, a process referred to as handover. During handover, there is a period during which the mobile node is unable to send or receive packets because of link-switching delay and IP protocol operations. This "handover latency" resulting from standard Mobile IPv6 procedures (namely, movement detection, new Care-of Address configuration, and Binding Update) is often unacceptable to real-time traffic such as Voice over IP (VoIP). Reducing the handover latency could be beneficial to non-real-time, throughput-sensitive applications as well. This document specifies a protocol to improve handover latency due to Mobile IPv6 procedures. This document does not address improving the link-switching latency.
This document updates the packet formats for the Handover Initiate (HI) and Handover Acknowledge (HAck) messages to the Mobility Header Type. [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.
