Network Working Group H. Soliman Request for Comments: 5380 Elevate Technologies Obsoletes: 4140 C. Castelluccia Category: Standards Track INRIA K. ElMalki Athonet L. Bellier INRIA October 2008 Hierarchical Mobile IPv6 (HMIPv6) Mobility Management Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document introduces extensions to Mobile IPv6 and IPv6 Neighbour Discovery to allow for local mobility handling. Hierarchical mobility management for Mobile IPv6 is designed to reduce the amount of signalling between the mobile node, its correspondent nodes, and its home agent. The Mobility Anchor Point (MAP) described in this document can also be used to improve the performance of Mobile IPv6 in terms of handover speed. Soliman, et al.

Standards Track [Page 2] RFC 5380 HMIPv6 October 2008 1. Introduction This specification introduces the concept of a hierarchical Mobile IPv6 network, utilising a new node called the Mobility Anchor Point (MAP). Mobile IPv6 [RFC3775] allows nodes to move within the Internet topology while maintaining reachability and ongoing connections between mobile and correspondent nodes. To do this, a mobile node sends binding updates (BUs) to its home agent (HA) every time it moves. The mobile node may send data packets via its home agent immediately after sending the binding update, but the home agent will not be able to route traffic back to the mobile node before it receives the binding update. This incurs at least half a round-trip delay beforeShow full document text
