Glossary

see Mobility binding.

The message to the Mobile Node, in response to it’s Binding Update, acknowledging the Mobile Node’s Binding Update and indicating whether it was accepted or rejected. The Binding Acknowledgement also includes a fixed lifetime for the registration.

A cache of bindings for other IPv6 nodes that each IPv6 node maintains.

Used to authorize the Binding Update and Binding Acknowledgement messages. The Return Routability procedure provides a method to create a binding management key.

The message that supplies a new binding to an entity that needs to know the new Care-of Address for a Mobile Node. The binding update contains the Mobile Node's home address, new Care-of Address, and a new registration lifetime.

An IP address which identifies the Mobile Node's current point of attachment to the Internet, when the Mobile Node is not attached to the home network.

Part of the Return Routability procedure, a response to the Care-of Test Init message sent directly to the Mobile Node from the Correspondent Node and containing Binding Management Key (Kbm) material.

Part of the Return Routability procedure, a message sent directly to the Correspondent Node from the Mobile Node to initialize the Care-of Test.

A peer with which a Mobile Node is communicating. A Correspondent Node may be either mobile or stationary.

The process of incorporating an original IP packet (less any preceding fields such as a MAC header) inside another IP packet, making the fields within the original IP header temporarily lose their effect.

The network to which the Mobile Node is attached when it is not attached to its home network. The Mobile Node's Care-of Address is local to the foreign network and is reachable from the rest of the Internet.

A single, fixed IPv6 address a IPv6 Mobile Node can use for extended periods of time, regardless of its current attachment point. The Mobile Node’s home address is a unicast routable (global) address, with the network prefix of the Mobile Node’s home network.

A router node on a Mobile Node's home network that captures packets addressed to the Mobile Node’s home address forwards the packets to the Mobile Node’s Care-of Address.

The network associated with the Mobile Node's home address. IP routing mechanisms will deliver data-packets destined to a Mobile Node's Home Address to the Mobile Node's Home Network.

Part of the Return Routability procedure, a response to the Home Test Init message sent to the Mobile Node—through its Home Agent— from the Correspondent Node and containing Binding Management Key (Kbm) material.

Part of the Return Routability procedure, a message sent to the Correspondent Node from the Mobile Node—and through the its Home Agent—to initialize the Home Test.

Internet Engineering Task Force.

IP Security Protocol that provides encryption and authentication services for IP packets.

Command line administrative tool for HP-UX Mobile IPv6 that reports various information on the Mobile IPv6 kernel module and router advertisement daemon.

Command line configuration tool for Mobile IPv6 that edits Mobile IPv6 configuration files.

A host that may change its network attachment point from one network or subnetwork to another. A Mobile Node is assigned a fixed home address on a home network, which Correspondent Nodes may use to address packets to the Mobile Node, regardless of the Mobile Node’s current network attachment point.

The triplet of numbers that associates a Mobile Node's home address with its Care-of Address and registration lifetime.

An IPv6 extension header used in Mobile IPv6 to create and manage mobile node bindings.

The process by which a Mobile Node determines it has moved away from its home network.

A set of IPv6 protocol features that describe how nodes discover and interact with neighboring nodes on their current link.

The process by which the Mobile Node informs the Home Agent of its current Care-of Address.

How long the mobility agents may use a mobility binding.

A procedure between the Mobile Node and Correspondent Node to authorize binding procedures by the use of cryptographic token exchange.

The Correspondent Node forms a tunnel with the Mobile Node’s Care-of Address so that packets from the Correspondent Node to the Mobile Node bypass the Home Agent.

Daemon for IPv6 that sends router advertisements and listens for router solicititations. The router advertisement daemon allows hosts to automatically configure their addresses without manual intervention.

A Neighbor Discovery function in IPv6 that mobile nodes use locate routers on their current link.

An association between two nodes that specifies security parameters, including cryptography algorithm, cryptography key and expiration time.

An index identifying a security association between two nodes.

The path followed by an IP packet when it is encapsulated in a second IP packet with an alternate IP destination addresses. While it is encapsulated, the internal datagram is protected from normal Internet routing. The decapsulating agent decapsulates the original datagram and so it can be delivered to the original destination address.

The act of bypassing the normal internet routing for a packet by encapsulating the packet within a new IP header containing an alternate destination IP address.
