Introducing HP-UX Mobile IPv6

2
Document Information
This White Paper from the Hewlett-Packard Company introduces the HP-UX Mobile IPv6 product and
describes the numerous benefits the server software offers as it provides mobility support in IPv6
networks.
Intended Audience
This White Paper is intended for IT professionals—specifically, network officers, architects, and
administrators. However, the tone, scope, and depth of the document are also suitable for readers with
limited IP training and a casual curiosity about HP-UX Mobile IPv6. Use the documents listed in the
Additional Information section to get detailed information about HP-UX Mobile IPv6.
Terms and Definitions
Every technical field has a unique and specific vocabulary. The following table lists and briefly defines
some the fundamental terminology related to HP-UX Mobile IPv6 and this document. The terminology
not listed in the table below is defined in the body of this document.
Term Definition
Care-of address The temporary IP address of a Mobile Node attached to a Foreign
Network. The Care-of Address has the same network prefix as the Foreign
Network. The Mobile Node can acquire a Care-of Address using IPv6
stateless auto-configuration, or by using a stateful configuration method
such as DHCP.
Connectathon Multi-vendor software and hardware event for interoperability testing.
Data packet IP message header plus payload
Foreign
Network
Any network link whose network prefix is not the same as the network
prefix of the Mobile Node’s home address (any network other than the
Home Network).
Home address A single, fixed IPv6 address each Mobile Node uses to send and receive
IP data packets, regardless of its current location and for extended
periods. The Mobile Node’s Home Address is an IPv6 unicast routable
(global) address with a network prefix on the Mobile Node’s Home
Network.
Home Network The network link whose network-prefix is the same as the network-prefix of
the Mobile Node’s Home Address, and the network to which the Mobile
Node is normally attached.
IETF Internet Engineering Task Force
Ingress filtering The process by which routers drop IP data-packets that appear to be
arriving from a location inconsistent with the source address of the data
packet.
IPSec Internet Protocol Security is a suite of protocols for securing data-packets
at the IP layer.
IPv6 Internet Protocol version 6 (the successor to IPv4)
Mobile IPv6 Mobility Protocol for IPv6
Mobile Node A node capable of moving and changing network attachment points, such
as a laptop, PDA, or cell phone.
Network prefix A bit string consisting of some number of initial bits of an IP address. All
nodes on the same network link share the same network prefix.
Node Any computing device that is attached to an IPv6 network and capable of
transmitting IP data-packets, as the start-, redistribution-, or end-point.
