MN See Mobile Node.
Movement Detection The process by which a
Mobile Node determines it has moved away from its
home network.
Mobile Node 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.
mip6admin Command line administrative tool for
HP-UX Mobile IPv6 that reports various information
on the Mobile IPv6 kernel module and router
advertisement daemon.
mip6config Command line configuration tool for
Mobile IPv6 that edits Mobile IPv6 configuration
files.
Mobility Binding The triplet of numbers that
associates a Mobile Node's home address with its
Care-of Address and registration lifetime.
Mobility Header An IPv6 extension header used in
Mobile IPv6 to create and manage mobile node
bindings.
Neighbor Discovery A set of IPv6 protocol
features that describe how nodes discover and
interact with neighboring nodes on their current
link.
Registration The process by which the Mobile
Node informs the Home Agent of its current Care-of
Address.
Registration Lifetime How long the mobility
agents may use a mobility binding.
Return Routability A procedure between the
Mobile Node and Correspondent Node to authorize
binding procedures by the use of cryptographic token
exchange.
Route Optimization 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.
Router Advertisement Daemon 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.
Router Discovery A Neighbor Discovery function
in IPv6 that mobile nodes use locate routers on their
current link.
rtradvd See Router Advertisement Daemon.
Security Association An association between two
nodes that specifies security parameters, including
cryptography algorithm, cryptography key and
expiration time.
Security Parameters Index An index identifying
a security association between two nodes.
SPI See Security Parameters Index.
Tunnel 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.
Tunneling 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.
