A set of addresses designated by the home network administrator for use by mobile nodes that need a home address.
A message periodically broadcasted by home agents and foreign agents to advertise their presence on any attached link.
The process by which a mobile node determines if it has moved, its current location, and its care-of address on a foreign network.
A tunnel that can transmit datagrams in both directions.
A home agent table that associates a home address with a care-of address, including remaining lifetime and time granted.
A mobile node's temporary address used as a tunnel exit point when the mobile node is connected to a foreign network.
Any network other than the mobile node's Home Network.
An optional form of tunneling that can be supported by home agents, foreign agents, and mobile nodes. GRE enables a packet of any network-layer protocol to be encapsulated within a delivery packet of any other (or same) network-layer protocol.
An IP address assigned for an extended period to a mobile node. The address remains unchanged when the node is attached elsewhere on the Internet or an organization's network.
A network having a network prefix matching that of a mobile node's home address.
The Internet-standard protocol for tunneling IPv4 packets within IPv4 packets.
An iterative cryptographic hash function used for message authentication.
An optional form of IPv4 in IPv4 tunneling that can be supported by home agents, foreign agents, and mobile nodes. Minimal Encapsulation has 8 or 12 less bytes of overhead than does IP in IP Encapsulation.
A host or router that can change its point of attachment from one network to another while maintaining all existing communications, using its IP home address.
Either a home agent or a foreign agent.
The association of a home address with a care-of address, along with the remaining lifetime of that association.
A collection of security measures, such as an authentication algorithm, between a pair of nodes, which are applied to Mobile IP protocol messages exchanged between the two nodes.
A host or a router.
Used to uniquely identify the mobile node in the format of user@domain.
The process by which a mobile node registers its care-of address with its home agent when it is away from home.
An integer that specifies the row in the SADB (security associations database) that a receiver should use to decrypt a received packet.
The path followed by a datagram while it is encapsulated.
A single, secure, logical network that uses tunnels across a public network such as the Internet.
A network other than a mobile node's home network, to which the mobile node is currently connected.
The list of mobile nodes visiting a foreign agent.
