Seminar on Mobile IPv6
[attachment=25556]
Mobile IPv6 is an IETF standard that has added the roaming capabilities of mobile nodes in IPv6 network. RFC 3775 has described this standard in detail. The major benefit of this standard is that the mobile nodes (as IPv6 nodes) change their point-of-attachment to the IPv6 Internet without changing their IP address
This allows mobile devices to move from one network to another and still maintain existing connections. Although Mobile IPv6 is mainly targeted for mobile devices, it is equally applicable for wired environments.
Definitions and IPv6 features that are needed by Mobile IPv6
Several terms and information are necessary to understand Mobile IPv6: A foreign link defines a link that is not the mobile nodes home link. A Care-of address denotes an address that is used by the mobile node while it is attached to a foreign link. Whenever a mobile node moves from the home link to a foreign link, it is always (still) reachable by its home address, regardless of its location in IPv6 network.
Home address signifies that the mobile node is logically connected to the home link. Also, the association of a home address with a care-of address for a mobile node is known as a binding. Home agent is a router (on the home link) that maintains registrations of mobile nodes that are away from home and their current addresses. A Correspondent node is an IPv6 (not necessarily Mobile IPv6 capable) node that communicates with a mobile node.
