What’s Included in HP-UX Mobile IPv6 A.01.00
The following sections describe the functionality, features, and content of HP-UX Mobile IPv6
A.01.00.
Functionality
HP-UX Mobile IPv6 includes a Kernel-resident STREAMS module, mip6mod, that processes
and generates IPv6 Mobility Headers, and utilizes the HP-UX IPv6 Router Advertisement
Daemon—also delivered in TOUR 2.0—to provide the following server functionality:
• Home Agent support
• Correspondent Node support
NOTE The same server can be both a Home Agent and a Correspondent Node.
Home Agent Support
Home Agents are nodes or routers that provide mobility services to Mobile Nodes from their
home network. During Mobile IPv6 basic operation, a Mobile Node gets a temporary Care-of
Address identifying its current location after it travels to a foreign network. The Home Agent
intercepts data packets sent to the Mobile Node’s Home Address and transparently routes
them to the Mobile Node’s current Care-of Address on the foreign network.
Corespondent Node Support
Correspondent Nodes are any IPv6 node communicating or corresponding with a Mobile
Node, for example Web servers providing location-sensitive resources to Mobile Nodes. In
most cases, the Mobile Node and Correspondent Node communicate using Route
Optimization. Mobile IPv6 basic operation is only used in the initial communication, when the
Correspondent Node does not have information about the Mobile Node’s Care-of Address, and
in cases where the Correspondent Node does not support Mobile IPv6 Route Optimization.
NOTE Correspondent Nodes do not use or require the HP-UX IPv6 Router
Advertisement Daemon.
