Product Features
Version A.03.01 includes the following new features:
• Authorization, Authentication and Accounting (AAA) - The HP-UX Mobile IPv4
extension to the Diameter protocol allows authorization, authentication, and accounting
of Mobile IP users across multiple realms. The protocol incorporates Registration Request
messages into Mobile IP specific Diameter messages. The AAA process can be triggered in
the Mobile IP registration process.
• Dynamic Home Address Allocation - Mobile Nodes can now register and obtain a
dynamically allocated home address in the absence of a static address using Network
Access Identifier (NAI). The Base Mobile IP protocol allows a Mobile Node to be
configured without a home address. Home addresses for such Mobile Nodes are
dynamically allocated during registration process. Dynamic home address allocation is
supported only if registration is authenticated via AAA.
• Dynamic Home Agent Allocation - Mobile Nodes in a foreign network send a
registration request to the AAA server for Home Agent allocation. Home Agent allocation
is directly linked to the home address of the Mobile Node. This home address may either
be a static home address or a dynamically allocated one. This version supports dynamic
Home Agent allocation in both cases.
• Reverse Tunneling - HP-UX Mobile IPv4 software provides reverse tunneling support
in the mobility agents (HA, FA, and HA/FA). This allows for datagrams sent by a Mobile
Node to be tunneled to its Home Agent from its Care-of Address (Foreign Agent or
Co-located). The Home Agent then decapsulates the tunneled datagram and routes it to
the original destination. This feature is desirable when the Mobile Node visits foreign
networks where the routers require that the source address of datagrams be topologically
correct.
Version A.03.01 also includes the following features:
