Main components

• Home Agent (HA)
• Foreign Agent (FA)

Mobile IP – the long term vision (also for mobile networks)

• HA, FA
• IPv6
• real-time requirements?

Mobile-IP developments

• IDMP - intra-domain mobility protocoll
• Hawaii
• Cellular IP, Cellular IPv6 (CIPv6)
• Hierarchical Mobile IPv6 (HMIPv6)
• Fast Mobile IPv6

• Correspondent does not know IP address of "moved" device, thus sends a request to the HA
• HA forwards to the moved device via Foreign Agent (FA)
• Moved device answers directly to the Correspondent

• replace triangular routing, keep address
• route optimisation
• defined for low-speed mobility

Intra-domain mobility

• Host based routing
• Data integrity protection,

Security

• Sender authentication,
• Data integrity protection,
• Replay protection

• combines IP and mobile components
• challenge: credential distribution
