HIP Mobile Router

• HIP Mobile Router (MR)
• Supports mobile HIP hosts
• MR hides the network mobility from MRs clients
• Private address space
• Heterogeneous networks
• e.g. LAN, WLAN, 3G
• IPv4, IPv6
• MR can connect IPv4 networks to IPv6 networks

HIP Mobile Router

• Service discovery
• I1 and UPD SEQ trigger registration exchange
• On-path discovery passive mode
• Signaling delegation
• Delegation between HITs
• MNs register at MR, delegate signaling rights
• MR sends location updates on behalf of MNs
• Certificate-based authorization authentication
• MR SIMA based on HITs
• Not possible to base on protocol/port, only ESP
  packets
• E.g. HIT ltAgt prefers to use 3G access

HIP MR

• Signaling delegation to minimize signaling
• MN delegates to MR
• MR can further delegate signaling to a signaling
  proxy
• Only one location update from MR

Delegation Register all known HITs
