  2. Access Router Prefix Management in IEEE802.16 networks • Point-to-Point Link mode is recommended for IEEE802.16 networks. • Different MN has different prefixes • Prefixes should be allocated when MN attaches to AR; Prefixes should be released when MN detaches AR • AR can offload most of prefix management to a Diameter server Diameter Server AR MN1 MN2 … … MNn

  3. Local Mobility Anchor Prefix Management in Proxy MIPv6 • PMIPv6 supports only point-to-point access link types . • Using PBU and PBA messages MAG receives prefix from LMA • Diameter protocol can be used for LMA to get prefixes from an external Diameter server LMA Diameter Server MAG MN1 MN2 … … MNn

  4. Home Agent Prefix Management in NEMO • draft-ietf-nemo-prefix-delegation-02 is used for prefix delegation between HA and MR • Diameter protocol can be used for HA to get prefixes from an external Diameter server HA Diameter Server MR MN1 MN2 … … MNn

  5. Diameter-PD vs DHCP-PD • Both solutions are complementary with each other. • Operators can choose a solution based on deployment environment. • Prefix delegation is a natural extension to IP address management. Diameter and DHCP are harmonic in address management. So they should be harmonic in prefix delegation.
