Summary of Proposal Hard coding or DHCP to discover Mobility Manager (MM) Mobile Node (MN) discovers MM at initialization Depends on number of MMs DHCP as per draft-daniel-dhc-mihis-opt-02.txt (Park, et al.) UDP as MIH transport mechanism between MM and MN Easy to implement, simple & fast, used by many other control protocols e.g. SIP IPSec for security mechanism Existing MIH functionalities in order to Setup and keep track of MIH node identifiers, session and transaction identifiers Discover capabilities of MIH peers Provide reliability with optional ACK bit fields Retransmission timers at MIH application layer to complement UDP for reliability And associated congestion control mechanism |
