  1. Requirements for Ad Hoc IP Address Autoconfiguration draft-jeong-manet-addr-autoconf-reqts-02.txt Jungsoo Park & Jaehoon Paul Jeong ETRI {pjs, paul}@etri.re.kr http://www.adhoc.6ants.net 2nd August 2004 IETF-60 MANET WG

  2. Why is MANET Address Autoconf necessary? • Four basic MANET unicast routing protocols have been experimental RFCs. • AODV, DSR, OLSR and TBRPF • Next Step of MANET WG? • Addressing is one of the most essential requirements in IP networking. • Automatic IP address configuration is necessary in MANET experiencing dynamic topology changes. • Various approaches have been suggested in the research domain • Stateless vs. Stateful approaches • Strong DAD vs. Weak DAD • MANET WG has already included MANET Address Autoconf in its Charter. • Therefore, it is time to develop MANET IP Address Auto-configuration from Engineering Philosophy. • First of all, MANET WG should define the requirements for MANET Address Autoconf. IETF-60 MANET WG

  3. Requirements for MANET Address Autoconf(draft-jeong-manet-addr-autoconf-reqts-01.txt) - 1/3 • Join and Departure of Mobile Nodes [R1] Address autoconf protocol MUST support timely autoconfiguration of IP address for a mobile node. [R2] Address autoconf protocol MAY support mechanisms to probe whether a mobile node moves into another MANET. [R3] Mobile nodes using address autoconf protocol MUST validate allocated IP addresses when powering up or rebooting. [R4] Mobile nodes using address autoconf protocol MAY validate allocated IP addresses when moving into a new network. IETF-60 MANET WG

  4. Requirements for MANET Address Autoconf (draft-jeong-manet-addr-autoconf-reqts-01.txt) - 2/3 • Network Partitioning and Merging [R5] Ad hoc address autoconf protocol MUST detect and resolve address conflicts in a timely manner and on an ongoing basis. [R6] Ad hoc address autoconf protocol MUST allow conflicted address replaced with another. [R7] Ad hoc address autoconf protocol SHOULD minimize the damage, such as loss of delivered packets, due to address replacement. [R8] Addresses SHOULD be allocated or autoconfigured in a way that minimizes the probability that two or more nodes will have the same address. [R9] In order to detect duplicate addresses, ad hoc address autoconf protocol MAY get the aid of ad hoc routing protocol. IETF-60 MANET WG

  5. Requirements for MANET Address Autoconf (draft-jeong-manet-addr-autoconf-reqts-01.txt) - 3/3 • Internet Connectivity [R10] MANET SHOULD allow configuration of zero or more gateways for the global connectivity to the Internet. [R11] Mobile Node that desires Internet connectivity MAY have a globally routable IP address. • Other Scenarios? • IPv6 Considerations • We need your feedback and suggestion. IETF-60 MANET WG

  6. Procedure of MANET Address Autoconf(draft-jeong-adhoc-ip-addr-autoconf-03.txt), discussed at IETF-57 • Step 1: Address Selection • How to select one of IP addresses in the address space. • Step 2: Duplicate Address Detection • How to detect a duplicate address • Step 3: Address Change Negotiation • Which node should perform a reallocation procedure • Step 4: Maintenance of Upper-layer Sessions • How to let an upper-layer session avoid a connection breakage IETF-60 MANET WG

  7. Discussion • Will MANET WG accept MANET Address Autoconf Requirements as a new WG item? • draft-jeong-manet-addr-autoconf-reqts-02.txt • This work will make MANET WG’s new objective more concrete. • Suggestion and Question? IETF-60 MANET WG
