Function of layers IEEE802.11 --- We will discuss in TG May 2010 Function of layers IEEE802.11 --- We will discuss in TG Network discovery Authentication Privacy (Key Management/Cryptography) IPv4/IPv6 --- Liaison to IETF IP address assignment/DAD Bind MAC address and IP address (ARP/NDP) (Registration related to Mobile IPv4/v6) Name resolution (DNS query) Applications (HTTP, etc…) Hiroki Nakano, Trans New Technology, Inc.

Example: IP address assignment/DAD May 2010 Example: IP address assignment/DAD DHCP do two round-trip packet exchange. Why? They assume existence of multiple DHCP servers. How many environments with .11 has multiple DHCP servers? For instance, if AP has DHCP relay function…? Router Advertisement (IPv6) Broadcast from router. It’s one-way. It’s easy for .11 to convey them. Need to provide framework to piggyback information for them into our FIA frames Hiroki Nakano, Trans New Technology, Inc.

Example: Bind MAC and IP addresses May 2010 Example: Bind MAC and IP addresses AP can knows both MAC and IP addresses of clients. AP implementation can solve this problem. Need to provide framework to piggyback information for them into our FIA frames Hiroki Nakano, Trans New Technology, Inc.

Conclusion To reduce time to setup network before using users… May 2010 Conclusion To reduce time to setup network before using users… We will discuss in TG to finish .11 matter in single roundtrip packet exchange. FIA can also help upper layers by providing framework to piggyback some data for upper layers. Hiroki Nakano, Trans New Technology, Inc.
