  1. Parallel processing for upper layer Date: 2010-08-25 Authors: Hiroki Nakano, Trans New Technology, Inc.

  2. Various approaches Orange parts must be developed by FIA in future.

  3. Plan A AP AS DHCP/Default Gateway STA Association Request with: AS Selector Request for IP address AP uses DHCP to obtain IP address. EAPOL-Start DHCP Discovery Parallel Processing for EAP and IP DHCP Offer EAP-GPSK Association Response with: IP address and other configurations MAC address of Default Gateway DHCP Request DHCP ACK EAPOL-Success EAPOL-Key ARP Request to Default Gateway ARP Reply from Default Gateway AP waits for finishing both processes for EAP and IP.

  4. Dirty-but-fast deployment of Plan A STA Inside STA EAPOL-Start AP AS DHCP/Default Gateway Existing L3 New .11 driver Parallel Processing for EAP and IP EAP-GPSK Basically, Plan A requires STA to support new L3 configuration protocol. EAPOL-Success EAPOL-Key New .11 driver emulates DHCP server for existing IP layer trying to get IP address. DHCP Procedure

  5. Plan B AP AS DHCP/Default Gateway STA Association Request with: AS Selector DHCP Discovery Piggyback EAPOL-Start DHCP Discovery Parallel Processing for EAP and IP DHCP Offer EAP-GPSK Any packet can be used to transfer DHCP packets Piggyback Association Response with: DHCP ACK Gratuitous ARP for Default Gateway Piggyback DHCP Request EAPOL-Success DHCP ACK EAPOL-Key ARP Request to Default Gateway ARP Reply from Default Gateway Piggyback AP waits for finishing both processes for EAP and IP.

  6. Differences between Plan A and B
