   1. 
      TGai Upper Layer Setup Proposal by Hitoshi Morioka (ROOT) 11-11/0977r2
      
      1. 
         DNS query is not required. (Gabor)
         
      2. 
         Our proposal doesn’t violate layer manner. (Ping)
         
      3. 
         Sorry, I misunderstood and will correct. (Hitoshi)
         
   2. 
      Upper Layer Data IE by Hiroki Nakano (Trans New Technology) 11-11/1167r0
      
      1. 
         How AP to recognize which upper layer packet to carry with Assoc. Resp? (Hitoshi)
         
      2. 
         It’s by operator’s configuration. (Hiroki)
         
      3. 
         Is deep inspection required? (Hitoshi)
         
      4. 
         It’s allowed. (Hiroki)
         
      5. 
         Without deep inspection and knowledge about upper layer protocol in AP, it’s basically same as function specific IE. (Hitoshi)
         
      6. 
         Without deep inspection, there are security issues. AP must recognize which packet to pass through. (Dwight)

      1. 
         In my yesterday’s presentation, RA is also transmitted as unicast. It’s a good presentation. (Gabor)
