Hi Alper,
Thanks for the explanation. Just another query.

I understand this protocol. I guess i am a little confused because i am trying to relate this to the RAN. I understand that there is one-one correspondance with access point ( bridge) and access router. I can see how this setup can work in a wireless LAN network but coming back to the RAN, the access point bridge equivalent would probably be RNC or some central controller servicing multiple access routers so the one to one relationship between access router, access point(bridge) is not valid anymore. In this case if several client access routers are registered with the same access point server the triggers will be notified to all the client access routers. Wouldn't this lead to confusion? How would the protocol address this issue. For eg, the server receives a link-up trigger for a access device but this information would be sent to multiple access router cleints, so which access router actually should consume the trigger?
Thanks,
Mohammed
