Hi Alper,
Just got on to the mailing list. There is interesting discussion on the Link-layer triggers draft. I had a few comments.
1. I am a little confused on location of the server. I dont understand where exactly this would reside in the infrastructure. For eg, in the RANwould this be on the RNC( radio network controller) but are we interested in all trigger notifications?. For eg, the mobile could change its association with a different Base station and have maintain same IP link. From an IP mobility perspective i would only be interested in triggers when the mobile is changing its IP attachment point.
2. On page 9 you have a section that says the following
"When a host receives a Link Up trigger, L2 address specified in the Event Data field indicates the link-layer address of the newly associated access point. Similarly, when an access router receives a Link Up trigger, L2 this address indicates the link-layer address of the newly associated access device."
How does the server distinguish an access router client from a host client and send different information in the trigger data?.
3. Can the host be registered to more than one server and receive more than one trigger notification at any time?. I believe it needs to maintain a unique registration at all times and send a deregistration to the old server everytime you move either as soon as you receive link-down on the old link or via new the new link.
I have some more concerns/questions will share them after you reply.
Thanks,
Mohammed
