If you keep two or more links, keep them alive, and let them know their IP addresses each other, which can be coordinated by mobile hosts as the ends, links can cooperate to avoid broken links for a lot faster recovery than 0.05s.May work for detecting a dead access point in a wireless mesh,
That's not my point. My point is to avoid dead links. Base stations try sending packets to a MH and if it fails a few times, they forward the packet to other base stations which may have live links to the MH.
but it doesn't scale to WAN sized connections.
Regardless of whether links are wireless or wired, the coordination is necessary only within (small number of) links to which MH, the end, is attached, which means the coordination is a local coordination if coordinated by the end. There is no WAN involved for the coordination.
Consider the case where one endpoint is in Austria, the other is in
Boston,
and the node handling the mobility is in Japan. Now a router fails in Seattle. How long will it take for the endpoints to notice?
Huh?
(Alternatively, explain how you locate a suitable home base node
No home agent is involved for the recovery. Masataka Ohta
